Detailed explanation-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.
Detailed explanation-2: -Reason: Elements in a group have the same number of electrons in the outermost shell hence they have similar chemical properties.
Detailed explanation-3: -Elements within the same group have the same number of electrons in their valence (outermost) shells, and they have similar electron configurations. They exhibit similar chemical properties.
Detailed explanation-4: -Elements in the same column of the Periodic Table have similar chemical properties.
Detailed explanation-5: -One such grouping includes lithium (Li), sodium (Na), and potassium (K): These elements all are shiny, conduct heat and electricity well, and have similar chemical properties.
