Get Learning Naming Through Guided Inquiry

A molecular compound is usually composed of two or more nonmetal elements. Molecular compounds are named with the first element first and then the second element by using the stem of the element name plus the suffix -ide. Numerical prefixes are used to specify the number of atoms in a molecule.

And you express those as subscriptsMoreAnd then you take the prefixes that are in front of those names. And you express those as subscripts. So remember that the prefix for one is mono.

How do you name a formula? The first component in the formula is simply identified with the element name. The second component is named by taking the name of the element stem and adding the -ide suffix. The number of atoms in a molecule is determined using a scheme of numerical prefixes.

Binary Covalent Compounds (Type III) The first element shown in the compound is named as the element (e.g., for CO2, first element is "carbon") The second element shown in the compound is named ing to the anion name, ending in -ide (e.g., for CO2, the second element is named "oxide")

Chemical equations and formulas are a vital part of learning chemistry from 11‒19. Being able to use them correctly is part of what it means to be a chemist. Formulas and equations allow chemists to communicate chemical knowledge efficiently.

Rules for Naming Molecular Compounds Write the name for both elements. Change the ending of the second element to ide. Place prefixes in front of each element based on the number of atoms present.

The rule for writing chemical formula is as follow: Firstly, write the symbols with positive charge valency first. Secondly, write the valency of each atom on the top of its symbol. Thirdly, divide the valency number by their highest common factor ignore the positive or negative radicle.

The primary function of chemical nomenclature is to ensure that a spoken or written chemical name leaves no ambiguity concerning to what chemical compound the name refers. Each chemical name should refer to a single substance.

Rules for naming simple ionic compounds. Name the metal by its elemental name. Name the nonmetal by its elemental name and an -ide ending. Name polyatomic ions by their names.
