My answer: The 3p electron in aluminum is slightly more distant from the nucleus than the 3s, and partially screened by the 3s2 electrons as well as the inner electrons. Both of these factors offset the effect of the extra proton.
The crystal structure of aluminum is face centered cubic while the crystal structure of magnesium is hexagonal.
Its not the boiling point of aluminum is 2450 and the boiling point of mg is 1120
Chlorine exist as a diatomic molecule and between the molecules there are only weak intermolecular forces, called van der Waals. Magnesium chloride forms an ionic lattice, held by electrostatic attractions between oppositely charged ions. More energy is needed to break the ionic bonds.
Yes aluminum is less reactive than magnesium it is less reactive because as you read left to right on the Periodic Table the elements become less reactive because they get more electrons on their valence shells hope this helps you
I think that it has somthing to do with the fact that Mg doesn't have any electrons in the P sublevel in its outer enery level, but Al has one in the P sublevel in its outer energy level.
Aluminium is much lighter (less dense) than magnesium. That's why they use aluminum on aeroplanes.
The first magnesium ionization energy is 737,7 kJ/mol.
As an example potassium has a lower first ionization energy than aluminum (Al).
Phosphorus. Across the period, first ionization energy increases.
The first level ionization energy oif aluminium is 577,5 kJ/mol.All alkali metals have lower values for the ionization energy.
Sodium has only one valence electron, and when that is donated to some other atom, the remaining ion has a noble gas configuration that is highly stable. Disrupting that by another ionization requires much energy. Magnesium has two valence electrons; therefore the second is almost as easy to donate as the first. The third ionization enthalpy of magnesium would be very high.

The ionization energy of aluminium is 5,985 77 eV. It is a medium energy.
Carbon has the highest ionization energy

Chlorine is Cl, C is carbon. The first ionization energy of magnesium is less than that of chlorine.
Beryllium will have the highest. Down a group ionization energy decreases.
