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 »

Atoms of elements in group 16 or group 6A of the periodic table of elements have six valence electrons. Group 16 and group 6A refer to the same elements, known as chalcogens, which are oxygen, sulfur, selenium, tellurium... More »

Selenium contains four unpaired electrons in its outermost orbital. These electrons can form bonds with other elements and are called valence electrons. On the periodic table, selenium is element number 34; it is located... 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 »

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 »

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 »

Phosphorous has five electrons in its valence shell. Two are in the 3s orbital. The remaining three are distributed evenly among the three orthogonal 3p orbitals. More »
