631 kJ mol-1
Fluorine has the largest first ionization energy among the halogens.
The first ionization energy of germanium is 7.9 electron volts (eV).
Carbon (C) has a higher first ionization energy than silicon (Si). This is because as you move across a period in the periodic table, the first ionization energy generally increases due to increasing nuclear charge pulling electrons closer. Silicon is positioned to the right of carbon in the same period, resulting in a lower first ionization energy compared to carbon.
Sodium (Na) has the lowest first ionization energy in period 3.
The first ionization energy of nitrogen is 1402.3 kJ/mol.
strontium
Sodium's first ionization energy is 495 kJ / mol.
Helium has the highest ionization energy.
The first ionization energy is 1681 kJ/mol.
Fluorine has the largest first ionization energy among the halogens.
Fluorine has the largest first ionization energy among the halogens.
