The electron configuration ending in np² indicates that there are two electrons in the p subshell of the outermost energy level. This typically corresponds to elements in group 14 of the Periodic Table, such as silicon (Si) and germanium (Ge). For example, the complete electron configuration for silicon is 1s² 2s² 2p⁶ 3s² 3p².
