What is a proton |
A atom in the middle of the nuecules with a positive charge |
|
|
What is a neutron |
An atom in the nuecleus with no charge |
|
|
What is an electron |
An atom outside the nuecleus on the electron cloud with new mass and a negative charge |
|
|
What does the atomic mass tell you |
It tells you the mass of the atom and also |
|
|
If the atomic # is 14 and the mass is 29 how many neutrons do you have |
15 |
|
|
Where is the nuecleus |
In the center of an atom |
|
|
Where is the majority of the mass of an atom |
In the nuecleus |
|
|
What do groups tell you |
They tell you the number of valence electrons |
|
|
What are valence electrons |
The number of electrons |
|
|
Which group is the most reactive |
1 and 7 |
|
|
Which group is reactive |
Group 8 |
|
|
What element in group 8 and period 2 |
Neon |
|
|
What are periods on the periodic table and what do they tell you |
How many energy levels |
|
|
How do you determine the identity of an atom |
No because you still have the same number of protons |
|
|
The law conservation of mass states |
Matter can be neither created nor destroyed |
|
|
What is an unbalanced force |
Force acting on an object that have a keep up his current motion |
|
|
What is speed |
Distance traveled over appeared of time |
|
|
What is velocity |
Distance traveled over appeared of time with direction |
|
|
What is acceleration |
Speeding up slowing down or changing direction. |
|
|
What is Newton's first law |
An object in motion will stay in motion in an object at rest will stay at rest until an unbalanced force acts upon it |
|
|
An example of newtons first law is |
If you are riding in your vehicle slam on the brakes everything inside the vehicle keep moving forward |
|
|
What is Newton's second law |
Fourth equals mass times acceleration F =ma |
|
|
What is Newton's third law |
For every action there's an equal and opposite reaction |
|
|
If I jump to the west of the boat which direction will the boat move |
East |
|
|
What is convection |
The process of warm air/water raising and cool air/water sinking this also creates wind |
|
|
What is conduction |
The transfer of heat through direct contact |
|
|
What is radiation |
The transfer of heat through Waves |
|
|
What is a land breeze |
Land breeze happens at night time this happens because the land clothes off faster that the water causing a convection current has air rising over the ocean syncing over the land |
|
|
What is a land breeze |
Land breeze happens at night time this happens because the land clothes off faster that the water causing a convection current has air rising over the ocean syncing over the land |
|
|
What is a sea breeze |
Seabreeze happens during the day. This happens because the land is warmer than the ocean causing the convection current of the air over the land to rise in the air over the water to sync. |
