How is naming covalent compounds different from naming ionic compounds?

The names of ionic and covalent compounds follow similar principles: They are usually two words. The less electronegative atom is named first. All you have to do is know the formulas and names of the ions.

When naming a covalent compound what is the first element?

Rule 1. The element with the lower group number is written first in the name; the element with the higher group number is written second in the name. Exception: when the compound contains oxygen and a halogen, the name of the halogen is the first word in the name.

What are the rules for naming ionic compounds?

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 metals that can have different oxidation states using roman numerals to indicate positive charge. Example Fe2+ is Iron(II)
  • Name polyatomic ions by their names.

What are the covalent bond prefixes?

Prefixes are used to denote the numbers of atoms present. If the first element exists as a single atom, the prefix mono- is omitted….Binary molecular (covalent) compounds.
