Let’s learn about INDIUM!

    Indium is a chemical element with the symbol In and atomic number 49. Indium is the softest metal that is not an alkali metal. It is a silvery-white metal that resembles tin in appearance. It is a post-transition metal that makes up 0.21 parts per million of the Earth’s crust. Indium has a […]

Let’s learn about ZIRCONIUM!

  Zirconium is a chemical element with the symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon; zar-gun, “gold-like” or “as gold”)), the most important source of zirconium.It is a lustrous, grey-white, strong transition metal that closely resembles […]

Let’s learn about POTASSIUM!

    Potassium is a chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force.[5] Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It […]

Let’s learn about ALUMINIUM!

    Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the […]

Let’s learn about LITHIUM!

    Lithium (from Greek: λίθος, romanized: lithos, lit. ‘stone’) is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element. Like all alkali metals, lithium is highly reactive and flammable, and must be […]

Let’s learn about SODIUM!

    Sodium is a chemical element with the symbol Na (from Latin “natrium”) and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23Na. The free metal does not happen in nature, and must […]

Let’s learn about CHLORINE!

    Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly halfway between them. Chlorine is a yellow-green gas at room temperature. It is a very reactive element and a strong […]

Let’s learn about NITROGEN!

    Nitrogen is the chemical element with the symbol N and atomic number 7. It was first discovered and (separated far from others) by Scottish doctor Daniel Rutherford in 1772. Although Carl Wilhelm Scheele and Henry Cavendish had independently done so at about the same time, Rutherford is generally given/gave the credit because his […]

Let’s learn about CARBON!

    Carbon (from Latin: carbo “coal”) is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent–making four electrons available to form covalent chemical (forces that glue or join things together). It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of […]

Let’s learn about HELIUM!

        Helium (from Greek: a¼¥Î»Î¹Î¿Ï‚, romanized: Helios, lit. ‘Sun’) is a chemical element with the symbol He and atomic number 2. It is a clear/white, odorless, (having no taste/rude and offensive), non-poisonous, not moving/powerless, monatomic gas, the first in the noble gas group in the periodic table. Its boiling point is the […]
