Molecular compounds Although they may not be ionic compounds, chemically bonded compounds of two different elements can be thought of as being made up of an element with a more positive chemical nature, and one that has a more negative nature in comparison. Elements on the left hand side of the periodic table prefer to donate electrons (thus taking on a more positive chemical nature), and elements on the right hand side prefer to accept electrons (thus taking on a more negative chemical nature ). The element with the more positive nature in a compound is named first . The second element is named with an -ide ending . Often a pair of elements can form several different molecular compounds. For

Unformatted text preview: example, Carbon and Oxygen can form CO and CO 2 . Prefixes are used to identify the relative number of atoms in such compounds: • CO carbon mon oxide (carbon mono oxide) • CO 2 carbon di oxide Such prefixes can extend for quite a way for some organic and polymeric compounds (a common detergent in shampoos is sodium dodecylsulfate, or "SDS", also known as Sodium Laurel Sulfate because it sounds more benign and holistic). The list of such prefixes includes: Prefix Meaning Mono-1 Di-2 Tri-3 Tetra-4 Penta-5 Hexa-6 Hepta-7 Octa-8 Nona-9 Deca-10 Undeca-11 Dodeca-12...
