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 »

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 »

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 »

A polar bond is a type of bond that is formed between two atoms that are sharing an electron, where one atom has a stronger attraction, or pull, on the electron than the other. A polar bond is a type of covalent bond, wh... More »

A nonpolar covalent bond is a type of bond between two identical nonmetallic atoms where the two electrons are shared equally by each atom. It is different from a polar covalent bond, in that involves the electrons being... 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 »

Atoms become chemically stable by losing, gaining or sharing electrons with other atoms to fill up their outermost electron shell. This allows them to obtain the electron configuration of the nearest noble gas. More »
