Web3 jul. 2024 · What Is an Ion? Ions are atoms with extra electrons or missing electrons. When an atom's outermost orbital gains or loses electrons (also known as valence electrons ), the atom forms an ion. An ion with more protons than electrons carries a net positive charge and is called a cation. WebBecause the charge and size of an ion directly affect the structure of ionic solids, it is crucial that you can correctly identify the cation and anion within an ionic compound, compare sizes between ions, and compare charges. We can quickly identify cations and anions based on the ionic compound name and formula. chittagong ftp server chittagong full movie watch online free
