Answer 2

Atoms are represented by symbols.

• Atoms are the smallest entities of an element.
• They are the building blocks of elements and symbols of the element basically reveal the type of atoms in it.
• Atoms combine together to give rise to molecules and subscripts are used against the symbol when more than one atom of a particular type is present.    
• For example, the symbol of hydrogen is H, for oxygen is O and the formula for water is H₂O, indicating that two atoms of hydrogen and one atom of oxygen is present.
