Antimony. The higher an element is in a group, the smaller it is, requiring more energy (ionization energy) to remove an electron.
i could be wrong buy i believe tellurium
The ionization energy (first) of einsteinium is 619 kJ/mol.
low ionization energy
15.759
7.81 eV
mercury
This value is 869,3 kJ/mol.
potassium is greater in the second ionization energy.
Beryllium has greater ionization energy, with 899 kJ/mol versus Germanium's 762 kJ/mol. The general trend (most prominently displayed in the representative elements) in the periodic table is increasing ionization energy across a period, and decreasing ionization energy down a group.
It takes more energy to knock off two electrons
First ionization energy is the energy required to remove the first outermost electron from an atom. The second ionization energy is the energy required to remove the next available electron, and is greater than the first IE. The third IE is that energy needed to remove the third electron, and is greater the the second IE.
sodium because it's the first group and first group are the most
Lithium
First ionization energy is the energy required to remove the first outermost electron from an atom. The second ionization energy is the energy required to remove the next available electron, and is greater than the first IE. The third IE is that energy needed to remove the third electron, and is greater the the second IE.
because it lower than Ba as you go down ionization energy increases
ionization potential energy. but remember the atom must be neutral .
Helium (He) has the highest ionization energy.
No fire is not an ionization energy
