1st ionization energy is the energy to remove one electron from a neutral atom. 2nd ionization energy is the energy to remove an electron from a positively charged ion. When this is done there is a stronger attraction for electrons in the ion than in the neutral atom because there is one less electron to 'interfere' with the electron being removed.

∙ 8y agoFor all chemical elements the first ionization energy has a lower value; the energy increase from exterior to interior because the attraction between the nucleus and electrons is higher.

∙ 13y agoThe outer electron for lithium is in the next sub-shell (s sub shell) which is further from the nucleus, so the electron is less attracted to the nucleus and is more easily removed.

Which element has a lower first ionization energy than aluminum (Al)?
As an example potassium has a lower first ionization energy than aluminum (Al).
Which element has a lower 1st ionization energy than aluminum?
The first level ionization energy oif aluminium is 577,5 kJ/mol.All alkali metals have lower values for the ionization energy.
Does calcium have a lower first ionization energy level than sodium?
No. Calcium has TWO valence electrons, and Sodium has ONE. It is lot easier to take off one, than two you see. However, the second ionization energy of calcium IS however than the second ionization energy of Sodium. ;)
Why is it easier to lose electrons from a cesium atom than from a lithium atom?
It all has to due with ionization energy. Ionization energy is the energy required to remove an electron from an atom to make it an ion. Cesium has a lower ionization energy than Lithium, so it is easier to remove electrons, and thus lose electrons, from a Cesium atom than a Lithium atom.
Why is francium more reactive than sodium?
The first ionization energy is lower.

What element has a lower ionization energy than Na?
Potassium
Does Sulfur has a lower ionization energy than chlorine?
no sulfur is practically a gas
Which element has a lower first ionization energy than element S?
Na, sodium
Is it ionization energy is a periodic property?
Ionization energy generally increases across a period as a result of a higher nuclear charge, however there are some exceptions such as Boron which has a lower ionization energy than Beryllium (because it is in a P orbital), and Oxygen which has a lower ionization energy than nitrogen (Because ionization decreases the electron electron repulsion in its orbitals).

Is the ionization energy of alkali metals larger or smaller than the alkaline earth metals in the same period?
It is about first ionization energy. It is less than alkaline earth metals.
Why does Ca have a higher ionization energy than Ga?
because it lower than Ba as you go down ionization energy increases
Which has the higher ionization energy ba or cs?
Ba, because it is lower on the periodic table
