Q
1st ionisation energy
A
The amount of energy required to remove the most loosly bound electron from a NEUTRAL GASEOUS atom in its GROUND STATE
1
Q
Atomic radi
A
Half the distance between the 2 nuclei of 2 atoms if the SAME element joint together by a SINGLE COVALENT bond
2
Q
2nd ionisation energy
A
Energy needed to remove an electron from a POSITIVELY CHARGED ION
3
Q
Electronegativity
A
RELATIVE ATTRACTION that an atom in a MOLECULE may have for a PAIR of SHARED electrons in a covalent bond
4
Q
Exceptions for ionisation energy rules
A
If the sublevels are full / half full (slight)
If electron to be removed is from a new shell (major)
