Nov 21, 2023 · An ion is an atom or molecule that is charged due to a difference in number of electrons and protons. An anion has more electrons and is negatively charged; a cation is positively charge because ...
Ion Sizes. Cations are smaller than the original atom - consider how the sodium atom has electrons in three shells, while the sodium ion has electrons in only two shells. With more electrons, anions are larger than the original atom. Ion sizes are measured by the ionic radius. Ionic Radii in Picometers
ION meaning: 1. an atom or small group of atoms that has an electrical charge because it has added or lost one…. Learn more.
Ión (častica) Ión je elektricky nabitá častica, ktorá vzniká z elektricky neutrálneho atómu alebo molekuly pridaním resp. ubraním elektrónov pri ponechaní pôvodného počtu protónov . Ak atóm odovzdá elektrón, stáva sa katiónom (kladným iónom). Ak je počet elektrónov vyšší ako počet protónov, atóm sa mení na ...
Aluminum and carbon react to form an ionic compound. Predict which forms an anion, which forms a cation, and the charges of each ion. Write the symbol for each ion and name them. Answer. Al will form a cation with a charge of 3+: Al 3 +, an aluminum ion. Carbon will form an anion with a charge of 4−: C 4−, a carbide ion.

Sodium chloride is an ionic compound made up of sodium ions and chloride ions in a crystal lattice. Image credit: Wikipedia Commons, public domain. Atoms are electrically neutral because the number of protons, which carry a 1+ charge, in the nucleus of an atom is equal to the number of electrons, which carry a 1- charge, in the atom.
