Question

The chemical and physical properties of elements rely on the number of valence electrons. In periodic table, elements present in the same group have the same number of valence electrons. Therefore, elements present in the same group have similar chemical and physical properties​

Answer 1

The physical and chemical properties of elements depend on the number of valence electrons. Elements present in the same group have the same number of valence electrons. Therefore, elements present in the same group have similar physical and chemical properties.

Answer 2

Answer:

The chemical and physical properties of elements rely on the number of valence electrons. In periodic table, elements present in the same group have the same number of valence electrons. Therefore, elements present in the same group have similar chemical and physical properties
