The chemical formula of simple compound represents the composition of a molecule of the compound in terms of the symbol of these elements present in it. In other words, the formula of simple compound tells us the kind of atoms as well as the number of atoms of various elements present in one molecule of the compounds.
In the formula of compounds, the elements are represented by their symbols and the number of atoms of each element are indicated by writing the digits 2, 3, 4 etc. as subscripts on the right hand side bottom of the symbol. But 1 atoms of any element is not represented specifically by writing as subscript. The symbol of element alone is enough to convey that.
lonic compounds -
Ionic compounds are formed by the combination between metals and non metals. While writing formula of ionic compounds, the metal element is written on the left hand side and the non-metal element is written on the right hand side. In naming the ionic compound, the metal element is nam as such but the name of non-metal element is changed to have the ending
Q 'ide' (like oxide, chloride, sulphide etc in
A compound that is made up two elements is called a binary compound. All ionic compounds are binary compounds since they are made up of a metal and a non-metal.
