The maximum capacity of electron accommodation of Boron in its outer most shell is eight electrons and that of aluminium is eighteen electrons.
It means that the electron population of aluminium is less than Boron.Due to less electron population the no. Of neighboring atoms in the lattice increase, that's why metallic character of aluminium is less than Boron..
(Correct me if I am Wrong)
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.
Aluminum is less abundant than boron because boron has a higher atomic number and thus is more stable. Aluminium is more reactive and tends to form compounds with other elements rather than existing in its pure form. Boron also has more natural sources and is used in a variety of applications, contributing to its higher population.
The ionization energy of boron is lower than that of beryllium because in boron, the electron being removed is farther from the nucleus, experiencing less of the nuclear charge, making it easier to remove. Additionally, boron's electron configuration involves removing an electron from a higher energy level, which requires less energy compared to removing an electron from a lower energy level in beryllium.
No, BCl3 does not follow the octet rule as boron only has 6 valence electrons in this molecule. Boron can form stable compounds with less than an octet due to its electron deficiency.
Boron (B) would be an electron poor semiconductor when added to silicon because it has one less electron than silicon, leading to an electron deficiency in the crystal lattice.

Yes, it is more metallic. Al has an extra full shell of electrons which shields the positive charge of the nucleus. This means that the outer electrons are held less tightly by the nucleus and therefore lost more easily making it a more metallic element

Sodium is a highly reactive alkali metal whereas aluminium is a less reactive metal in the boron group.
Boron has a lower ionization energy than beryllium because boron has an extra electron in a higher energy level orbital, making it easier to remove. This higher energy level allows the electron to be further from the nucleus, experiencing less attraction, resulting in lower ionization energy.

boron has very small atomic radius.the hypothetical B3+ ion has very small size and hence high charge densities.This value is so high that B3+ ion does not exist.All thecompounds of boron are therefor covalent.Boron has 4 valencce electro n and this gives it a great electron accepting power that is its compound behave as strong lewis acid
The Lewis acid strength of boron trihalides decreases down the group because the size of the halogen atom increases as you move down the group, leading to a weaker attraction between the halogen atom and the electron deficient boron center. Additionally, the ability of the larger halogen atoms to share their electron density with boron decreases, making the boron trihalides less likely to act as Lewis acids.
Boron is sp2 hybridised with an empty p orbital. Both chlorine and iodine have lone electron pairs of suitable symmetry to form a partial pi bond with the empty orbital of boron. This partial pi bond effect is stronger and more significant in BCl3 because there is a better energy match between the empty p of boron (LUMO) and the lone pairs of Cl (HOMO) than between boron p and the lone pairs of iodine. As a Lewis acid, boron takes an electron pair into its empty p orbital. In BCl3, the significant pi bond means that this p orbital is less electron deficient and therefore hinders the ability of the p orbital to accept an electron pair, so it is a weaker acid than BI3. Maybe consult a textbook or website for a picture to help you visualise Boron in sp2 hybridised state.
