How To Find The Valence Number 2. find the electron configuration for the element you are examining. once you know an element's electron configuration, finding its number of valence electrons is quite simple (except, of course, for the transition metals.) if you're given the configuration from the get go, you can skip to the next step. Valence electrons are those electrons that reside in the outermost shell surrounding an atomic nucleus. valence electrons are of crucial importance because they lend deep insight into an element’s chemical properties: whether it is electronegative or electropositive in nature, or they indicate the bond order of a chemical compound – the number of bonds that can be formed between two atoms.

How To Identify The Valence Electron An explanation and practice for finding the number of valence electrons for elements on the periodic table. this is a key first step for drawing lewis dot s. Valence electrons are the electrons that reside in the outermost energy level of an atom and are, therefore, the most accessible for the formation of chemical bonds. the number of valence electrons in one atom of each element is easily determined based on its position in the periodic table . for the main group elements (groups designated with a.

For neutral atoms, the number of valence electrons is equal to the atom’s main group number. the main group number for an element can be found from its column on the periodic table. for example, carbon is in group 4 and has 4 valence electrons. oxygen is in group 6 and has 6 valence electrons. As a gas or vapor, the halogens all had a pungent odor. after the development of quantum mechanics, it was shown that the halogens all had seven valence electrons, supporting their original placement into the same group on mendeleev's periodic table. figure 11.1.1 11.1. 1: periodic table by dmitri mendeleev, 1871.
