Basics of Chemistry Part-03 (Shell and Sub-shell Electronic configuration ) In the previous two parts of this series, we have learnt about details of first 20 elements, calculated their atomic weight and drawn their atomic structures. Not seen Part-1 and Part-2 yet?? Click here for Basics of Chemistry || Part-01 || Click here for Basics of Chemistry || Part-02 || In this part we will be discussing about shell(orbit) and sub-shell(orbital) electronic configuration of first 20 elements. We will learn how to write these electronic configurations and what information can be obtained from them. So, let us start... As we have seen in the atomic structure, the first shell (orbit) can accommodate maximum 2 electrons, we will first try to put 2 electrons in 1st orbit i.e., K-Shell (orbit). But, Hydrogen contains only 1 electron as a whole, so it contains only 1 electron in the 1st shell (Orbit). Then, the 2nd orbit i.e., L-Shell can accommodate maximum 8 electrons. So, we will ...
Classification of Elements Part-2 Very short questions and answers for S.E.E. students Questions and answers to practice for S.E.E. examination 1) Write the electronic configuration of potassium in terms of sub-shell. Answer: The electronic configuration of potassium in terms of sub-shell is K-1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹. 2) In what groups do magnesium and nitrogen belong in modern periodic table? Answer: In modern periodic table, magnesium belongs to group IIA (2) and nitrogen belongs to group VA (15). 3) What is common name given to the group I elements in the modern periodic table? Answer: The group I of modern periodic table is commonly named as 'alkali metals' as they contain elements which form alkali on reacting with water. 4) In which group of modern periodic table are alkaline earth metals and halogens kept? Answer: In modern periodic table, alkaline earth metals are kept in group 2 and halogens are kept in group 17. 5) In what groups, noble gases, most reactive non...

The Earth in the Universe The universe is a vast space and everything we see around us lies in this universe. The planets, sun, moon, stars, asteroid, black hole, comets, galaxies, etc. lies in this universe. This chapter is not that much vast to understand. Students must be curious about the topic for their understanding. Many of the students seems interested in this topic. I have made some videos on this topic. The link is given below.

Basics of Chemistry Part-04 (Valancy, charge & ions ) In the previous three parts of this series, we have learnt about details of first 20 elements, calculated their atomic weight, drawn their atomic structures and learnt about shell & sub-shell electronic configurations. Not seen Part-1, Part-2 & Part-3 yet?? Click here for Basics of Chemistry || Part-01 || Click here for Basics of Chemistry || Part-02 || Click here for Basics of Chemistry || Part-03 || In this part we will be discussing about valencies and radicals of the first 20 elements about which we have studied in previous parts. We will first learn to calculate valencies from shell and sub-shell electronic configurations and then we will be looking towards ions. So, let us start without any delay... After understanding shell electronic configuration, it is easy to predict valencies of the elements just by looking their last number. For example, the Electronic configuration (E.C.) of Lithium i...
