| Question | Answer |
| Atoms are a fundamental piece of matter. | 1
|
Everything is made of matter and therefore composed of atoms. | 2
| There are three particles inside of an atom-Proton,Electron,Neutron | 3
| Protons are positive (+) | 4
| Electrons are negative (-) | 5
| Neutrons are neutral (0) they have no charge | 6
| The nucleus is in the inside of the atom | 7
| The protons and neutrons are in the nucleus | 8
| The electron cloud is the space outside the nucleus | 9
| The electrons are in the cloud in shells or levels | 10
| The particles in the atom are weighed in amu’s | 11
| Protons and Neutrons each weigh around 1 amu | 12
| Electrons weigh 1/1836 of an amu!! | 13
| We will look at 3 levels or shells in the electron cloud | 14
| The 1st level can hold 2 electrons | 15
| The 2nd level can hold 8 electrons | 16
| The 3rd level can hold 8 electrons | 17
| In a neutral atom, you have the same number of protons and electrons. | 18
| To help you remember this think: APE | 19
| A is Atomic Number, found above the element symbol | 20
| P is Proton Number | 21
| E is Electron Number | 22
| To find neutrons think: MAN | 23
| M is for Mass Number (also called atomic mass) | 24
| A: Atomic Number | 25
| N is the number of neutrons | 26
| Subtract A from M to get neutrons | 27 |
