The group number describes the type of element. it determines the number of valence electrons. It also describes its chemical properties.

Group number describes the number of valence electrons. It helps in estimating chemical properties of that element.For example-group-1 elements have 1 valence electronThe group number of an element is equal to the number of valence electrons. The number of valence electrons is responsible for the chemical properties. So the chemical properties of the element can be determined by the group number.
The group that fixes rates and regulates the railroads is called the ICC.
