Question

how many electrons in a given atom can have the following quantum number n= 3

​

Answer 1

Explanation:

Explanation: No two electrons in an atom can have the same set of quantum numbers. The first quantum number is the principle quantum number , which is n=3 . This means the electron is in the third energy level (shell).

Answer 2

Answer:

28

Explanation:

As the formula for electrons in n shell is 2n²

so 1 shell - 2n² - 2(1)² -2

2 shell - 2n²- 2(2)²- 8

3 shell - 2n²- 2(3)²- 18

total 28
