Chapter 8: Ionic Compounds

Question 1

alloy

Answer 1

p. 230 a mixture of elements that has metallic properties

Question 2

anion

Answer 2

p. 214 a (-) ion

Question 3

cation

Answer 3

p. 212 a (+) ion

Question 4

chemical bond

Answer 4

p. 211 The force that holds two atoms together.

Question 5

delocalized electrons

Answer 5

p. 228 Electrons that are free to move because they are not held by any specific atom and can move easily from one atom to the next.

Question 6

electrolyte

Answer 6

p. 218 An ionic compound whose aqueous solution conducts and electric current.

Question 7

What is the electron sea model and what can you learn from it?

Answer 7

p. 228 It proposes that all the metal atoms in a metallic solid contribute their valence electrons to form a “sea” of electrons

Question 8

formula unit

Answer 8

p. 221 The simplest ratio of the ions represented in an ionic compound.

Question 9

ionic bond

Answer 9

p. 215 The electrostatic force that holds oppositely charged particles together in an ionic compound.

Question 10

lattice energy

Answer 10

p. 219 The energy required to separate one mole of the ions of an ionic compound.

Question 11

metallic bond

Answer 11

p. 228 the attraction of a metallic cation for delocalized electrons

Question 12

monoatomic ion

Answer 12

p. 221 A one-atom only ion, such as Mg 2+ or Br-.

Question 13

oxidation number

Answer 13

p. 222 The charge of a monoatomic ion.

Question 14

oxyanion

Answer 14

p. 225 A polyatomic ion composed of an element, usually a nonmetal, bonded to one or more oxygen atoms. Ex: nitrate, nitrite, sulfate, sulfite

The ion with more O atoms -ate
Ion with fewer O atoms -ite

Question 15

polyatomic ion

Answer 15

p. 224 Ions made up of more than one atom. (learn common polyatomic atoms from chart!!)
