Question

How many electrons can the n=4 shell hold? a. 8b.16c.32d.64?

Answer 1

The maximum the fourth shell can have is 32.

Answer 2

Answer:

c.32

Explanation:

Hello,

In this case, it is possible to determine it by building the subshells organization for the first four shells as shown below:

$1s^2\\2s^2\ 2p^6\\3s^2\ 3p^6\ 3d^{10}\\4s^2\ 4p^6\ 4d^{10}\ 4f^{14}$

In such a way, counting the electrons at the n=4 shell, the result is 32 (2+6+10+14), so the answer is c.

Best regards.
