Question

How is it possible that when you combine Na (sodium) an explosive metal, and Cl (chlorine) a poisonous gas it creates NaCl (salt) that we put on our food?

Answer 1

They share an outer electron.

Step-by-step explanation:

For complementary reasons, sodium and chlorine are both highly reactive. Sodium has a single electron in its outermost, third shell, and chlorine has one electron less than eight in its outermost, fourth shell. They form a strongly bound molecule by sharing that outer electron.
