Explanation:

A chemical symbol designates an element that belongs to the periodic table.

A chemical formula combines two or more symbols and it represents a chemical compound. We notice that the chemical symbols are followed often by a subscript that represents the mole proportions of the next element.

A chemical symbol is used to show an element that is not combined with any other elements. I'll list some examples.

H = hydrogen

He = helium

Li = lithium

N = nitrogen

Na = sodium

Notice that symbols can have 1 or 2 letters. The first letter is capitalized, the second must be written with a lowercase letter.

A chemical formula gives the type and number of elements that are found in a chemical compound. Here are some examples.

CO = carbon monoxide (carbon with oxygen)

H2O = water (hydrogen with oxygen)

NaCl = sodium chloride/salt (sodium with chlorine)

C6H12O6 = glucose (carbon, hydrogen and oxygen)
