|
What does the atomic number tell you? |
Number of protons and electrons in an atom
|
|
|

|
|
Where is the majority of the mass of an atom located at? |
In the nucleus |
|
|
What do groups tell you, which direction do they go in the periodic table |
Groups go up and down, they tell you the number of valence electrons and determines reactivity of atom |
|
|
What are valence electrons? |
The number of electrons on the outermost she'll of an atom |
|
|
Which groups are they most reactive? Why? |
1 and 7, 1 has to loose 1 more and 7 has to gain 1 more |
|
|
Which group is inert and why? |
Group 8 because it has full valence electrons |
|
|

Neon |
|
|
What are periods in the periodic table and what do they tell you? |
Periods are the rows and they tell you how much energy levels the atoms has |
|
|
Who do you determine the reactivity of an atom? |
By seeing how many valence electrons an atom has |
|

Protons |
|
|
If we change the number of electrons in an atom does it become a different atom? |
No because you will still have the same number of protons |

|
|
What is an unbalanced force? |
A force that causes an object to change its motion |
|
|
What is balanced force? |
Force acting on object that have it keep its current motion. still or constant speed |

What is velocity? |
Distance travels over a period of time with direction associated to it. 45mph west |
|
|
What is acceleration? |
Speeding up, slowing down or changing direction |
|
|
What is Newton's first law? |
An object in motion will stay in motion and an object at rest will stay at rest until an unbalanced force acts upon it. |
|
|
An example of newtons 1st law is? |
If you are riding in a vehicle, slam on the brakes, everything inside the vehicle will keep going forward |
|

What is radiation? |
The transfer of heat through waves |
|
|
What is a land breeze and how does it work |
Land breeze happens at night time. This happens because the land cools off faster than water causing a convection current that has air rising over the ocean, sinking over the land |
