Question

The electron shell .............. is nearest to the nucleus

Answer 1

Electrons orbit the nucleus of an atom at different ranges, called shells. Eachshell has a different energy level, increasing the further it is from thenucleus. Each energy level is given a number called the principal quantum number, n. The closest shell has a value of n=1.

Answer 2

Answer:

The electron shell k is nearest to the nucleus

Explanation:

• The shell which is nearest to nucleus is K shell which is also known as 1 shell.
• First shell is known as K shell second shell is known as L shell and third shell is known as M shell and so on.
• Every shell consists of fixed number of electron
• The first shell can hold upto two(2) electrons,the second shell can hold  upto 8 electrons(2+6) and third shell can hold upto 18 electrons(2+6+10).
