Question:

Use the periodic table to identify the element with the following electron configuration.

{eq}a. \ [Ne]3s^23p^5 \\ b. \ [Ar]4s^23d^{10}4p^1 \\ c. \ [Ar]4s^23d^6 \\ d. \ [Kr]5s^1 {/eq}

Electron Configuration:


The electron configuration of any element in the periodic table represents the number of electrons which are present in each of the orbitals of the atom. It also represents the order in which electrons get filled in the orbitals according to energy. The outermost orbitals of the element determine the group and period of the periodic table in which the elements are present.
