Write an electron configuration for an excited state of sodium in which one of the 2p electrons jumps up to the 3p orbital.

the atomic mass is the bottom number on the element.

-steel jelly

c. 75.7

i think that is the right

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).
