Which compound is covalently bonded

Covalent compounds or molecular compounds are chemical compounds made of elements connected by covalent bonds. Covalent bonds only form between nonmetallic elements because these elements have the same or similar electronegativity values.

Here are examples of covalent compounds and a look at their common properties. You can recognize covalent compounds because they consist only of nonmetals. Alternatively, consult a table of electronegativity values. Helmenstine holds a Ph. She has taught science courses at the high school, college, and graduate levels.

Because it is so unreactive, sulfur hexafluoride is used as a spark suppressant in electrical devices such as transformers. For some simple covalent compounds, we use common names rather than systematic names. We have already encountered these compounds, but we list them here explicitly:.

Methane is the simplest organic compound. Organic compounds are compounds with carbon atoms and are named by a separate nomenclature system that we will introduce in Section 4.

What is the name of the simplest organic compound? What would its name be if it followed the nomenclature for binary covalent compounds? Learning Objectives Identify covalent and ionic compounds.

Determine the chemical formula of a simple covalent compound from its name. Determine the name of a simple covalent compound from its chemical formula. Characteristics of Covalent Molecular Compounds Compounds that contain covalent bonds also called molecular compounds exhibit different physical properties than ionic compounds. Answer b Because sodium is a metal and we recognize the formula for the phosphate ion, we know that this compound is ionic.

Concept Review Exercises How do you recognize a covalent compound? What are the rules for writing the molecular formula of a simple covalent compound? What are the rules for naming a simple covalent compound? Answers A covalent compound is usually composed of two or more nonmetal elements.

It is just like an ionic compound except that the element further down and to the left on the periodic table is listed first and is named with the element name. Name the first element first and then the second element by using the stem of the element name plus the suffix -ide. Use numerical prefixes if there is more than one atom of the first element; always use numerical prefixes for the number of atoms of the second element.

Key Takeaways The chemical formula of a simple covalent compound can be determined from its name. The name of a simple covalent compound can be determined from its chemical formula.
