Question

alkali and alkaline earth metals easily from cations

Answer 1

because they lose valence electron easily.The alkali metal have 1 valence electron and the alkaline earth metal have 2 valence electrons in its valance shell (outermost shell). They need 8 valence Electrons to become stable and it is easier to lose 1 or 2 Valence Electrons instead of gaining 6 or 7 electrons. and when an atom loses electron It's become more positive that means cation...
