Current Question (ID: 7554)

Question:

$\text{The rule used to determine the maximum number of electrons in a subshell of an atom is:}$

Options:

1. $4l+2$
2. $2l+1$
3. $4l-2$
4. $2n^2$

Solution:

$\text{Hint: In an one orbital, maximum two electrons can fill.}$\n\n$\text{The maximum number of electrons that can be filled in a given subshell is given by 4l+2.}$\n\n$\text{For eg: in a d subshell, max 10 electrons can be filled. This can be explained by the following way as follows:}$\n\n$\text{For d subshell, l=2}$\n\n$4 \times 2 + 2 = 10 \text{ electrons}$
