How do you find the number of protons for any atom

Protons are subatomic particles that are found in the nucleus of an atom. One way to find the number of protons an atom has is by looking at that specific element on the periodic table.

Usually, the atomic number (number of protons) will be under the name of the element or the element symbol depending on which periodic table you have.

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).
