The ground state electron configuration of Ga is _____.-[Ar] 4s² ... Rb, K, Na, Li (TIP: Atomic radii increase going down a group, because successively larger valence-shell orbitals are occupied by electrons. The discovery of this simple formula based on the well-established laws of electromagnetism was the first fundamental equation for understanding the energies of many-electron atoms, while various theories based on qualitative symmetry properties lead to complications. … paramagnetic with five unpaired electrons. Still magnesium In chemistry, excited state means that an electron from an orbital absorbs incoming radiation or a photon that corresponds to its energy level and hence is … 1 Answer. This configuration contains 8 electrons, which in the ground state would be oxygen. c) 5s! To write the electron configuration, you start with the normal electron configuration of the element and add or subtract the number of electrons that the charge indicates. Write the condensed ground state electron configuration for each a Br Ar 4s2 from CHEMISTRY 115 at University of Wisconsin, Eau Claire transition metal The valence shell of the element X contains 2 electrons in a 5s subshell.
