Which one is a compound?
A
Ni
B
F
C
Re
D
NaCl
Explanation: 

Detailed explanation-1: -Sodium chloride, commonly known as salt (although sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. With molar masses of 22.99 and 35.45 g/mol respectively, 100 g of NaCl contains 39.34 g Na and 60.66 g Cl.

Detailed explanation-2: -Something like table salt (NaCl) is a compound because it is made from more than one kind of element (sodium and chlorine), but it is not a molecule because the bond that holds NaCl together is an ionic bond. If you like, you can say that sodium chloride is an ionic compound.

Detailed explanation-3: -Sodium chloride or table salt is a mineral substance belonging to the larger class of compounds called ionic salts.

Detailed explanation-4: -Sodium chloride is a simple compound with only two elements: sodium (Na) and chloride, which is the negatively charged ionic form of chlorine (Cl). This is why its chemical formula is NaCl.

Detailed explanation-5: -A compound is formed when atoms of two different elements combine; therefore, it is a type of molecule. Sodium chloride (NaCl) is formed when an electron is transferred from an atom of sodium to an atom of chlorine to form an ionic bond between them. Therefore, the species contains a chemical bond and is a molecule.
