Q. Illustrate Chemical nomenclature?
Ans.
Chemical nomenclature is the system of names that chemists use to identify compounds precisely. The systematic method of naming compounds is vital to the study of chemistry, because when a new substance is formulated, it must be named in order to distinguish it from all other substances.
Using this systematic method of naming compounds, the positive part is named and written first, followed by the negative part. The names of the elements in the compound are modified with suffixes and prefixes to identify the different types of compounds.
Atoms can combine to form compounds by losing, gaining, or sharing electrons. Chemists have discovered certain trends: it seems that elements tend to form ions with specific charges, and also tend to form only a certain number of covalent bonds. This will be discussed in the following section on oxidation numbers.
