![]() The other fluoride of tin is SnF 4, which was previously called stannic fluoride but is now named tin(IV) fluoride.Ĭhemists use nomenclature rules to clearly name compounds. Chlorine element (Cl) is in group 17 and period 3 of a periodic table. The name is derived from the Greek chloros, meaning greenish yellow. This represents the formula SnF 2, which is more properly named tin(II) fluoride. Negative ions that consist of a single atom are named by adding the suffix -ide to the stem of the name of the element. Element Chlorine (Cl), Group 17, Atomic Number 17, p-block, Mass 35.45. It has 16 isotopes with mass numbers ranging from 31 to 46 of which only Cl-35 and Cl-37 have a natural existence with a stable half-life 3. Denoted by the chemical symbol Cl, it categorized as a nonmetal 1, 2. Melting Point: -100.98 C (172.17 K, -149.764 F) Boiling Point: -34.6 C (238.55 K, -30.279997 F) Number of Protons/Electrons: 17. For example, you may see the words stannous fluoride on a tube of toothpaste. Chlorine (pronounced as KLOHR-een) is a highly reactive diatomic gas belonging to the family of halogens. Though this naming convention has been largely abandoned by the scientific community, it remains in use by some segments of industry. We could write the chemical formula for this ionic compound as MgClCl MgClCl, but the convention is to use a numerical subscript when there is more than one ion of a given type MgCl2 MgCl 2. Out-of-date nomenclature used the suffixes – ic and – ous to designate metals with higher and lower charges, respectively: Iron(III) chloride, FeCl 3, was previously called ferric chloride, and iron(II) chloride, FeCl 2, was known as ferrous chloride. Now the positive and negative charges are balanced. \): Names of Some Transition Metal Ionic Compounds Transition Metal Ionic Compound Holmium, Ho, periodic table element with name, symbol, atomic number and weight.
