the first inoization energy is 2372.3 kJ mol-1 there are 6.0221415 × 10^23 in a mole from avagadros number, devide the ionization energy for one mole by the number of atoms in a mole and you get the first ionization energy for one atom.
Lithium has the least number of protons, rubidium has the most number of protons.
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.
Hydrogen is the first, smallest, and lightest element. It is number 1 in the periodic table of elements.
First stars made the smallest elements, from hydrogen up and progressively larger stars made progressively larger elements
Helium has the highest ionization energy.
Fluorine has the largest first ionization energy among the halogens.
Helium has the highest first ionization energy and francium has the lowest first ionization energy.
The first electron shell, or energy level only holds 2 electrons. It is the smallest and closest energy level to the atom's nucleus. Hydrogen and helium are the only two elements to have electrons in just the first shell.
T he smallest first ionization energyis for lithium.
