Hydrogen has one valence electron because it is an element found in group 1 of the periodic table. It is a simple task to find the number of valence electrons from the periodic table by looking at the group number found ... More »

Sulfur has six valence electrons, meaning that each atom of this element has six electrons in its outermost shell. The number of valence electrons that each element has can be predicted based on its location on the perio... More »

There are multiple elements that have six valence electrons, including oxygen and sulfur. These elements can be found in the sixteenth group in the vertical column of the periodic table, also known as the chalcogens. More »

To find the valence electrons in an atom, identify what group the element is in. An element in group 1A has 1 valence electron. For example, Li is in group 1A, so that means it has one valence electron. If the element is... More »

Francium has one valence electron as a member of the alkali metal group on the periodic table of elements. That valence electron is in the s-orbital of the seventh energy level. More »

The smallest atom in the periodic table in terms of mass is hydrogen, which has only one proton and one electron. Hydrogen has no neutrons. The element has an atomic number of 1 and atomic weight of 1.00794, making it th... More »
