Front 4

What does the atomic number tell you?

Back 4

The numbers of protons and the number of electrons of an atom.

Front 5

What does the atomic mass tell you?

Back 5

it tells you the mass of the atom and also tells the number of protons

and neutrons there are when added together

Front 6

which atom has 1 proton

Back 6

hydrogen

Front 7

if the atomic number is 14 and the mass is 29 how many neutrons do i have

Back 7

15

Front 8

Where is the nucleus located at?

Back 8

the center of an atom

Front 9

Where is the majority of the mass of an atom located at?

Back 9

In the nucleus

Front 10

What do groups tell you and which directions do they go on a periodic table?

Back 10

groups go up and down , tell you the number of valence electrons and determine the reactivity of an atom

Front 11

What are valence electrons?

Back 11

The number of electrons on the outermost shell of an atom

Front 12

Which groups are the most reactive? Why

Back 12

1 and 7

1 has to lose one electron while 7 has to gain 1 more

Front 13

Which group is inert and why

Back 13

Group 8 its has a full valence electron

Front 14

what element is in group 8 period 2

Back 14

neon

Front 15

What are period s on the periodic table and what do they tell you

Back 15

Periods are the rows and they tell you how many energy levels the atoms have

Front 16

How do you determine the reactivity of an atom

Back 16

By seeing how many valence electrons an atom has.

Front 17

Which subatomic particle determines the identity of an atom?

Back 17

protons

Front 18

If we change the number of electrons of an atom does it become a different atom?

Back 18

No because you still have the same number of protons.

Front 19

What are 5 indicators that a chemical reactions has occurred?

Back 19

1-flash of light

2-color change

3-temperature change

4-formation of a precipitate

5-has formation

Front 20

Is breaking a stick a physical or a chemical change ?

Back 20

physical

Front 21

milk souring a physical change or chemical change

Back 21

chemical

Front 22

The law of conservation of mass states...

Back 22

matter can not be created nor destroyed

Front 23

What is an unbalanced force?

Back 23

A force that causes an object to change its motion .

Front 24

what is a balanced force?

Back 24

forces acting on an object that have it keep its currency motion. Sitting still or constant speed

Front 25

what is speed

Back 25

distance traveled over a period of time. 45 mph

Front 26

what is velocity?

Back 26

distance traveled over a period of time with the direction associated to it. 45 miles per per hour west

Front 27

what is acceleration?

Back 27

speeding up slowing down or changing direction

Front 28

what is newtons first law?

Back 28

an object in motion will stay in motion and object at rest will stay at rest until an unbalanced force acts upon it.

Front 29

and example of newtons first law is?

Back 29

if you're riding in your vehicle, slam on the brakes, everything inside the vehicle will keep going forward

Front 30

what is newton's second law?

Back 30

force=mass x acceleration

f=ma

Front 31

Force=20 N mass =5kg what is the acceleration?

Back 31

4

Front 32

what are the characteristics of low pressure

Back 32

warmer weather and stormy conditions

Front 33

how do you fronts occur?

Back 33

fronts occur in association with the air circulation around low pressure air masses where portions of air with different temperatures and pressures are drawn toward the low. The interaction between air masses with different properties for my front the front is a line of contact at ground level mark into the boundary between the two air masses

Front 34

how is wind form?

Back 34

due to the unequal heating of the earth surface which causes different areas of pressure which creates wind

Front 35

what role do oceans play of the transferring of the suns energy?

Back 35

The oceans are able to hold more energy than the land. Oceans and move that energy all around the earth which affects the climate.

Front 36

mass=15,acceleration=3 what is the force

Back 36

45

Front 37

what is newton's third law?

Back 37

for every action there is a reaction

Front 38

if I jump to the west off of a boat which direction will the boat move?

Back 38

east

Front 39

what is convection?

Back 39

The process of warm air/water rising in cold air/water stinking. This also creates wind

Front 40

what is conduction?

Back 40

The transfer of heat through direct contact

Front 41

what is radiation?

Back 41

The transfer of heat through waves

Front 42

what is Land breeze and how does it work?

Back 42

land breeze happens at night time. This happens because the land cools off faster that the water causing a convection current that has it air rising over the ocean, sinking over the land

Front 43

what is seabreeze and how does it work?

Back 43

Seabreeze happens during the day this happens because the land is warmer than the ocean causing a convection current of the air over the land to rise in the air over the water to sink

Front 44

what are the characteristics of high-pressure?

Back 44

clear skies and cooler temperatures.
