Which type of substances have chemical bonds that are not directional and valence electrons that move freely between the atoms?
a) halogens
b) nonmetals
c) metals
d) salts

c) metals

Explanation:

In metallic bonding there are delocalized electrons that are shared by a number of metal cations. The electrons are free to move and are not confined to a single metal cation. These free flowing electrons give metals its specific properties such as ductility, malleability, electrical conductivity and more.

am i too late?

explanation:

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).
