Answer

Explanation:

Step1: Recall periodic - table 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. Its electron - configuration is 1s²2s²2p⁶3s¹.

Step3: Find potassium's valence electrons

Since potassium (K) is in the same group as sodium, it also has 1 valence electron.
