Explanation:

Step1: Recall periodic - table group property

Elements in the same group have the same number of valence electrons.

Step2: Determine sodium's valence electrons

Sodium (Na) has 1 valence electron. It is in Group 1 of the periodic table.

Step3: Find potassium's valence electrons

Since sodium and potassium are in the same group, potassium also has 1 valence electron.

Answer:

B. 1
