The number of valence electrons is the same.

When moving down a group, the number of valence electrons do not change. This similarity yields the elements in the same groups to have same chemical properties. For example, elements in group 17 obtain one electron to stabilize as -1 ion.

In a group, all the elements have a same number of valence electrons. So their chemical properties are equal. But the physical properties vary.

Valence electrons are the electrons in outermost shell.The valence electrons remain same in a group. For example-Group-1 elements have 1 valence electron.
