Ionisation Energy
Flashcards do conjunto (7)
- 1What is the first ionisation energy?The energy required to remove the most loosely held electron from one mole of gaseous atoms to produce 1 mole of gaseous ions each with a charge of 1+
- 2What is the equation definition of first ionisation energy?+ -
(X) --> (X) + e
(g) (g) - 3What does X mean?It is the element being used in the first ionisation
- 4What are the factors that affect Ionisation Energy?Proton Number
&
Shielding/Shells - 5How does proton number affect the ionisation energy?The greater the proton number, the greater the attraction
- 6How does amount of shielding/shells affect the ionisation energy?More shells, more repulsion, less attraction
This is stronger than the proton number - 7What is nuclear attraction?A summary of the overall attraction to the nucleus after the shielding and proton number is taken into account
