To find the number of outer electrons in an element, or valence electrons, look on the Periodic Table of Elements. Look at the last number of the electron configuration. An element that has an electron configuration of 2-7 has 7 valence electrons.

the no. of electron shells in an atom varies for every element in the periodic table, depending on its no. of electrons in the atom. the no. of shells of an atom of an element ca be derived through the period of the periodic table. elements in the 1st period has only 1 shell and so forth.
