Question

please tell me answer​

Answer 1

Answer:

Answer is D)

Explanation:

Sodium (Na) electronic configuration is 2, 8, 1

Potassium (K) electronic configuration is 2, 8, 8, 1

So they have same valence electrons (=1).

Valence electrons is the number of electrons in the last shell of the atom.

Na and K both lose their valence electrons to form the cations (positive ions) Na+ and K+

They lose the valence electron to gain stability.

Answer 2

D) is your answer.
