1

“Strength”

extent to which acids and bases ionize

2

Ionize

produce or become ions

3

Concentration

measure of how many solute particles are dissolved in a solvent

4

Autoionization

reaction of a chemical w/ itself to produce positive and negative ions by the dissociation of one molecule

5

Neutralization reactions

double displacement reaction between an acid and a salt base, usually to form water and an ionic compound (salt)

6

Buffers

function is to maintain or resist changes in pH

7

Radioisotopes

isotopes with unstable nuclei

8

Nuclear equation

shows the change from the initial nucleus (reactant) to final nucleus (product) + any other particles formed

9

Rate of disintegration of radioisotopes

amount breaking down per second

10

Amount of radiation absorbed

amount of radiation absorbed per g of material (or tissue)

11

Equivalent dose

measure of the biological effect of different types of radiation

12

Equivalent Dose Formula

rem= rad (Factor)

13

Hydrocarbon

molecule mostly composed of H and C

14

Combustion

hydrocarbons don’t react easily at room temperature but BURN EASILY

15

Hydrogenation

adding H atoms to the two F atoms in a double bond

16

Polymers

long chains of repeating molecules joined together

17

“-mer”

multi-carbon, molecular unit

18

Alcohol

contains an –OH (hydroxyl) group

19

Ether

contains an O atoms between two C atoms

20

Aldehyde

has a carbonyl C atom bonded to a long H atom

21

Ketone

has a carbonyl C atom bonded to two C atoms

22

Carboxylic acid

has a carbonyl C atom bonded to an –OH group

23

Ester

has a carbonyl C atom bonded to an O atom bonded to another C chain

24

Amine

compound where a N atom is attached to one or more C atoms

25

Amide

compound with a carbonyl group attached to a N atom

26

Thiol

alcohol with a S in place of the O

27

Thioether

ether with a S in place of the O

28

Zwitterion

a single molecule with both a negative and positive change within it (proteins, amino acids)

29

“R-groups”

indicates the properties of the amino acid when it’s in a protein

30

Acid formulas:

Begin with H+
