Bonding Test Review Sheet

Question 1

Reactants

Answer 1

compounds that go into a chemical reaction

Question 2

Covalent Bonds

Answer 2

joint atoms inside a molecule

Question 3

Chemical Bonds

Answer 3

can be either ionic or covalent

Question 4

Ions

Answer 4

stay together because atoms that make them up are oppositely charged, behave differently than atoms

Question 5

Single Bond

Answer 5

occurs when each atom donates only one electron to a bond, more flexible and easy to break

Question 6

Positive Ions

Answer 6

give up electrons to other atoms

Question 7

Ionic Bonds

Answer 7

where all electrons are transferred from one atom to another, all salts have them

Question 8

Answer 8

a molecular formula

Question 9

Compound

Answer 9

two or more atoms combined in a certain ratio

Question 10

accounts for all the atoms in a chemical reaction

Question 11

Products

Answer 11

compounds that are made during a chemical reaction

Question 12

Octet Rule

Answer 12

states all atoms must have 8 electrons in their outermost energy level

Question 13

Molecular Formula

Answer 13

tells you the composition of a molecule

Question 14

Answer 14

when atoms share electrons

Question 15

Molecular Formula

Answer 15

tells you the composition of a molecule or compound and the arrangement of the atoms

Question 16

Difference between atom and ion

Answer 16

atoms have no charge, ions have charge

Question 17

Difference between covalent bond and ionic bond

Answer 17

covalent bonds form when 2 or more atoms share electrons while ionic bonds form when one atom transfers electrons to another atom
