Question

How many chlorine (Cl) atoms would be in 4 molecules of salt (4 NaCl)?
Question 6 options:

A. 1


B. 2


C. 3


D. 4

Answer 1

A molecule of sodium chloride, NaCl, consists of one atom each of sodium and chlorine. Hence, each molecule of NaCl has 2 atoms total. Pretty sure you can do the rest from there, but if you can't, the answer is 8.

I think I did that right... if I didn't... I'm sorry.

Answer 2

Answer: 4 molecules of NaCl contains 4 chlorine atoms.

Explanation:

Sodium chloride (NaCl) also known as salt is formed by transfer of 1 electron from $Na_{+}$ to $Cl^{-}$. The chlorine ion readily accepts one electron from sodium ion in order to complete its octet. Each sodium chloride (NaCl) molecule contains one sodium atom and one chlorine atom.

Thus, it can be concluded that 4 molecules of NaCl contains 4 sodium atoms and 4 chlorine atoms.
