D

A= Metallic

B= Conducts electricity as a solid

C= Covalent

D=Does not conduct electricity

Explanation:

it's c. elements are placed in rows based on how may valencies electrons have.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
