U1S1- Ionisation Energy Flashcards
1
Q
Nuclear charge
A
The more protons there are in the nucleus, the more positively charged the nucleus is and the stronger the attraction is for the electrons.
2
Q
Atomic radius
A
The greater the atomic radius, the less attracted the outer shell of electrons is to the nucleus.
3
Q
Sheilding
A
As the number of shells increase, the less attraction the electrons have to the nucleus.
4
Q
First ionisation energy
A
The first ionisation energy is the energy needed to remove 1 electron from each atom in 1 mole of gaseous atoms to form 1 mole of 1+ ions.
5
Q
Second ionisation energy
A
The energy needed to remove 1 mole of 1 electrons from 1 mole of gaseous ions to form 1 mole of 2+ ions.
