Answer» ong>Answer: Valence ELECTRONS, VALENCY, atomic size, ionization ENERGY, metallic character, electron-positivity, electron-negativity and reactivity are the characteristics of groups. The atomic radius of the element (i.e. atomic size) LYING in a group increases as we go up from TOP to bottom in a group.
