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.
Why are nonmetals more likely to react with each other by sharing electron?
nonmetals have relativly high ionization energies. Nonmetals have relatively high ionization energies .
Why do noble gases not have listed ionization energies?
The noble gases of each period have the highest ionization energies in their periods. Refer to the related link to see a graph showing the ionization energies of the elements across each period.
What contributes to low ionization energy for an atom?
The fewer numbers of valence electrons, and the farther away those valence electrons are from the nucleus, the lower the ionization energy will be. So your group 1 and 2 metals toward the bottom of those groups will have low ionization energies, and therefore be very reactive.
Do noble gases have high ionization energies?
Yes they do
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.

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 do successive ionization energies relate to?
The energy required to remove more than one electron from atoms.
What is group trend in the first ionization energies?
Ionization energies decrease moving down a group, because the shielding effect reduces the pull of the nucleus on valence electrons. Making them easier to remove.
Why are nonmetals more likely to react with each other by sharing electron?
nonmetals have relativly high ionization energies. Nonmetals have relatively high ionization energies .
Would you expect metals or nonmetals in the same periods to have higher ionization energies?
Non-metals have higher ionization energies within the same period. This is because non-metals want to gain electrons to be able to be like the nearest noble gas.
The atoms of the most active non-metals have?
large atomic radii and low ionization energies
Why do noble gases not have listed ionization energies?
The noble gases of each period have the highest ionization energies in their periods. Refer to the related link to see a graph showing the ionization energies of the elements across each period.

What has the highest ionization energies?
Helium.
