The quantum mechanical model of the atom a) is concerned with the probability of finding an electron in a certain position b) has many analogies in the visible world c) defines the exact path of an electron around the nucleus d) was proposed by neils bohr.

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).
