A computer analysis gives data for particles in two regions of an atom.
| region | particle | number of particles | relative mass of each particle | relative charge of each particle |
|---|---|---|---|---|
| central | proton | 7 | 1 | +1 |
| central | neutron | 8 | 1 | 0 |
| surrounding | electron | 7 | 11840\dfrac{1}{1840}18401 | -1 |
Describe the distribution of mass and charge in this atom.
Use values from the table in your answer.
One electron is removed from the surrounding region.
Describe how this changes the combined relative mass and the overall relative charge.
