How Do I Use's Assign Lesson Feature? study So, 'mono-oxide' would become monoxide. Naming the first element - Simply write the element and add a prefix if there's more than one element. Hydrogen is an exception to this rule in that hydrogen only needs two electrons to have a full valence shell. Log in or sign up to add this lesson to a Custom Course. What are the rules for naming covalent compounds? The element that has the lower group number is listed first. Does the compound name give you any clues about the formula? Earn Transferable Credit & Get your Degree, Ionic Compounds: Formation, Lattice Energy and Properties, Factors Influencing the Formation of Ionic Bonds, What is a Metallic Bond? Sciences, Culinary Arts and Personal This rule is often ignored because diatomic covalent compounds made of one type of element are so common: dihydrogen (H2 ) is just called hydrogen; dichlorine (Cl2 ) is just called chlorine.

Nikki has a master's degree in teaching chemistry and has taught high school chemistry, biology and astronomy. Uneven sharing results in the formation of what is called a dipole, or the separation of charges between two covalently bonded atoms. 'Co' means share and 'valent' refers to valence electrons. Before we get started naming, let's look at some simple covalent compound names and their formulas at the same time. ), The Secret Science of Solving Crossword Puzzles, Racist Phrases to Remove From Your Mental Lexicon. All rights reserved. An atom is made of a positive nucleus and the negatively charged electrons that surround it. Also, you probably noticed that there are prefixes attached to some of the element names. Methane, or natural gas, is a covalent compound made of one carbon bonded to four hydrogens via single bonds. Each letter in this device represents an element that deviates from our standard naming rule because it naturally occurs bonded to an atom of the same element. Before we begin, take a couple breaths. Select a subject to preview related courses: You might recognize many of these prefixes from common things! Is the Coronavirus Crisis Increasing America's Drug Overdoses? What are the physical properties of covalent compounds? Valence electrons are the outermost electrons of an atom. The shared valence electrons between two nonmetal atoms is called a covalent bond. Think about the term covalent. Naming the second element - The second element will always begin with a prefix and end with 'ide.'

Covalent bonds are formed when two atoms begin sharing electrons. Let's follow the naming rules and name some compounds: N2 O:N, nitrogen, is in group 15, and O, oxygen, is in group 16, so the nitrogen gets listed first. Covalent compounds also are known as molecular compounds. Four shared electrons are known as a double bond and six shared electrons are known as a triple bond.
