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?

1. choose all that apply. refer to the periodic table.

what two sublevels does nitrogen have? (refer to figs. 5.4 and 5.5.)
d
f
p
s

Explanation:

Step1: Determine the number of electrons

The atomic number of nitrogen is 7. For a neutral atom, the number of electrons equals the atomic number. So, nitrogen has 7 electrons.

Step2: Find the period

In the periodic table, nitrogen is in period 2.

Step3: Calculate the number of energy levels

The period number indicates the number of energy levels. Since nitrogen is in period 2, it has 2 energy levels.

Step4: Identify the sublevels

The electron configuration of nitrogen is \(1s^{2}2s^{2}2p^{3}\). So, the sublevels are \(s\) and \(p\).

Answer:

7
2
