Electron shells
| Question | Answer |
|---|---|
| what factors effect ionisation energy? | Atomic Radius, Nuclear charge and Electron sheilding |
| What is atomic radius? what effect does it have on ionisation energy required? | atomic radius is the distance of the electron from the nucleus. The greater the atomic radius the less attraction experienced by the outer electrons (less ionisation energy needed) |
| What is nuclear charge? what effect does it have on ionisation energy required? | nuclear charge is the charge of the nucleus (because of the protons. The greater the charge the more attraction felt by the electrons (more ionisation energy needed) |
| what is Electron sheilding? what effect does it have on ionisation energy required? | inner shells of electrons repel outer shells? the more electron shells the more electron shielding there is and the less ionisation energy is required to remove electrons |
| you are given a table of energy required for 8 ionisation numbers for an atom how do you tell which group it is in? | look for a large "jump" in energy required the ionisation number should tell you when it moves to a new shell (showing which group it's in) if there is no "jump" it will likely be in group 0 |
| What is first ionisation energy | the amount energy required to turn 1 mole of a gaseous atoms to turn it into a +1 ion |
