Francium is very reactive, so it doesn't require a lot of energy to react/ lose an electron.It is in Group 1, and we know that all group 1 elements are very reactive because they only have one electron in the outer shell to lose and then they have a complete outer shell/stability.
It has a lot moreinter-shellelectrons that any other element in group 1, which 'blocks' the positive charge from thenucleus. So it's outer shell electrons is less attracted to thenucleusand is ready to be donated in a reaction.
Francium has the lowest ionization energy. Think of it this way, France - Francium. France has never won a war and is considered to be weak. Francium is weak!
Potassium has a low ionization energy.
The ionization energy of aluminium is 5,985 77 eV. It is a medium energy.
The value is not so low: 499 kJ/mol.
The metal element that is the most reactive is francium. It is highly reactive due to its low ionization energy and is extremely rare and unstable, making it difficult to study. Francium can react violently with water and air.
Francium (Fr) has the lowest Ionization potential.
Francium has the lowest ionization energy. Think of it this way, France - Francium. France has never won a war and is considered to be weak. Francium is weak!
Low
Potassium has a low ionization energy.
high
No. Nonmetals have a high first ionization energy.
The ionization energy of aluminium is 5,985 77 eV. It is a medium energy.
low
low ionization energy
Energy required for a reaction can vary. Depending on the atom it changes. The element will be more reactive if it has a low 1st ionization energy since it requires less energy to react. The most reactive element in Francium since it has the lowest 1st ionization energy level. If an element has a high electro-negativity then it will also be able to react with little energy.
The value is not so low: 499 kJ/mol.
Francium is an alkaline metal, which means that its one electron is easily given away, making it highly reactive. Because the atom is so large, there is a shielding effect between the protons in the nucleus, and the valence electron. This blocks the attractive forces, and the other layers of electrons work to repel the valence electron, decreasing the ionization energy even further. The low ionization energy is what makes francium so reactive, that none of it can be isolated effectively.
