Which statement about Niels Bohr’s atomic model is true? Higher orbits have lower energies. Each orbit has a specific energy level. Electrons can exist in any energy level. Orbits close to the nucleus have no energy.

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).

a:

by the combination of an unlimited number of elements

it is a solid
