What is the group trend for the ionization energy for the alkali metals?
As you go down the group (any group), ionization energy decreases. So in terms of ionization energy, for the alkali metals, Lithium > Sodium > Potassium > Rubidium > Caesium > Francium
What is the relationship between ionization energy and the alkali metals?
There is no relation ship. They have the lowest ionization energies.
What Alkali metal has the highest ionization energy?
lithium
Why do alkali metals have lower ionization potentials than alkaline earth metals?
Noble gases have the highest ionization energies of the elements because they don't "want" to lose any electrons. All atoms strive to have a full outer shell like the noble gases and once they reach their equilibrium, it takes a lot of energy to rip off another electron. Alkali metals, by comparison, have a large atomic radius in their period --> low electronegativity --> low ionization energy. Alkali metals have relatively large atomic radii, which means the nucleus is farther away from the electrons than in an atom with a small atomic radius. Because the electrons are far away, it is easier to rip an electron. If it is easy to take away an electron from an atom, then it has a low ionization energy. Alkali metals have lower first ionization energy than noble gases.
What element in family IA has the lowest ionization energy?
the lowest ionization energy in IA :hydrogen ,lithiun ,sodium and potassium
Why do the alkali metal have lower ionization energies than the alkaline earth metals?
Alkali gases only have 1 electron needing to be removed to reach a stable noble gas configuration. Alkaline earths have two electrons. Alkali metals thus have the lower ionization energy of the two groups.
Alkali metal and alkaline earth metal have how many ionization energies?
Alkali metals (group 1 elements) have one valence electron. Hence have one ionization energy Alkaline earth metals (group 2 elements) have two valence electron. Hence have two ionization energy

Is lithium behaves different from the other alkali metals true or false?
True. Although lithium is an alkali metal it is quite different from the other alkali metals. In fact it can generally behave more like an alkaline earth metal, such as Magnesium (Mg), Calcium (Ca) Strontium (Sr) and Barium (Ba). One of the major characteristics of the alkali metals is their low ionization energy, which is why lithium can easily be present in its ionic form of Li+. However, lithium posses the highest ionization energy of the alkali metals
Why alkali metal have low ionization energy?
Ionization energy is the energy required to remove an electron from an atom or ion. Low ionization energy indicates that it takes less energy to remove an electron from the atom. The alkali metals are in Group I on the Periodic Table. This indicates that their atoms have only one electron (out of a possible eight) in their outermost energy level. Therefore it takes less energy to remove the single outermost electron. Moving across a period on the Periodic Table, ionization energies increase because there are more and more electrons in the outermost energy level, requiring more energy to remove an electron.
Which element has a smaller ionization energy Cs or Sr?
Caesium has a smaller ionization energy (375,7 kJ/mol) than strontium (549,5 kJ/mol).
