Atomic and ionic radii are found by measuring the distances between atoms and ions in chemical compounds. On the periodic table, atomic radius generally decreases as you move from left to right across a period (due to increasing nuclear charge) and increases as you move down a group (due to the increasing number of electron shells). Similar trends are observed for ionic radius, although ...

The energy released when an electron is added to the neutral atom and a negative ion is formed. Electronegativity (Pauling scale) The tendency of an atom to attract electrons towards itself, expressed on a relative scale. First ionisation energy The minimum energy required to remove an electron from a neutral atom in its ground state.
Aluminum is only about one third as dense as iron, but some of its alloys, such as duraluminum are as strong as mild steel. Duraluminum is formed from 94.3% aluminum, 4% copper, 0.5% manganese, 0.5% magnesium, and 0.7% silicon. While much stronger than pure aluminum, this alloy is less resistant to corrosion and is often clad with pure aluminum.

Hence first ionisation energy of sodium is less than magnesium. When one electron is removed from Na and Mg, their configurations become ls 2 2s 2 2p 6 and 1s 2 2s 2 2p 6 3s 1 respectively. Now it is easier to remove one electron from 3s of Mg+than 2p 6 of Na+. Hence, second ionisation energy of Mg is less than Na.

The first ionization energy of magnesium is larger than sodium because magnesium has one more proton in its nucleus to hold on to the electrons in the 3s orbital. The second ionization energy of aluminum is larger than the first, and the third ionization energy is even larger.
This can be explained by noting that the outermost, or highest energy, electron on a lithium atom is in the 2s orbital. Because the electron in a 2s orbital is already at a higher energy than the electrons in a 1s orbital, it takes less energy to remove this electron from the atom.
An energy level diagram is more useful and easier to work with than quantum numbers in the quantum mechanical model. Chemists use the energy level diagram as well as electron configuration notation to represent which energy level, subshell, and orbital are occupied by electrons in any particular atom.
So by removing an electron, boron actually becomes more favorable, so that's why it's better that it has a lower ionization energy than beryllium. Just remember the common trend of ionization energy is this, but then remember the two exceptions. Group 6A has lower first ionization energy than group 5A if they're in the same period.
The reason why aluminum is becoming specified for so many jobs is its physical properties. For instance, aluminum is three times lighter than steel and yet offers higher strength when alloyed with the right elements. It can conduct electricity six times better than steel and nearly 30 times better than stainless steel.
