fluorine
bromine
chlorine
The answer would definitely be Helium
Fluorine > Chlorine > Bromine
beryllium (Be)
Beryllium (Be)
what element C or N has the highest ionization energy
Fluorine has the largest first ionization energy among the halogens.
Helium (He) has the highest ionization energy.
Beryllium is the group 3A element with the highest ionization energy.
Helium (He) has the highest first ionization energy. Ionization energy increase as you go across the periodic table from left to right
what element C or N has the highest ionization energy
Helium has the highest ionization energy.
Helium has the highest ionization energy.
Carbon has the highest ionization energy
Fluorine has the largest first ionization energy among the halogens.
Helium (He) has the highest ionization energy.
Ionization energy decrease down the group.So in halogens,Fluorine has highest 1st ionization energy.
Krypton has a higher value.
the nobles gases are the greatest ionization group
xenon increases from left to right across periods (first ionization energy)
Beryllium is the group 3A element with the highest ionization energy.
Helium (He) has the highest first ionization energy. Ionization energy increase as you go across the periodic table from left to right
