Oxygen has six valence electrons and is assigned a valence number of 2. This means it needs two electrons to satisfy its bonding requirements. When these two electrons come from two hydrogen atoms, the three atoms togeth... 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 »

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 »

Nickel has eight electrons in the 3d orbital and two electrons in the 4s orbital, which means nickel has 10 total valence electrons. The reason it has 10 is because nickel is a transition metal, so the d and s electrons ... More »

Like all alkaline earth metals, magnesium has two valence electrons, meaning there are two electrons in its outer shell. The valence electrons are the ones that an atom shares, gains or loses when interacting with additi... More »

Iron, or Fe, has 26 electrons, with two electrons in the outer valence shell. Iron is a transition metal and is both lustrous and easy to work with. Iron is also prone to rust, especially in damp environments. 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 »
