Atoms become electrically charge when they reacting to one another. The two groups of charged atoms are cations (positively charged) and anions (negatively charged), and all together these types of atoms are called ions. The ability to become electrically charge depends on their electronegativity values and ionization energies. Electronegativity refers to an atom's "pull" on electrons, meaning that the more electronegative an atom is the harder it will "pull" on electrons from other atoms. The more electronegative atoms (typically the anions) reside on the far right side of the Periodic Table. Ionization energy refers to the energy needed to pluck an electron from an atom. Atoms with the lower energy typically have lower electronegativity values, making them cations (which are to the left of the periodic table).
Anion/Anions.
Ions. Usually negative ions, but not always.
A Polyatomic ion is a covalently bonded group of atoms that has a positive or negative charge and acts as a unit
An ion is an atom or group of atoms that has an electrical charge from having either gained or lost electrons. An ion may have either a positive or a negative charge. An electron is a subatomic particle that carries a negative charge and is usually found in the orbitals of atoms and ions.
A polyatomic ion is held together by covalent bonds between atoms. They can be either positive or negative. For example, the ammonium ion, NH4+, has a positive charge, and the sulfate ion, SO42-, has a negative charge.
When an atom or group of atoms becomes electrically charged, it is referred to as an ion. If it has a positive charge (+) it is called a cation, and if it has a negative charge (-), it is called an anion.
a charged group of two or more nonmedal atoms is called a?

Electrically charged atoms are known as ions. Ions occur when an atom looses or gains electrons. A normal atom is neutral, because it has the same number of positive protons and negative neutrons. When electrons are lost or gained, the atom can become positive (a cation) or negative (an anion). When an atom is positeve or negative, it is electrically charged.
Zero. (Ions have charge; atoms are always neutral.)
molecules
an electrically neutral group of two or more atoms held together by chemical bonds.
A polyatomic ion is a group of atoms with a charge.
Ions are formed when atoms have charges. Cations are species with positive charge. Anions are species with negative charge.
they are the cations
