Image:
Atom (binary/octet-stream)
|
proton, neutron and electron |
| Where are protons found in an atom? | protons are found in the nucleus of the atom |
| Where are electrons found in an atom? | electrons are found in the shells |
| Where are neutrons found in an atom? | Neutrons are found in the neucleus of the atom |
| What is the mass of a neutron? | the mass of a neutron is 1 |
| what is the mass of an electron? | the mass of an electron is 1/2000 |
| What is the mass of a proton | the mass of a proton is +1 |
| What is the charge on an electron? | Electrons have a negative charge (-1) |
| What is the charge on a proton | Protons have a positive charge (+!) |
| What is the charge on a neutron? | Neutrons are neutral and have no charge (0) |
| Which group are these elements found in and how can you tell? | They are all in group 1 because they have one electron in the outer shell. |
| Which group are these elements found n ? | They are found in group 0 because the full outer shell is full. |
| which group and period is this element found? | This element is found in group 4 (it has 4 electrons in the outer shell) and period 2 (it has 2 shells. |
| Which group and period is sodium found it? | It is in group 1 ( it has one electron in the outer shell). It is in period 3 ( it has 3 shells). |
| What is the name of the top number? What does it show? | The top number is called the ATOMIC MASS. It shows that lithium has 7 protons AND neutrons in the nucleus. |
| What is the name given the bottom number? What does it show? | The bottom number is the ATOMIC NUMBER. It shows the number of PROTONS in an atom. |
