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. Web25 nov. 2024 · When the hydrogen atom makes the transition from the n=2 to the n=1 energy level, it emits a photon. this photon can be absorbed by to a singly ionized helium atom (he+) in its second energy level (ninitial=2), causing it to move to a higher energy level. to what final energy level number nfinal can the photon promote the helium ion?
