CHE-Ch 7 Vocab (Ionic Compounds & Metals)

Front

Mixture of elements with metallic properties; forms when elements are similar in size or one is much smaller than the other.

Back

alloy

Front

Ion with a negative charge

Back

anion

Front

Ion with a positive charge.

Back

cation

Front

Force holding atoms together; formed by attraction of positive and negative ions or by electron sharing.

Back

chemical bond

Front

3-D arrangement of particles where positive ions are surrounded by negative ions and vice versa; varies in shape due to ion sizes and numbers.

Back

crystal lattice

Front

Electrons in metallic bonding that move freely between atoms.

Back

delocalized electron

Front

Ionic compound in aqueous solution that conducts electricity.

Back

electrolyte

Front

Metal atoms in a solid contribute valence electrons to form a "sea" of electrons, explaining malleability, conduction, and ductility.

Back

electron sea model

Front

Simplest ratio of ions in an ionic compound.

Back

formula unit

Front

Electrostatic force holding oppositely charged particles in an ionic compound.

Back
