Consider the hydrogen atom,singly ionized helium atom,and the doubly ionized lithium atom.Arrange these atoms from highest energy ground state to lowest energy ground state. A)H,He⁺,Li⁺⁺ B)Li⁺⁺,He⁺,H C)H,Li⁺⁺,He⁺ D)Since each of these atoms has only one electron,they all have the same energy ground state.

Question

Quizplus · Accepted Answer

The energy of an electron in an atom is inversely proportional to the square of the atomic number. Therefore, the hydrogen atom has the highest energy ground state, followed by the singly ionized helium atom, and then the doubly ionized lithium atom.
