Isoelectronicity

Isoelectronicity is an effect observed when two or more molecules have the same structure (positions and connectivities among atoms) and the same electron configurations, but differ by what specific elements are at certain locations in the structure. For example, CO, NO+, and N2 are isoelectronic, whilst CH3COCH3 and CH3N=NCH3 are not. In quantum mechanics, hydrogen-like atoms are ions with only one electron such as Li2+. These ions would be described as being isoelectronic with hydrogen.
