Step-by-step explanation:

Element: an element is a pure substance which is composed of only one type of atoms and that cannot be split or broken down into any simpler pure substance.

Examples of elements include:

Aluminum - it is composed of only atoms of aluminium. Each atom has 13 protons

Mercury - it is composed of only atoms of mercury. Each atom has 80 protons

Carbon - it is composed of only atoms of carbon. Each atom has 6 protons

Compound: a compound is a pure substance that is composed of two or more types of atoms (elements) in a fixed and definite proportion and that cannot be split into component elements by simple physical methods but only by chemical methods. Examples of compound include:

Ferrous sulphate: It is composed of atoms of Iron, Sulfur and Oxygen

Sucrose: It is composed of atoms of Carbon, Hydrogen and Oxygen.
