Valence electrons are the electrons in the outermost shell of an atom. These electrons are important in bonding and magnetism. For example, carbon has 4 valence electrons. It can make 4 covalent bonds to fulfill the octet rule. Also, if an atom has unpaired electrons, it is called paramagnetic and if an external magnetic field is applied, it will be attracted. If all of the electrons are paired, it is diamagnetic and will be repelled by an external magnetic field.

What is the number of valance electrons in atoms from alkali metals?
they have one valence electron. this is why they are so highly reactive and cannot be found pure in nature.

Hydrogen has only one electron. Just the one. And it is a valence electron.
How many valence electrons does Na have?
One. Sodium is found in Group 1, which is characterized by having one valence electron, so by extension, potassium, rubidium, cesium, and francium also have one valence electron.
What is the valence electron configuration for the magnesium atom?
