Which element is used to "paint" the skin to prevent infection from cuts and scratches

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).

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
