metal and metal
What is a metallic bond
100
a bond in which two atoms share one or more pairs of electrons, nonmetal and nonmetal
What is covalent bond
100
By the number of bonding pairs of electrons and the number of nonbonding or lone pairs around the central atom
How do you classify molecules
200
elements form compounds in order to have eight valence electrons
What is the octet rule
200
the lowest whole number ratio of the ions present in an ionic compound, an empirical formula.
What is formula unit
200
a mixture composed of two or more elements, at least one of which is a metal

300
the three-dimensional arrangement of atoms in a molecule

400
positive ions formed when an atom loses one or more electrons
What is a cation
400
crystal lattice high melting point hard but brittle conducts electricity when molten (melted) or dissolved in water

400
a pair of electrons in a Lewis electron-dot structure that is not shared between atoms
What is a lone pair
400
The total number of electron pairs, both bonding pairs and lone pairs
What is electron domain geometry
500
It shows bonding between atoms of a molecule and the lone pairs of electrons
What does the electron dot diagram show
500
a solid material that contains atoms or groups of atoms arranged in a orderly structure
What is a crystal lattice
500
delocalized valence electrons that hold the metal atoms in place
How are metallic bonds formed
500
diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule
What are Lewis electron dot structures
500
a model that predicts the geometry of individual molecules from the number of electron pairs surrounding their central atoms
