    The electron configuration for zinc is [AR] 4S2 3D10. Zinc has atomic number 30 and is the first element in group 12 of the periodic table. The last option is the correct one. Electron configuration has to do with the distribution of electrons in an atom or molecule in atomic or molecular orbitals. Electronic configuration of an element is very important because it is the key to the properties of that element.
