CHM--Vocabulary Notes--Chemistry Ionic, Metallic, and Covalent Bonds

Sharing specifically 6 electrons.

Shows the kinds and numbers of atoms in the smallest representative unit of a substance.

Sharing specifically single pair of electrons.

Electrons in the highest occupied energy level of an element’s atom.

The ions formed when atoms of chlorine and other halogens gain electrons.

Chemical formula of a molecular compound.

When atoms are held together by sharing electrons.

Consisting of 2 atoms of the same element. Exist in pairs instead of individual atoms.

The lowest whole-number ratio of ions in an ionic compound.

Bond where the electrons are shared unequally. One atom to gain a slight negative charge.

The attraction of the free-floating valence electrons for the positively charged metal ions.

Sharing specifically 4 electrons.

A compound composed of molecules.

When forming compounds, atoms tend to achieve the electron configuration of a noble gas.

Compounds composed of cations and anions. Held together by electrostatic charges.

Mixtures composed of two or more elements, at least one of which is a metal.

Representations that show valence electrons.

The ion formed when an atom loses valence electrons.

Compounds composed of cations and anions.

Valence electrons that are not shared between atoms, affecting the geometry of the molecule.

The electrostatic forces that hold ions together in compounds that transfer electrons.

The "magic" number in chemistry:

Shows the kinds and numbers of atoms in the smallest representative unit of a substance.

The number of ions of opposite charge that surround the ion in a crystal.

The ion formed when an atom gains valence electrons.
