Answer:
Compound can be represented as a molecular formula,empirical formula, structural formula,ball and stick model, space filling model.
Explanation:
Compounds can be represented as a chemical formula and a molecular model.
A chemical formula shows the number of atoms present in a compound. Whereas, the molecular model shows the geometry of a compound.
The chemical formula can be further divided into 3 types:
1)molecular formula: indicates the actual number of atoms in a compound.
2)empirical formula: indicates the relative number of atoms present in a compound.
3)structural formula: is illustrated in the forms of lines which actually shows the bond(such as covalent bond) and also shows how atoms are connected to each other in a molecule.
Molecular model is preferably a better way to represent a molecule. It is categorised into the following:
1)a ball and stick model: its a three dimensional representation of a compound. The atom(s) in a compound is represented by ball while, their chemical bonds are shown by sticks.
2)A space filling model: its a three dimensional structure,it represents the size and shape of the whole molecule,showing relatively how much space each atom in a molecule occupies.
