aluminum (Al), also spelled aluminium, chemical element, a lightweight silvery white metal of main Group 13 (IIIa, or boron group) of the periodic table.
What group is Aluminium on the periodic table?
Group 3A (or IIIA) of the periodic table includes the metalloid boron (B), as well as the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). Boron forms mostly covalent bonds, while the other elements in Group 3A form mostly ionic bonds.
What is the symbol on a periodic table?
The symbols are abbreviations of the origins of the word for each element. For example, the origin of lead’s symbol, Pb, is the Latin word ‘plumbum’ meaning ‘liquid silver’. The number above the symbol is the atomic mass (or atomic weight).
What is the atomic number for Aluminium?
13
Is aluminum a metal or metalloid?
On the periodic table, the elements colored yellow, which generally border the stair-step line, are considered to be metalloids. Notice that aluminum borders the line, but it is considered to be a metal since all of its properties are like those of metals.
Is aluminium an oxide?
Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula Al 2O 3. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium(III) oxide.
What is se on the periodic table?
selenium (Se), a chemical element in the oxygen group (Group 16 [VIa] of the periodic table), closely allied in chemical and physical properties with the elements sulfur and tellurium. Selenium is a metalloid (an element intermediate in properties between the metals and the nonmetals).
What is FE on the periodic table?

Is aluminum a compound?
Aluminum is a chemical element with symbol Al and atomic number 13.
Is aluminum a metalloid by location?
Aluminium is ordinarily classified as a metal. It is lustrous, malleable and ductile, and has high electrical and thermal conductivity. Like most metals it has a close-packed crystalline structure, and forms a cation in aqueous solution.
Is aluminium an ion?
Aluminium(3+) is an aluminium cation that has a charge of +3. It is an aluminium cation, a monoatomic trication and a monoatomic aluminium.4.3Related Element. Element Name Aluminum Element Symbol Al Atomic Number 13.
Is Aluminium oxide ionic or covalent?
In this lesson, we learned that aluminum oxide is an ionic compound formed between aluminum metal and oxygen. Ionic compounds occur between metals and non-metals and involve the exchange of electrons between the two atoms.
How do you write aluminum oxide?
Aluminum oxide has a chemical formula Al2O3. It is amphoteric in nature, and is used in various chemical, industrial and commercial applications.
What is 33 on the periodic table?
Arsenic, atomic number 33 lies in between phosphorus and antimony in group 15, the so called Nitrogen group of the periodic table.

Why aluminum is a metalloid?
Re: Why aluminum not metalloid? Answer: The physical & chemical properties of aluminum are more similar to the general properties of metals. Since the energy of the valence e- in the d-orbitals are very similar to the transition metals it can have various oxidation states.
Is aluminum or aluminium correct?
The form aluminum is in common use in the United States; the form aluminium is used in Great Britain and by some chemists in the United States.
What is the molar mass of Aluminium?
One mole of Al atoms has a mass in grams that is numerically equivalent to the atomic mass of aluminum. The periodic table shows that the atomic mass (rounded to two decimal points) of Al is 26.98, so 1 mol of Al atoms has a mass of 26.98 g.
How is aluminum made?
Aluminum is manufactured in two phases: the Bayer process of refining the bauxite ore to obtain aluminum oxide, and the Hall-Heroult process of smelting the aluminum oxide to release pure aluminum. of aluminum. In fact, about half a pound (0.2 kg) of carbon is used for every pound (2.2 kg) of aluminum produced.
