Out of carbon and fluorine and hydrogen and nitrogen and aluminum which element has the highest value for the first ionization energy?
Fluorine. Ionization energies are a periodic trend and they generally increase as you go up and to the right in the periodic table.See the chart in the Web Links to the left for a complete chart of the ionization energies of all the elements.
Elements that have the highest first ionization energy?
Helium (He) has the highest first ionization energy. Ionization energy increase as you go across the periodic table from left to right
Which element has got the highest ionisation potential in the periodic table?
Nitrogen has the highest first Ionization potential.
What elements have the highest and lowest ionization energy?
Helium has the highest first ionization energy and francium has the lowest first ionization energy.
Which group of elements has very high ionization energies and very low electron affinities?
Group 8 (noble gases) have the highest first ionization energy because they are already stable and don't want to lose any electrons. Ignoring the noble gases, however, group 7 halogens (F, Cl, Br, I, etc.) have the highest first ionization energy. That's because these elements have seven valence electrons, and they don't want to give up any electrons - they want another one!
What group on the periodic table has the highest ionization energies?
Halogens

Helium (He) has the highest first ionization energy. Ionization energy increase as you go across the periodic table from left to right
What has the highest ionization energies?
Helium.
Which elements has the highest ionization energy?
Helium (He) has the highest ionization energy, then Neon (Ne) Ionization energy increases as you go across a period from left to right. Ionization energy decreases as you go down a group. Therefore, elements in the upper right of the periodic table have the highest ionization energy.
Has largerst ionization energy in its period?
Ionisation energies GENERALLY increase across a period. As a result, the noble elements (i.e. Group 0 elements) usually have the highest ionisation energies, as they are highly stable.
What element in period 3 has the highest second ionization energy?
Fluorine because it is the furthest right on the periodic table. Do no include noble gases in energies.
Which element has got the highest ionisation potential in the periodic table?
Nitrogen has the highest first Ionization potential.
What elements on the periodic table have the highest energies?
Group 18 as they have completely filled electronic configurations, are stable and hence do not ionize.
What element has the highest ionization energy in group 4 of the periodic table?
the nobles gases are the greatest ionization group
What elements have the highest and lowest ionization energy?
Helium has the highest first ionization energy and francium has the lowest first ionization energy.
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.
