Question

Explain how the element sodium is monovalent. Write answers to the question and explain your answers.

Answer 1

the atomic numver of sodium is 11

its atomic cinfiguration is 2 8 1

there is one valence electron in its outer shell

so it can only donate 1 electron easilly to complete its octet and be stable.

so Sodium metal is monovalent

Answer 2

HERE IS YOUR ANSWER
as we know that the at no of Na(sodium) is 11
so, electronic configuration=2,8,1
since its balance shelly has 1 electron so it needs tk donate this electron to attain stability to its naresh noble gas Neon
so it is monovalent
