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 »

The element manganese has seven valence electrons. The electronic configuration of manganese is [Ar] 3d5 4s2. The atomic number of manganese is 25 and it has 25 electrons out of which seven electrons are in the last shel... More »

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 »

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 »
