Concept explainers
a)
Interpretation:Name and molecular formula of compound formed from
Concept introduction:In the molecular formula, the exact number and type of constituent atoms are shown. Type of constituent atoms is represented by their atomic symbols and the number of each constituent atom is represented by right subscript of its atomic symbol. The number of each constituent in a molecule depends on its valency. The valency of an element is calculated from its electronic configuration, that is how many electrons it can lose or gain to attain a stable electronic configuration.
