A brief description of the relationships among each of the following groups of terms or phrases is to be written Atom, molecule, formula unit Concept introduction: The principles of chemistry deal with the study of substances and the energy related with their change. Usually, the mass associated with everything is referred as matter. Moreover, matter can be viewed as macroscopic and microscopic samples. The view point of matter at particulate level is tiny to observe, models are generally used to represent particles. In common, chemists use models of atom and molecules to represent tiny particles based on experimental data. Commonly, the chemical compounds are made up of polyatomic ions and the ratio of positive to negative ions present in the substance is expressed as formula of ionic compound.

ings ools Molecular compounds are usually composed solely of nonmetals. A binary molecular compound is one in which the compound contains only two elements (regardless of how many atoms are present of each). When naming binary molecular compounds, prefixes are used to specify the number of atoms of each element. Take a moment to review some of the prefixes shown here. Prefix Number mono di nona one three tetra four penta five hexa six hepta seven octa eight nine deca two ten For example, SF6 is named sulfur hexafluoride. Note that the prefix mono is not used in naming the first element. Also note that the second element in the name should end with the suffix ide. ▼ Part A Using the rules for naming molecular compounds described in the introduction, what is the name for the compound PC15?
