Chapter 3 - Ionic Bonding

Question 1

define ionic bonding

Answer 1

a type of chemical, intra-molecular bonding where electrons from a metal are given to a non-metal, therefore holding the newly formed cation and anion together by electrostatic attraction.

Question 2

what is intramolecular bonding

Answer 2

bonding between atoms in a molecule

Question 3

what is intermolecular bonding

Answer 3

bonding and attraction between molecules of a substance

Question 4

what does the octet rule state?

Answer 4

the octet rule states that atoms are more stable when they have a valence shell of eight electrons.

Question 5

ionic bonding occurs primarily to satisfy the…

Answer 5

octet rule

Question 6

when the octet rule is satisfied, compounds replicate the…

Answer 6

noble gases

Question 7

what is a lattice?

Answer 7

a repeating, 3 dimensional pattern/arrangement of molecules. The ionic compound is like an empirical formula. it shows how many atoms are in the molecule but not in the total lattice.

Question 8

lattices are found in…

Answer 8

metals and other crystalline solids

Question 9

what is a polyatomic ion?

Answer 9

a group of tightly bound atoms that behaves as a single unit and carries an overall charge.

Question 10

When discussing transition metals, you must always include the…

Answer 10

roman numerals to show the charge

Question 11

what is the acronym for properties of ionic compounds?

Answer 11

cute
people
never can
have 
dirty water
embryo

Question 12

what does the acronym stand for?

Answer 12

cute-  crystalline
people-  high points
never can-  no conduction as a solid
have-  hard
dirty water-  dissolve in water
embryo- EM.B- electricity when molten and brittle

Question 13

why are ionic compounds crystalline solids?

Answer 13

due to the arrangement of ions in repeating 3D patterns

Question 14

why do ionic compounds have high points

Answer 14

as a large amount of energy is needed to separate the immobile cations and anions

Question 15

why do ionic compounds not conduct electricity in solid state

Answer 15

as there are no mobile particles to carry an electrical current

Question 16

why are ionic compounds hard

Answer 16

as the strong electrostatic attraction between anions and cations holds molecules closely together

Question 17

why do some ionic compounds dissolve in water

Answer 17

because polar water molecules can attract the charged particles and pull it apart

Question 18

why do ionic compounds conduct electricity when molten?

Answer 18

as ions can slide past each other and carry an electric current

Question 19

why do ionic compounds conduct electricity in aqueous state

Answer 19

in water, ions dissociate from the lattice and can conduct a current while moving freely.

Question 20

why are ionic compounds brittle

Answer 20

as the ions are so tightly packed together, when like charges are forced near one another they will repel and ultimately shatter the crystal.

Question 28

how to name ionic compounds

Answer 28

1. name the metal first using its full name

2. name the non-metal second using a suffix

ate is the largest value of oxygen

Question 30

ite

Answer 30

ite is the second largest value of oxygen
