| Did you know that an atom is made of protons, neutrons and electrons? | |
 | |  |
|
 |
| | |
| Yes i do. Isn't the mass a whole number just like the number of protons there would be? | |
| | |
|

| Actually no. For example 4/2H atom haa a mass of 4.002 062amu. | |
| | |
|
|

|
|
|
| | |
| Because the difference between the mass of an atom and the sum of the masses of its protons, neutrons and electrons is the mass defect. | |

| | |
| This is to much for my brain to handle. I have to take notes. | |
