Which ion formation takes more energy: K+ or Li+?

Li⁺

Explanation:

In ion formation, the ionization energy plays a very important role. To form an ion, an atom will lose or gain an electron to become charged.

The higher the ionization energy of an atom, the more the energy required to remove an electron from it to form an ion.

Generally, down the group, ionization energy decreases. Since both potassium and lithium are in group 1, Li will have a higher ionization energy. It will take more energy to form Li⁺ compared to K⁺.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
