The properties of valence electrons are determined by the total number of electrons in an atom's outer shell. Atoms with similar numbers of valence electrons are classified into a specific group of elements, which may th... More »

A valence electron is a type of electron present in an atom that works to aid in the process of chemical bond formation with other atoms. These electrons are present in the outer shell of an atom. More »

Helium has two valence electrons. As an element, helium is very stable and contains a single s-orbital on its outer shell. 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 »

With an atomic number of 4, beryllium has four electrons: two electron shells surround the atom's nucleus and two electrons in each shell. Beryllium is a rigid metal with an atomic mass of 9.0122. It is lightweight but s... 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 »

Mercury has two valence electrons, both of which sit in the atom's 6s shell. A valence electron is an electron in the outermost shell of an atom. Valence electrons are capable of bonding with the valence electrons of oth... More »
