Chemistry - Third Quarter Final Exam

Front

An ion that has a negative charge

Back

Anion

Front

An ion that has a positive charge

Back

cation

Front

the force that holds two atoms together; may form by the attraction of a positive ion for a negative ion or by the attraction of a positive nucleus for negative electrons

Back

chemical bond

Front

a three-dimensional geometric arrangement of particles in which each positive ion is surrounded by negative ions and each negative ion is surrounded by positive ions; vary in shape due to sizes and relative numbers of the ions bonded

Back

crystal lattice

Front

An ionic compound whose aqueous solution conducts an electric current.

Back

electrolyte

Front

Proposes that all metal atoms in a metallic solid contribute their valence electrons to form a "sea" of electrons, and can explain properties of metallic solids such as malleability, conduction, and ductility.

Back

electron sea model

Front

the simplest ratio of ions represented in an ionic compound

Back

formula unit

Front

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

Back

ionic bond

Front

The energy required to separate one mole of the ions of an ionic compound, which is directly related to the size of the ions bonded and is also affected by the charge of the ions.

Back

lattice energy

Front

An ion formed from only one atom.

Back

monatomic ion
