The binding arises from the electrostatic attraction of their nuclei for the same electrons. 3. any very small particle. In organic chemistry, there can be more than one chemical compound with the same composition and molecular weight. Nonmetals may combine in a variety of ratios, so it is … A molecular compound is defined as minute pieces of matter connected to each other by neutral particles known as molecules, which share electrons. Let's take a closer look at what that definition means. In the kinetic theory of gases, the term molecule is often used for any … Prefixes and Molecular Compound Names. Compounds consisting of oppositely charged ions are known as ionic compounds, or salts. This process is called dissociation and is the reason that all ionic compounds are strong electrolytes. It is also known as a covalent compound. molecular definition: 1. relating to molecules (= the simplest units of a chemical substance): 2. relating to molecules…. 'Nip it in the butt' or 'Nip it in the bud'? What Is the Definition of a Molecular Compound. A chemical bond formed when electrons are shared between two atoms. Writing covalent compounds involves the use of Greek prefixes. Covalent bonds are much weaker than ionic bonds and, therefore, most of the molecular compounds exist in the gaseous phase. A molecular compound can be defined as a compound where the atoms share electrons through covalent bonds. A molecular compound is represented by its molecular formula formula, in chemistry, an expression showing the chemical composition of a compound. The American Heritage® Student Science Dictionary, Second Edition. Test your knowledge - and maybe learn something along the way. The first element never uses the prefix mono-, but does use all others. What Are the Steps of Presidential Impeachment? Covalent bonds are considered to be a type of chemical bond.
