###### Asked in Energy

### Why second ionisation energy is larger than the first ionisation energy?

Take Sodium for an example:
The first ionisation energy for sodium is small, while the
second is very large. The electron arrangement for Sodium is 2)8)1)
so the first ionisation energy removes the first outer electron
leaving a stable electron arrangement of 2)8). The electrons are
now closer to the nucleus so the attraction is larger, increasing
the energy needed to take another electron away. Because there is
one less electron, this will mean an increase in nuclear attraction
for the remaining electrons.

###### Asked in Elements and Compounds

### Why carbons first ionisation energy is greater than boron's first ionisation energy whereas its reverse is true for second ionisation energy?

this is simply by the energy needed for the outer electron of
boron is less than the energy for carbons outer electron. most
elements which change shell will have a sudden decrease which then
the factor of extra shielding decreases the attraction of the
electron and the center of the atom.
