Valence Electrons
Valence electrons are the outermost electrons in an atom and play a key role in chemical reactions and bonding. They determine how an atom interacts with others. For example, in the electron configuration, which describes how electrons are arranged, valence electrons are found in the highest energy level. Atoms with full outer shells are generally stable and less reactive, while those with fewer valence electrons tend to form bonds to achieve stability. Understanding valence electrons helps explain why certain elements combine in specific ways to form molecules.

Valence electrons are the outermost electrons of an atom and play a crucial role in its chemical behavior. They determine how an atom can bond with others to form molecules. Atoms with the same number of valence electrons often exhibit similar properties and reactivity. For example, elements in the same column of the periodic table tend to react similarly because they have the same number of valence electrons. Understanding valence electrons helps explain why elements combine in certain ways to create the variety of substances we encounter in nature.
