Question

What is the name of the compound with the formula NaF?

Answer 1

Hint: The given compound is the ionic compound where Na represents sodium ion and F represents the fluorine ion. One of them will be negative and the other will be positive which will then comprise the proper name of the compound.

Complete answer:
Let us see the basics before naming any chemical compound;
There are general rules to be followed while naming any compound, which are simple ionic compounds as;
The positive ion i.e. cation is named at first place and is the same as its chemical elemental name.
The negative ion i.e. anion is named at last place and is named by putting a suffix ‘-ide’ at the end of the name.
Thus, considering the given compound i.e. NaF;
The name can be stated as –
Na will be the positive ion and fluorine will be a negative ion i.e. the name will be stated as Sodium fluoride according to the above stated rules.

Note:
Do note that the rules of naming any compound is very specific and restricted as stated above. They cannot be changed at any condition, though has some exceptions on higher level classes of chemistry (not the point of discussion right now).
