Question

1. type the correct answers in the blanks. refer to the periodic table. how many electrons does nitrogen have? __ what period is nitrogen in? how many energy levels does nitrogen have? __ 9) choose all that apply. refer to the periodic table. what two sublevels does nitrogen have? (refer to figs. 5.4 and 5.5.) s f p d

Explanation:

Step1: Find nitrogen's atomic number

Nitrogen (N) has an atomic number of 7, so it has 7 electrons.

Step2: Locate nitrogen on periodic table

Nitrogen is in the 2nd row (period) of the periodic table.

Step3: Determine nitrogen's energy levels

The period number equals the highest occupied energy level, so nitrogen has 2 energy levels.

Step4: Identify nitrogen's sublevels

Nitrogen's electron configuration is $1s^22s^22p^3$, so it uses s and p sublevels.

Answer:

8)

• How many electrons does nitrogen have? 7
• What period is nitrogen in? 2
• How many energy levels does nitrogen have? 2

9)

• $\square$ s
• $\square$ p
• $\square$ f
• $\square$ d
