SSC Chemistry 5th Week Assignment 2021 Answer

SSC Chemistry 2nd Week Assignment 2021

SSC candidates have their first assignment in the Chemistry subject in the 2nd Week. Chemistry is determined from the third chapter of the first assignment. The title of the third chapter is the structure of matter. How a substance is formed and the different states of matter are discussed in this chapter. Thus, from the 2nd-week chemistry assignment of SSC, we will learn about the composition of matter. In order to solve the SSC 2nd week chemistry assignment correctly, one has to acquire detailed knowledge about substances and the basics of matter. Otherwise, it is not possible to give the answer to SSC 2nd week chemistry assignment correctly. So before writing the solution or answer of the SSC 2nd week chemistry assignment one must acquire knowledge about the content of the assignment.

Answer: প্রতীকের পাশে উল্লেখিত ভরসংখ্যাবিশিষ্ট মৌলের নিউট্রন সংখ্যা, বাের মডেল

Chemistry has been asked to prepare a report on electron configuration as the work of the 2nd Week assignment. Some symbols and their mass numbers are mentioned as signals to create the report. These must be used to create the report. A report must be prepared on the number of neutrons in the element with the mass number mentioned next to the symbol, the atomic structure according to the model, the electron configuration at the energy level, and the electron configuration at the substratum. The numbers mentioned in the chemistry assignment are given with the help of the figure below.

Here the structure of the atom according to the Bohr model should be mentioned along with the diagram and also the electron configuration of energy level and sub-energy level should be discussed. So those examinees who are worried about SSC 2nd Week chemistry assignment should follow our instructions. We will provide guidance on the solution of the 2nd Week assignment of chemistry or writing the answer sheet. Also for the convenience of students, we will upload the solution or answer of SSC 2nd Week chemistry assignment in PDF format. If anyone wants to download the solution or answer of 2nd Week chemistry assignment then visit our website.

Students need to follow a number of guidelines for writing the solution or answer of the 2nd Week chemistry assignment. Creating a solution or answer to the assignment by following the instructions below will definitely yield excellent results. As a result, it will be helpful to make the results of SSC 2021 better. Now I will give the instructions so that the students can create chemistry assignments in a good way by following them. The answer must be the number of neutrons of 4 elements. Also the structure of the atom according to the model of 4 elements has to be described with diagrams. Electron arrangement should be shown in the energy level of 4 elements. It is also necessary to show the electron configuration of the sub-layer of 4 elements. If you follow the above guidelines and create a solution or answer sheet for the chemistry assignment, you will definitely get very good results.

We can learn a lot from the chemistry assignment of SSC 2nd Week. For example, we can calculate the number of electrons, protons and neutrons in an atom. Rutherford and Bohr will also be able to describe the atomic model of atomic structure. I can arrange the electrons of the atom in different orbits of the atom and in different layers of the orbit.

SSC Chemistry 3rd Week Assignment 2021

Chapter Four has been selected as the SSC 3rd Week chemistry assignment. That is, all the questions of the 3rd Week chemistry assignment will be asked from the fourth chapter. And if you understand the fourth chapter well, it will be easier to give the solution or answer of the 3rd Week chemistry assignment. So before making a solution or answer of the SSC 3rd Week chemistry assignment one must acquire sufficient knowledge about the fourth chapter stage table. Because if you don’t have any knowledge about the periodic table, you can’t answer any questions about the periodic tables. So if you want to give a solution or answer to SSC 3rd Week chemistry assignment, you must follow the chapter.

Answer: Li, Be, Na, Mg মৌল চারটির ইলেকট্রন বিন্যাসের আলােকে পর্যায় সারণিতে অবস্থান

A report will have to be prepared as the work of the 3rd Week chemistry assignment. Students of SSC 2021 are asked to prepare a report from the periodic table to provide solutions or answers to the 3rd Week chemistry assignment. The task of the assignment is to make a report on the position in the periodic table in the light of the electron configuration of the element, the relative ionization energy and the properties of the group or class corresponding to the element. Here is a list of the four elements that make up the report. Assignment work should be completed based on this list. That is, the report has to be prepared and submitted.

