MnBr₃ would be called manganese(III) bromide as the charge is different.Īlthough it doesn't seem like much, these rules can sometimes be confusing. For example, MnBr₂ is manganese(II) bromide - Mn has a charge of 2+. This is done by writing the Roman numeral in parentheses following the element name. Some cations, usually transition metals, can take on multiple charges and we want to specify which ion we are considering. Generally, these refer to the oxidation number of an atom, but it's a bit different for ionic compounds.
IONIC EQUATION CALCULATOR HOW TO
The chemical name definition is obvious, but knowing how to name chemical compounds in practice can be tricky, especially if we combine polyatomic ions. If you're interested in finding out how chemical bonds are related to the stability of ions, check the bond order calculator. The chemical name calculator can assist you in naming ionic compounds. If you've ever heard of alkenes, they fall under this category. Hydrocarbons - A type of covalent compound, these are the simplest kind of organic compounds as they're composed of only hydrogen and carbon. As they tend to exist as individual molecules and not huge ionic lattices of repeating units, it's necessary to state the amount of each element when naming them. An example would be sodium bicarbonate, NaHCO 3.Ĭovalent compounds - In this group, as we've mentioned, we have only non-metals as only they are capable of forming covalent bonds. Acid salts are ionic compounds containing acidic hydrogen, but not necessarily as the only counterion.For instance, HCl, a common chemical compound, can be called both hydrogen chloride and hydrochloric acid. Although they can be termed the same way as the ionic compounds, they're usually given special names. Ionic compounds - They are also obtained by combining metals, but this time instead of non-metals, we have polyatomic ions such as cyanide, CN⁻.Īcids - They are the compounds in which the cation is H +. It's not to be confused with a diatomic compound, which has multiple atoms of the same element. There may also be more than one of each element in the compound. There are various types of compounds, such as:īinary ionic compounds - As the name suggests, these are formed from two different elements, a metal and a non-metal. a pollution of 1 gram of benzene in a certain amount of water converts to N A/78.11≈ 7.Hold on, how are you meant to know what is a binary ionic compound if we haven't told you what is a compound itself? In chemistry, this term describes a substance composed of identical molecules consisting of atoms of two or more elements. Using the above calculator you could find that e.g. Or 1 mole of a substance will contain Avogadro's number of that substance. The term " mole" is defined in that one mole of a substance with a molecular (or atomic) mass of one (1), will have a mass of 1 gram. It is defined to be 1/12 of the mass of one atom of carbon-12 and in older works is also abbreviated as "amu".Īlso, important in this field is Avogadro's number (N A) or Avogadro's constant (6.0221 x 10 23).
In related terms, another unit of mass often used is Dalton (Da) or unified atomic mass unit (u) when describing atomic masses and molecular masses. Molecular mass or molar mass are used in stoichiometry calculations in chemistry. This Calculator has been tested on Internet Explorer version 6 only,įirefox might not show all fields correctly.
