Webionized lithium Li2+. Solution 9.3 (a) Singly ionized helium is like hydrogen, except that there are two positive charges (Z = 2) in the nucleus. The square of the product of the positive and negative charges appears in the energy term for the energy levels. We can use the results for hydrogen, if we replace e2 by Ze2: E n =− Z2(13.6eV) n2 =− WebBy contrast, a completely ionized helium atom contributes a mass of 4 with a helium nucleus ( alpha particle) plus two electrons of negligible mass; hence, its average molecular weight is 4/3. As another example, a totally ionized nickel atom contributes a nucleus of mass 58.7 plus 28 electrons; its molecular weight is then 58.7/29 = 2.02.
