Question

**Calculate maximum number of electrons in 4th energy level.

Answer 1

Answer:

According to Neils Bohr, the maximum number of electrons that can be occupied in a energy level can be given by the equation: 2n²

Here, n refers to the energy level and the whole answer obtained is the maximum number of electrons present in that shell.

According to the question,

We are required to find the number of electrons in 4th shell

Hence n = 4. Substituting in the formula we get,

=> 2n² = 2 ( 4 )² = 2 * 16 = 32 electrons

Hence 32 electrons is the maximum number of electrons that can be occupied by the 4th energy level of an atom.

Answer 2

2n^2 where n is the energy level. As it the 4th energy level:
2(4)^2=2(16)=32
