Chemistry Ch. 7 Vocab and More

Chemical Bond

The forces that holds two atoms together

Cation

A positively Charged Ion

Anion

A negatively charged ion

Ionic Bond

The electrostatic force that holds oppositely charged particles together in an ionic compound.

Ionic Compound

Compounds that contain ionic bonds

Google: when metals and nonmetals bond through electron transfer. This process creates ions with opposite charges that attract each other. 

Crystal Latice:

A three dimensional geometric arrangement of particles.

Electrolyte

An invoice compound whose aqueous solution conducts electric current

Google: a substance that conducts electricity through the movement of ions, but not through the movement of electrons.

Lattice Energy

Energy is required to separate 1 mol of ions of an ionic compound.

Google: the energy required to convert one mole of an ionic solid into gaseous ionic constituents.

Formula Unit

The chemical formula for an ionic compoud; represents the smallest ratio of ions involved

Monatomic Ion

A one-atom ion that indicates the charges of common monatomic ions according to their location on the periodic table.

Google: a charged particle that consists of only one atom. The charge on the ion may be positive or negative.

Polyatomic Ions

Ions made up of more than one atom

Oxyanion

A polyatomic ion composed of an element, usually a nonmetal bonded to one or more oxygen atoms

Electron Sea Model

Proposes that all the metal atoms in a metallic solid contribute their valence electrons to form a “sea” of electrons.

Delocalized Electrons

Atoms that are free to move; atoms that move easily from one atom to the next

Metallic Bond

The attraction of a metallic cation for delocalized electrons

Google: a chemical bond that occurs between metal atoms. It's the primary type of bond that holds metals together. 

Alloy

A mixture of elements that has metallic properties..
