Nucleus |
|
|
Is a Nucleus tightly packed or loosely packed? |
Tightly packed |
|
|
Are electrons, protons and neutrons all the same size? |
No, Electrons are smaller than protons and neutrons |
|
|
If an atom has 25 protons, how many electrons does it have? |
25 |
|
|
How do you get the number of neutrons? |

|
|
What was first discovered in atoms? |
The particle theory -Simplistic model -All atoms are made from particles -Particles are always moving -Every substance has its own particle |
|
|
What did Dalton's model explain? |
-Particles are indestructible -Particles cannot be seperated -Atoms were solid spheres |
|
|
What did Thompson figure out? |
-Atoms contain electrons, protons and neutrons -Muffin model |
|
|
What did Rutherford find? |
-Electrons orbit around the nucleus -Protons and neutrons are tightly packed in the center (nucleus) |
|
|
What did Bohr add? |
-Electrons are not involved with the protons and neutrons because they are orbiting on fixed circuits around the nucleus |
