Kinetic molecular

Question 1

states of matter

Answer 1

solid liquid gas

Question 2

Brownian

Answer 2

random movement of particles

diffusion particles move from high concentration to low

Question 3

solid

Answer 3

occupies constant amount of space
define space and volume
held by fixed lattice
strong force of attraction

Question 4

lattice

Answer 4

arrangement of participles in a regular pattern

Question 5

liquid

Answer 5

occupies a constant amount of space

force of attraction weak particles freedom to move

Question 6

gas

Answer 6

occupies definite amount of space and volume

small force of attraction move freely

Question 7

freezing

Answer 7

temp at which a liquid becomes a solid

Question 8

melting

Answer 8

temp at which a solid becomes a liquid

Question 9

boiling

How does it change

Answer 9

temp at which a liquid becomes a gas

boiling point changes depending on atmosphere pressure changes w/ attitude

Question 10

evaporation

Answer 10

any temp
occurs on surface of liquid
no bubbles

Question 11

condensation

Answer 11

liquid formed from gas
opposite of evaporate
gas particles lose energy
no energy to stay gas

Question 12

sublimation

Answer 12

solid change to gas

substances with wear forces of attraction

Question 13

kinetic molecular theory

Answer 13

the force between molecules and the kinetic energy between them. particulates are in constant motion also forces of attraction strong between solid weak by gas

Question 14

assumptions

Answer 14

matter composed of small particles

particles are in constant motion

Question 15

solid molecule

Answer 15

vibration
strong force of attraction
least amount of kinetic energy

Question 16

liquid mole

Answer 16

flow over anther
moderate force of attraction
more kinetic energy

Question 17

gas mole

Answer 17

continue in straight line

kinetic energy stronger than attraction force

Question 18

Rutherford gold foil experiment

Answer 18

positive nucleus in center of atom

stuck thin sheets of gold foil w/alpha particles

Question 19

alpha particles

Answer 19

pass through between positive nuclei
deflected -close to nucleus
hit nucleus head on

Question 20

atom mass diameter

Answer 20

size depends on number of protons neutrons and electrons

Question 21

No.of protons in nuc

Answer 21

= atomic No.

Question 22

atomic No.

Answer 22

= above symbol

Question 23

mass No.

Answer 23

pro + neutrons (nucleus)

Question 24

isotopes

Answer 24

atoms that have the same atomic No. but different mass No. No. of protons cant change but No. of neutrons can change

Question 25

flame test

Answer 25

identify metal of action | flame color

Question 26

position

Answer 26

arranged in increase atomic No. valance indicated top column electrons in outer energy level group No. indicates No. of valance electrons

Question 27

row

Answer 27

energy level

Question 28

size of an atom

Answer 28

distance from nuc to boundary top to bottom radius increase No. of electrons increase

Question 29

atomic radius (up) energy levels (up)

Answer 29

left to right atomic radi dec bcz same energy level No. protons increase force of attraction are stronger electrons are closer to nucleus

Question 30

density of element

Answer 30

``` how many atoms are found in volume left to right increase metals decrease through non metals metals high density ```

Question 31

top to bottom

Answer 31

increase atomic radi and volume increase atoms get bigger cant pack more in same space as smaller atoms

Question 32

ionization energy of element

Answer 32

amount of energy to remove an element from neutral atom | indicate strength of atoms holding on to its electrons

Question 33

top to bottom

Answer 33

ionization energy decrease electrons are further away from nucleus atomic radius increase

Question 34

left to right

Answer 34

ionization energy increase atomic radi decrease difficult to break particles
