Want this question answered?
Bromine has the highest.
Bromine has because the ionization energy increases as you move across and decreases as you move down.
Krypton has a higher value.
yes because ionization energy increases up and to the left on the periodic table. and fluorine has the highest ionization energy because it is so close to becoming a noble gas it tears off electrons from everything to complete the octete
Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.
It's not...
The energy required to remove electron from atom are called ionization energy. Larger atom or molecule have lower ionization energy and molecule have higher ionization energy.
Ionization energy decrease down the group.So in halogens,Fluorine has highest 1st ionization energy.
Potassium has a higher ionization energy than cesium.
Br
The first ionization energy of neon is higher: 2 080,7 kJ/mol.
The first ionization energy for carbon is 1 086,5 kJ/mol. The first ionization energy for oxygen is 1 319,9 kJ/mol.
