The maximum capacity of electron accommodation in aluminium is 18 electrons( M shell) on contraty it has only 3 valence electrons whereas boron has maximum capacity of 8 electrons(L shell) and it has 3 valence electrons so electron population of Aluminium is less than that of boron.

The first ionization energy of aluminium is lower than that of boron, because an electron is being removed from a higher energy level.
The first level ionization energy oif aluminium is 577,5 kJ/mol.All alkali metals have lower values for the ionization energy.
As an example potassium has a lower first ionization energy than aluminum (Al).
Lower ionization energy would be associated with the larger atom, as the outer most electrons would be further from the nucleus, and not held as tightly.
The ionization energy is the energy needed to extract an electron from an atom; first ionization energy, second, third etc. can be measured. Reactive chemical elements have lower ionization energy.The first ionization energy for silicon is 786,5 kJ/mol.The first ionization energy for carbon is 1 086,5 kJ/mol.
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. ;)

Because in Boron there is a complete 2s orbital and the increased shielding of the 2s orbital reduces the ionisation energy compared to that seen in Beryllium.
Because fluorine's size is lower than that of iodine, it has a greater ionization energy than iodine. Fluorine, on the other hand, appears to have a smaller shielding effect. As a result, fluorine's nucleus attracts more valence electrons than iodine's.
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).
Barium has more energy levels. So it has lesser ionization energy.
As an example potassium has a lower first ionization energy than aluminum (Al).

The energy required to remove electron from atom are called ionization energy. Larger atom or molecule have lower ionization energy and molecule have higher ionization energy.

no sulfur is practically a gas