What can we learn from SSC 3rd Week chemistry assignment?

There is a lot to learn about periodic tables and different elements from the SSC 3rd Week chemistry assignment. For example, it will be able to determine the relationship of the major groups in a periodic table with the electron configuration at the external energy level of the element. Students will be able to identify the stage of an element if they can complete the 3rd Week chemistry assignment properly. Also, by knowing the position of an element in the periodic table, one can get an idea about its physical and chemical properties. So you can tell the reason for the special naming of the elements. Also be able to show interest in estimating the religion of the elements by following the periodic table.

How to prepare solution or answer sheet of SSC 3rd Week chemistry assignment? In order to solve the 3rd Week SSC 2021 Chemistry Assignment or to prepare the answer sheet, the answer sheet must present some significant issues. The issues are- to determine the stages of 4 elements including electron configuration. It is not possible to get the full number if the stages are not determined correctly. Also 4 elements including electron configuration have to be determined correctly. The ionization energy of different elements of class and stage has to be compared properly. Features must also be specified with the special names of the two groups or classes. The above issues must be mentioned in the answer sheet. Besides, it is not possible to get very good marks through assignments. So if you want to get the best results they must follow our instructions.

নমুনা সমাধান

(ক) মৌলগুলাের ইলেকট্রন বিন্যাস লক্ষ্য করলে দেখা যাবে যে, লিথিয়াম (Li) এর ক্ষেত্রে সর্বশেষ ইলেকট্রন দ্বিতীয় শক্তি স্তরে প্রবেশ করেছে। তাই আমরা বলতে পারি, Li(3) এর পর্যায় হচ্ছে 2।

অনুরূপভাবে, FT বেরিলিয়াম (Be) এর ক্ষেত্রে সর্বশেষ ইলেকট্রন দ্বিতীয় শক্তি স্তরে প্রবেশ করেছে। তাই আমরা বলতে পারি, Mg(12) এরপর যায় হচ্ছে 3।

(খ) গ্রুপ বা শ্রেণি নির্ণয় :

প্রশ্নে উল্লেখিত মৌলগুলাের ইলেকট্রন বিন্যাস :

মৌলগুলাের ইলেকট্রন বিন্যাস লক্ষ্য করলে দেখা যাবে যে, লিথিয়াম (Li) এর ক্ষেত্রে সর্ববহিঃস্থ শক্তিস্তরে একটিমাত্র ইলেকট্রন রয়েছে। তাই আমরা বলতে পারি,Li(3) এর গ্রুপ হচ্ছে 1।

অনুরূপভাবে, বেরিলিয়াম (Be) এর ক্ষেত্রে সর্ববহিঃস্থ শক্তিস্তরে দুইটি ইলেকট্রন রয়েছে।

তাই আমরা বলতে পারি, Be(4) এর গ্রুপ হচ্ছে 2। সােডিয়াম (Na) এর ক্ষেত্রে সর্ববহিঃস্থ শক্তিস্তরে একটিমাত্র ইলেকট্রন রয়েছে। তাই আমরা বলতে পারি, Na(11) এর গ্রুপ হচ্ছে 1। ম্যাগনেসিয়াম (Mg) এর ক্ষেত্রে সর্ববহিঃস্থ শক্তিস্তরে দুইটি ইলেকট্রন রয়েছে। তাই আমরা বলতে পারি, Mg(12) এর গ্রুপ হচ্ছে 2।

(গ) তুলনামূলক আয়নীকরণ শক্তি :

