Answer:
The elements in the same group has similar number of valence electrons. They have identical number of electrons in their outermost shell. e.g. All the alkali metals in Group 1 have 1 valence electron, so they all tend to react the same way with other substances.
Explanation:
a group is a vertical column in the periodic table of the chemical elements. ... Each element within a group has similar physical or chemical properties because of its atom's outermost electron shell (most chemical properties are dominated by the orbital location of the outermost electron).
