Question

(3 points) the third energy level can hold up to the first energy level can hold up to the second energy level can hold up to 8 electrons 18 electrons 39 electrons 20 electrons 2 electrons

Explanation:

Step1: Recall electron energy level rules

The formula for the maximum number of electrons in an energy level \( n \) is \( 2n^2 \).

Step2: First energy level (\( n = 1 \))

For \( n = 1 \), \( 2(1)^2 = 2 \) electrons. So "The first energy level can hold up to" connects to "2 electrons".

Step3: Second energy level (\( n = 2 \))

For \( n = 2 \), \( 2(2)^2 = 8 \) electrons. So "The second energy level can hold up to" connects to "8 electrons".

Step4: Third energy level (\( n = 3 \))

For \( n = 3 \), \( 2(3)^2 = 18 \) electrons. So "The third energy level can hold up to" connects to "18 electrons".

Answer:

• The third energy level can hold up to: 18 electrons
• The first energy level can hold up to: 2 electrons
• The second energy level can hold up to: 8 electrons
