(a) Interpretation: The formulas of compounds in which the combining ratios are as follows: Potassium: Oxygen, 2: 1. Concept Introduction: The substance having similar atom is called an element. When two or more elements combined together chemically they form a pure substance called a compound. But in case of mixture, it is formed when two substances joined together without any chemical bonding. Example of compound is H 2 O, and example of element is N, example of mixture is mixture of sand and sugar. The symbols of chemical elements are abbreviated that are used to denote the chemical element. Most of the chemical symbols correspond directly to the name of the element in English, although few are derived from the Latin or German.
