How successive ionization energies help us distinguish between core electrons and valence electrons?
Successive ionization energies to provide evidence for arrangement of electrons into core and valence
What is successive ionization energies?
The energy required to remove more than one electron from atoms. After the first electron is removed, there is now a positive charge which is working against removing another electron. So successive ionization energies increase.
Do an atom's successive ionization energies increase regularly?
No, an atom's successive ionization energies do not increase regularly. The first ionization energy, which is the energy required to remove the outermost electron, is typically lower than the second ionization energy, which is the energy required to remove the second electron. The ionization energies generally increase as more and more electrons are removed from an atom. However, there can be irregularities due to factors such as electron-electron repulsion and electron shielding.
How can the number of electrons in the outer main energy level of phosphorous be determined using the successive ionization energies?
As each electron is removed, the successive ionization energy values increase. However, the ionization energy increases a lot when the sixth electron is removed. This suggests that the sixth electron is removed from a shell which is closer to the nucleus.
What has the highest ionization energies?
Helium.
How does metallic character relate to first ionization energies?
we know that metal has tendency to lose a electron more easily than non metals so the value of the first ionization energy of the metals is very small.
Both Groups IA and IIA have what ionization?
They both have alkaline ionization energies.
Do noble gases have high ionization energies?
Yes they do
Can member of different groups have the same ionization energies?
no
Do halogens have high or low ionization energies?
no it does not
Ionization energies of oxygen and xenon same or not?
No, but they are similar.
What group on the periodic table has the highest ionization energies?
Halogens
