What is aluminums period on the periodic table?
Aluminum is the 13th element on the periodic table. It is located in period 3 and group 13. Aluminum is element number 13 with the element symbol Al. Under ordinary pressures and temperatures, it is a light shiny silver solid metal. Helmenstine, Anne Marie, Ph.D. "Aluminum on the Periodic Table."
What period and group is zinc in?
hexagonal close-packed (hcp) Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a silvery-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table.
What family number is aluminum in?
The aluminum family consists of elements in Group 13 of the periodic table: boron (B), aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). The family is usually named after the second element, aluminum, rather than the first, boron, because boron is less typical of the family members than is aluminum.
What is the mass number of aluminum?
Mass numbers of typical isotopes of Aluminium are 27.
What is the first ionization energy of aluminum?
First Ionization Energy of Aluminium is 5.9858 eV.
What is the electronegativity of aluminium?
The electronegativity of Aluminium is: χ = 1.61
What is the most abundant element in the Earth's crust?
Aluminium is a silvery-white, soft, nonmagnetic, ductile metal in the boron group. By mass, aluminium makes up about 8% of the Earth’s crust; it is the third most abundant element after oxygen and silicon and the most abundant metal in the crust, though it is less common in the mantle below.

When was aluminum discovered?
Aluminium, or Aluminum in American spelling, is an ancient metal and has a diverse range of uses. It was discovered in 1824 and its light weight, high electrical conductivity and high resistant to corrosion has make it an industrially attractive metal.
Where is aluminium found?
It primarily exists in form of ores and the most common ore of Aluminium is bauxite. The largest producers of Aluminium in the world are China, Russia, Bahrain, and South Africa.
What is aluminium foil used for?
Aluminium foils are widely used all over the world. Aluminium is used in the manufacturing of cars, trucks, bicycles and marine vessels. Aluminium is widely used construction and building material, such as doors, building wire, windows and roofing.
How many isotopes of aluminum are there?
Isotopes of Aluminium. Aluminium has only one stable isotope, Aluminium-27. Among the radioactive isotopes, the most stable is Aluminium-26 and have a half life of about 720,000 years.
What are the characteristics of aluminium?
Chemical Characteristics. Aluminium is a reactive metal. It is readily oxidized when exposed to air. The most common oxidation state of Aluminium is +3. Aluminium reacts with oxygen and sulfur to form oxides and sulfates, which have various industrial applications. It readily reacts with acids and bases.
When was manganese discovered?
Manganese is an ancient metal and was discovered as a distinct element in 1774. It…. Magnesium. Magnesium is an ancient element and is characterized as an alkaline earth metal. it was….
Does aluminum affect soil fertility?
Inhalation of powdered welding fumes of Aluminium can lead to fibrosis of the lungs [4]. In environment, Aluminium can affect the soil fertility as it reacts with phosphate and makes it less available for the plants [5].
Where did aluminum come from?
Aluminium was discovered by Hans Christian Oersted in 1825 at Denmark. Origin of name: from the Latin word " alumen " meaning " alum ".
What is pure aluminum?
Pure aluminium is a silvery-white metal with many desirable characteristics. It is light, nontoxic (as the metal), nonmagnetic and nonsparking. It is somewhat decorative. It is easily formed, machined, and cast. Pure aluminium is soft and lacks strength, but alloys with small amounts of copper, magnesium, silicon, manganese, and other elements have very useful properties. Aluminium is an abundant element in the earth's crust, but it is not found free in nature. The Bayer process is used to refine aluminium from bauxite, an aluminium ore.
How is aluminium mined?
Aluminium is mined in huge scales as bauxite (typically Al 2 O 3 .2H 2 O). Bauxite contains Fe 2 O 3, SiO 2, and other impurities. In order to isolate pure aluminium, these impurities must be removed from the bauxite. This is done by the Bayer process. This involves treatment with sodium hydroxide (NaOH) solution, which results in a solution of sodium aluminate and sodium silicate. The iron remains behind as a solid. When CO 2 is blown through the resulting solution, the sodium silicate stays in solution while the aluminium is precipitated out as aluminium hydroxide. The hydroxide can be filtered off, washed, and heated to form pure alumina, Al 2 O 3.
How is pure aluminium obtained?
The next stage is formation of pure aluminium. This is obtained from the pure Al 2 O 3 by an electrolytic method. Electrolysis is necessary as aluminium is so electropositive. It seems these days that electrolysis of the hot oxide in a carbon lined steel cell acting as the cathode with carbon anodes is most common.
What is the solution of sodium aluminate and sodium silicate?
This involves treatment with sodium hydroxide (NaOH) solution, which results in a solution of sodium aluminate and sodium silicate. The iron remains behind as a solid. When CO 2 is blown through the resulting solution, the sodium silicate stays in solution while the aluminium is precipitated out as aluminium hydroxide.
How many electrons does aluminium have?
Aluminium atoms have 13 electrons and the shell structure is 2.8.3. The ground state electronic configuration of neutral aluminium is [ Ne ]. 3s2. 3p1 and the term symbol of aluminium is 2P1/2. Your user agent does not support the HTML5 Audio element. Pure aluminium is a silvery-white metal with many desirable characteristics.
Is aluminium a toxic substance?
Aluminium may be involved in the action of enzymes such a succinic dehydrogenase and δ-aminolevulinate dehydrase (involved in porphyrin synthesis. Aluminium compounds are toxic to most plants and somewhat toxic to mammals. Aluminium has been linked to Alzheimer's disease (senile dementia). More biological data...
