What is wrong with or ambiguous about the phrase "four molecules of nacl"?

the NaCl is not considered a molecula

Explanation:

Sodium atoms, (Na +) and chlorine atoms, (Cl-) form a three-dimensional network. The cations and the anions are joined together by electrostatic attraction which we call ionic bonding

Molecules are atoms bound with chemical bond.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
