What has the first largest ionization energy?
Helium has the highest ionization energy.
Does magnesium have a greater first ionization energy than strontium?
About twice as large, which is not that much at the first ionization level. Still, Magnesium has a slightly larger, one proton nucleus and one more electron in that valence level to add to the energy needed to pill the first electron out of it's orbital. Electron shielding may have something to do with this also as the other valance electron of this 2+ element may shield the pulled electron.
What is fluorine's ionization energy?
The first ionization energy is 1681 kJ/mol.
Whose first ionization energy is higher oxygen or carbon?
The first ionization energy for carbon is 1 086,5 kJ/mol. The first ionization energy for oxygen is 1 319,9 kJ/mol.
How does the first ionization energy change going down and across the periodic table?
In a group the first ionization energy decrease going down.In a period the first ionization energy increase from left to right.
What elements has the lowest first ionization energy Phosphorus scandium strontium or oxygen?
strontium
What has the first largest ionization energy?
Helium has the highest ionization energy.
What elements has the highest first ionization energy out of strontium magnesium beryllium calcium?
Beryllium will have the highest. Down a group ionization energy decreases.

Which element has a smaller ionization energy Cs or Sr?
Caesium has a smaller ionization energy (375,7 kJ/mol) than strontium (549,5 kJ/mol).
What elements have the smallest value for first ionization energy?
Francium has the lowest 1st ionization energy. It badly wants to lose that electron. It is extremely energetically favorable. Basically the elements that are in group 1 and are in the lowest periods.
What elements have the highest and lowest ionization energy?
Helium has the highest first ionization energy and francium has the lowest first ionization energy.
Do nonmetals have a low first ionization energy?
No. Nonmetals have a high first ionization energy.
What is first ionization energy?
Sodium's first ionization energy is 495 kJ / mol.
What elements has the highest first ionization energy?
Fluorine has the largest first ionization energy among the halogens.
What element has largest first ionization energy?
Helium has the highest ionization energy.
What is fluorine's ionization energy?
The first ionization energy is 1681 kJ/mol.
