1.	Difference between group 2A and 2B elements in modern periodic table ?
Answer» ong>Explanation: The alkaline EARTH METALS have TWO valence ELECTRONS in their highest-energy orbitals (ns2). They are smaller than the alkali metals of the same period, and therefore have higher IONIZATION energies. In most cases, the alkaline earth metals are ionized to form a 2+ charge. please mark my answer as brainliest
