Question

Please anyone explain me this

Answer 1

$\huge\bigstar\underline\mathfrak{Hello\:mate!}$

The pic you have provided tells us the atomic diagrams of first twenty elements. So, in these, the shells are being numbered as K,L,M, and so on. Also, the number of electrons present in the elements are represented as dots in the orbits. And the first shell K can have two electrons at the most. The second shell L can accommodate 8 electrons, etc.

To draw these on your own,

1. Draw a small circle enclosed within many orbits as shown in pic.
2. Make the electrons as dots in the orbits (depends upon its atomic number)
3. Find the number of neutrons by :- Mass number - Atomic number
4. Write the number of protons and neutrons in the Central circle.

Mark me as the brainliest if this helps...✌
