No, they are not the same thing. Elemental sodium (Na) is a soft silvery metal that violently burns up when water touches it. Sodium Chloride (NaCl) is the scientific name for table salt - the same stuff you put on food.
NaCl
The formula unit of sodium chloride (NaCl) contain 60,33 % chlorine.
20 moles of elemental sodium and 10 moles of elemental chlorine, which contains two atoms per molecule.
I'm not sure I understand the question, but if you're asking what you get when you react elemental sodium (a reactive, caustic metal) and elemental chlorine (a reactive, poisonous, greenish-yellow halogen gas), the answer is sodium chloride, ordinary table salt.
elemental sodium metal reacts violently with chlorine gas to produce NaCl.
The compound sodium chloride (NaCl) is also known as table salt, and it is eaten by everybody. The elements sodium and chlorine are not eaten in their elemental form, however, and would be extremely toxic if you tried to eat them.
The elemental sodium (Na) does not react, the sodium cation ( Na+ ) combines with chloride anion ( Cl- ) when water is evaporated to form table salt (NaCl), but this is NOT considered to be a chemical reaction, it is a pure physical change in the state of matter (solution -> solid + water).
A compound, by definition is made up of more than one element. Sodium chloride (NaCl) is vastly different from both elemental sodium (which is a metal which dissolves when exposed to water) and chlorine (which is a gas that can kill you if you inhale enough of it). When you react both Sodium and Chlorine however.
Single-replacement
Sodium chloride has two atoms in the formula unit (NaCl): sodium and chlorine.
Sodium chloride is a compound.
Sodium chloride is not a cause of cancer.
