Naming Acids. Simple covalent compounds that contain hydrogen, such as HCl, HBr, and HCN, often dissolve in water to produce acids. These solutions are named by adding the prefix hydro- to the name of the compound and then replacing the suffix -ide with -ic.For example, hydrogen chloride (HCl) dissolves in water to form hydrochloric acid; hydrogen bromide (HBr) forms …

An element is a substance that cannot be chemically decomposed into simpler substances. An atom is the smallest particle of an element that can take part in chemical reactions. A compound is a substance formed from two or more elements chemically joined (bonded) together. A compound has a definite chemical composition and hence specific formula.

Chemical compound - Elements, Molecules, Reactions: Chemical compounds may be classified according to several different criteria. One common method is based on the specific elements present. For example, oxides contain one or more oxygen atoms, hydrides contain one or more hydrogen atoms, and halides contain one or more halogen (Group 17) atoms.

Elements and Compounds. Looking at the left side of the chart, we can see that a pure substance can be either an element or a compound. For example, we mentioned that oxygen is a compound as it consists of two oxygen atoms connected by covalent bonds. Another example can be water where two hydrogen atoms are connected to an oxygen atom.

Compounds Composed of Two Elements. When two nonmetallic elements form a molecular compound, several combination ratios are often possible. For example, carbon and oxygen can form the compounds CO and CO 2.Since these are different substances with different properties, they cannot both have the same name (they cannot both be called carbon oxide).
