A triply ionized beryllium ion, Be3+ (a beryllium atom with three electrons removed), behaves very much like a hydrogen atom except that the nuclear charge is four times as great.1)How does this compare to the ground-level energy of the hydrogen atom? 2)What is the ionization energy of Be3+?3)How does this compare to the ionization energy of the hydrogen atom?4)For a given value of n, how does the radius of an orbit in Be3+ compare to that for hydrogen?
