Answer 1

Answer:

Think about what you call your friends. Some of your friends might have full names (long names) and a nickname (short name). These are the words we use to tell others who or what we are referring to. Their full name is like the substances name and their nickname is like the substances formulae. Without these names your friends would have no idea which of them you are referring to. Chemical substances have names, just like people have names. This helps scientists to communicate efficiently.

It is easy to describe elements and mixtures. We simply use the names that we find on the periodic table for elements and we use words to describe mixtures. But how are compounds named? In the example of iron sulfide that was used earlier, the compound name is a combination of the names of the elements but slightly changed.

The following are some guidelines for naming compound,

The compound name will always include the names of the elements that are part of it.

A compound of iron (Fe) and sulfur (S) is ironsulfide (FeS)

A compound of potassium (K) and bromine (Br) is potassiumbromide (KBr)

A compound of sodium (Na) and chlorine (Cl) is sodiumchloride (NaCl)
