Question

What is the maximum number of electrons in the n = 3 level?

Answer 1

Answer: 18

Explanation:

The maximum number of electrons in the n = 3 level can be found using the formula for the maximum number of electrons in an energy level, which is given by:

• 
  `2n^(2)`

Here, n = 3, so we can substitute this value into the formula and solve for the maximum number of electrons:

• 
  `2n^(2) = 2(3)^(2) = 2(9) = 18`

Therefore, the maximum number of electrons in the n = 3 level is 18.

Answer 2

The maximum number of electrons in the n = 3 level can be found using the formula:

• 
  `2n^2`

where:

• n is the principal quantum number.

Substituting n = 3, we get:

• 
  `2(3)^2`

Simplifying this expression, we get:

• 
  `2(9) = \fbox{18}`
