Protons |
Relative mass:1 Relative charge:+ |
|
|
Electron |
Orbits the nucleus Make up most of the volume Relative mass:1/2000 Relative charge:- |
|
|
Neutron |
Relative mass:1 Relative charge:0 |
|
|
Mass number |
A Number of protons + neutrons |
|
|
Atomic number |
Z Number of protons |
|
|
Atoms |
All elements are made from atoms No overall charge since no of electrons =protons |
|
|
Ions |
Formed by gaining and losing electrons Negative ion=more electrons Positive ion=less electrons |
|
|
Isotopes |
Elements with the same no of protons but different no of neutrons No difference in chemical properties as isotopes have the same electronic arrangement Physical properties as it depends on the mass of an atom |