আমরা জানি, একই পর্যায়ে যত বাম দিক থেকে ডান দিকে যাওয়া যায়, অর্থাৎ পারমাণবিক সংখ্যা যত বাড়তে থাকে পরমাণুর আকার ততােই হ্রাস পেতে থাকে। আর পারমাণবিক আকার হ্রাস পেলে পরমাণুর আয়নীকরণ শক্তি বাড়ে। কারণ, এতে একটি করে ইলেকট্রন যুক্ত হয় এবং নিউক্লিয়াসের সাথে আকর্ষণ বেড়ে যায়।

আবার, একই গ্রুপে উপর থেকে নিচে আসলে একটি করে নতুন শক্তিস্তর যুক্ত হয়। এর ফলে পারমাণবিক ব্যাসার্ধ বেড়ে যায়। ফলে আয়নিকরণ শক্তি কমে যায়। অর্থাৎ এখানে বেরিলিয়ামের (Be) আয়নীকরণ শক্তির মান সবচেয়ে বেশি।

আয়নিকরণ শক্তির ক্রম হবে নিম্নরূপ : 𝐵𝑒>𝐿𝑖>𝑀𝑔>𝑁𝑎 ।

(ঘ) মৌল সংশ্লিষ্ট গ্রুপ বা শ্রেণির বৈশিষ্ট্য :

প্রশ্নে উল্লেখিত মৌলগুলাের ইলেকট্রন বিন্যাস লক্ষ্য করলে আমরা দেখতে পাই যে, Li(3) এর গ্রুপ হচ্ছে 1। Be(4) এর গ্রুপ হচ্ছে 2। Na(11) এর গ্রুপ হচ্ছে 1। Mg(12) এর গ্রুপ হচ্ছে 2।

অর্থাৎ লিথিয়াম (Li) এবং সােডিয়াম (Na) একই গ্রুপে অবস্থিত এবং তাদের গ্রুপ হচ্ছে 1। আবার বেরিলিয়াম (Be) এবং ম্যাগনেসিয়াম (Mg) একই গ্রুপে অবস্থিত এবং তাদের গ্রুপ হচ্ছে 2.

গ্রুপ -1 (ক্ষার ধাতু)

পর্যায় সারণির ১নং গ্রুপে ৭টি মৌল আছে। এদের মধ্যে হাইড্রোজেন ছাড়া বাকি ৬ টি মৌলকে (লিথিয়াম, সােডিয়াম, পটাশিয়াম, রুবিডিয়াম, সিজিয়াম এবং ফ্রানসিয়াম ) ফ্রানসিয়াম) ক্ষারধাতু বলে।

এই ছয়টি মৌলের প্রত্যেকটি পানিতে দ্রবীভূত হয়ে এই ছয়টি মৌলের প্রত্যেকটি পানিতে দ্রবীভূত হয়ে হাইড্রোজেন গ্যাস এবং ক্ষার তৈরি করে বলে এদেরকে ক্ষারধাতু (Alkali Metals) বলা হয়।

এ ধাতু গুলাে খুবই সক্রিয়। এরা আয়নিক বন্ধন গঠন করে। এরা নরম ও চকচকে হয়।

গ্রুপ- 2 (মৃৎক্ষার ধাতু)

পর্যায় সারণির ২নং গ্রুপে বেরিলিয়াম, ম্যাগনেসিয়াম, ক্যালসিয়াম, স্ট্রনসিয়াম, বেরিয়াম এবং রেডিয়াম এই ৫ টি মৌল আছে। এই মৌলগুলােকে মৃৎক্ষার ধাতু বলে।

এই ধাতুগুলােকে মাটিতে বিভিন্ন যৌগ হিসেবে পাওয়া যায়।

আবার, এরা ক্ষার তৈরি করে। এজন্য সামগ্রিকভাবে এদের মৃৎক্ষার ধাতু (Alkaline Earth Metals)।

এদের হাইড্রোক্সাইড গুলাে এসিডের সাথে বিক্রিয়া করে লবণ ও পানি উৎপন্ন করে। এরা আয়নিক বন্ধন গঠন করে।
