WebAnswer (1 of 2): ‘Be’ belongs to second period and second group. Upward in a group, size is less (number of shells), and Z-eff(effective nuclear charge- attraction by nucleus) on outermost electron is more, leading to higher ionisation energy to create Be(+2) cation. As it does not easily loose a...
