Why do elements of the same group have similar chemical properties?

Answer and explanation

Correct answer: They have the same number of valence electrons

Elements in the same group have the same number of valence electrons in their outermost shell. Since valence electrons mainly determine bonding and chemical reactions, these elements show similar chemical properties. The same number of electron shells indicates the same period, not the same group. Exam tip: remember that groups relate to valence electrons, while periods relate to electron shells.
