HideShow resource information
what is the first ionisation energy
the first ionisation energy is to remove 0ne mole of electron form its gaseous atom X= X+ + E-
1 of 5
what is the second ionisation energy
the second ionisation energy is to remove one mole of electrons from its gaseous unpositve ions X =X2+ + E-
2 of 5
what happens to the electrons in the outer shell and there ionisation energie
there is more sheliding the further away from the neclus wwhcih means less necleaur charge aon the electron and its less effective so its easier to loose the puter electron
3 of 5
why has oxygen got a higher ionisation energy thean nitrigen
nitrogen has enetered a new sub level and there is electron electrin repulsion
4 of 5
how many electrons in each sub shell
s shells
