Expert Answer

Step 1

The valence electrons of an atom are present in the outer most shell. An atom loses or gains electrons to make a stable electronic configuration. The sodium, potassium, and magnesium are metals. Sodium (Na) and potassium (K) belong to group 1 and they contain one valence electrons. Magnesium belongs to group 2 and it contains two valence electrons. Na and ...
