Valence electrons are electrons located in the outermost shell, or energy level, of an atom. These electrons are responsible for the interaction between atoms and the formation of chemical bonds. Valence electrons are the least tightly held by the atom since they are the furthest from the nucleus. The number of valence electrons an element has determines its reactivity, electronegativity, and the number of bonds it can form.
- Valence electrons are the electrons in the outer energy level of an atom that can participate in interactions with other atoms.
- They are the electrons that participate in the formation of a chemical bond or a molecule.
- The total number of electrons present in the last shell orbit is known as the valence electron.
- Elements in the same group of the periodic table have the same valency, which is related to the number of electrons in the outer shell.
