Chapter 7 Test - Ionic Compounds and Metals

a mixture of elements that has metallic properties; most commonly forms when the elements are either similar in size (substitutional alloy) or the atoms of one element are much smaller than the atoms of the other (interstitial alloy)

• alloy

• delocalized electrons

• electron sea model

• electrolyte

an ion that has a negative charge

• cation

• anion

• polyatomic ion

• monatomic ion

an ion that has a positive charge

• anion

• monatomic ion

• cation

• polyatomic ion

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

• ionic bond

• metallic bond

• electrolyte

• chemical bond

NGSS.HS-PS1-3

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

NGSS.HS-PS2-4

the electrons involved in metallic bonding that are free to move easily from one atom to the next throughout the metal and are not attached to a particular atom

• electron sea model

• delocalized electrons

• lattice energy

• oxyanion

an ionic compound whose aqueous solution conducts an electric current

• lattice energy

• electrolyte

• oxyanion

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
