Sodium has one valence electron, which makes it very reactive with halogens and other nonmetals. Sodium is an alkali metal that is never found in its pure form in nature. More »

The valence of sodium is one. Sodium has a valence of one because it only has one electron present on its outermost shell. The outermost shell of an atom is also known as its valence shell. 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 »

Alkali metals and halogens are likely to form ions because of a surplus or a lack of electrons in their valence (outermost) electron shells. In order for an alkali metal to become a stable ion, it must lose the single el... More »

Metals conduct electricity and heat better than nonmetals because their electrons can move more easily and thereby transfer energy. Also, metals have a more solid crystalline structure with less space between the electro... 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 »
