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

The electronic configuration shows that electron population of Aluminium is less than that of boron.Due to less electron population,the number of neighbouring atoms in the lattice increases,so Al is more metallic

Yes! Aluminum is more metallic then boron due to less electron population, number of neighbouring atom in the lattice increases, so Al is more metallic.

Why is the metallic bond in aluminum stronger than metallic bond in sodium?
because the atoms are larger and cannot be held together as strongly by the mobile electrons.
Why does aluminum have a higher melting point than Sodium?
Metallic bonding is between metal ions in a sea of delocalised electrons. In Aluminum, there are more delocalised electrons and the ions have a higher charge than Sodium. There is a greater force of attraction between the electrons of aluminum because the protons that are pulling on a 3+ ion are stronger than a 1+ ion. Since it requires more force to overcome these forces of attraction, Aluminum has the higher melting point. - Troy Moss
Is aluminum more electronegative than sodium?
Aluminum is more electronegative than sodium. The electronegativity of aluminum is 1.61. The electronegativity of sodium is 0.93.
Does boron have more density than water?
Boron density: 2,08 g/cm3 Water density: 1 g/cm3
Lithium is more active than aluminum?
Apex - trueYes, lithium is more active (reactive) than aluminum.
Is borax metallic or non metallic?
Borax is a mineral that is a compound of the element boron. It is not a metal. Boron is a metalloid, rather than a metal.
What elements would you expect exhibit properties most similar to those of aluminum?
The elements immediately above and below aluminum in the same column of a wide form periodic table: boron and gallium. As is usual for relatively light elements, aluminum is more like the element below it, gallium, than the one above it: Aluminum and gallium are both metals, while boron is a nonmetal. In compounds with oxyanions, however, boron is similar to aluminum compounds with oxyanions.
What is aluminum louvers?
a LOUVER is something that keeps rain out and lets air in. Aluminum is a metallic material different than wood.
Which periodic table contain more metallic elements than nonmetallic elements?
metallic elements are found in the center of the periodic table, and nonmetallic elements are anywhere but the middle...
Why is the metallic bond in aluminum stronger than metallic bond in sodium?
because the atoms are larger and cannot be held together as strongly by the mobile electrons.
What has two more protons than boron?
Boron has 5 protons and Nitrogen has 7.
Does Al have a larger atomic radius than B?
Aluminum has a larger radius than Boron because there are more electron filled 'orbitals' around its nucleus. Atomic radius increases down a group for that reason.
Is bismuth more metallic or less metallic than nitrogen?
Bismuth is more metallic than nitrogen; nitrogen is a gas, nonmetal and bismuth is a posttransition metal.
Is chlorine more dense than boron?
At room temperature chlorine is a gas, boron is a solid. So at room temperature boron is much denser than chlorine.
Is metallic luster more common than non-metallic luster?
no

If Aluminium is more abundant than iron so why wasn't it used until the beginning of the twelfth century?
The greater abundance of aluminum is based on its presence in compounds. Obtaining metallic aluminum from its abundant compounds requires a higher concentration of energy than obtaining iron from its compounds.
