When comparing bromine to chlorine, bromine has A. Fewer protons in its nucleus.
B. A weaker effective nuclear charge
C. More valence electrons
D. More electron shielding

what are the two models

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).

they are all solids.
