berillium has 4 electrons , 2 in its first shell and 2 in its second shell(which is the outermost ) so it should either lose 2 electrons to become \[Be ^{2+}\] or it should gain 6 electrons to complete its second shell. its more practical and easier to lose 2 electrons berillium loses 2 electrons to have a configuration as that of the noble gas helium(2)
