Question

1. choose the best answer. which sublevels are found in the 4th energy level of an atom? s and p s, p, d, and f s, p, and d s only 10) type in the correct answers. what is the maximum number of electrons each level can hold? a. sublevel 1: __ b. sublevel 2: c. sublevel 3: d. sublevel 4: __

Explanation:

Step1: Solve question 9

The 4th energy level ($n=4$) can have sublevels corresponding to $l=0,1,2,3$, which are s, p, d, f respectively.

Step2: Solve question 10a

Use electron capacity formula $2n^2$, $n=1$:
$\text{Electrons} = 2(1)^2 = 2$

Step3: Solve question 10b

Use electron capacity formula $2n^2$, $n=2$:
$\text{Electrons} = 2(2)^2 = 8$

Step4: Solve question 10c

Use electron capacity formula $2n^2$, $n=3$:
$\text{Electrons} = 2(3)^2 = 18$

Step5: Solve question 10d

Use electron capacity formula $2n^2$, $n=4$:
$\text{Electrons} = 2(4)^2 = 32$

Answer:

1. s, p, d, and f

10.
a. 2
b. 8
c. 18
d. 32
