. For instance, hydrogen is combustible and oxygen is a supporter of combustion. But their product, water, neither burns, nor helps in burning. It actually extinguishes fire. Another familiar example is that of sodium and chlorine. Sodium is a violently reactive metal while chlorine is a highly poi..

. Metalloids are the elements, which have properties that lie between those of metals and non-metals, e.g., arsenic, antimony, etc. Molecules of elements may consist of single atom, two atoms, or even more. All the hundreds of thousands of compounds existing, and produ..

Summary - Pure substances are made up of only one type of constituent particles. They are homogenous and have a definite set of properties characteristic of themselves. An element is a pure substance that is made up of only one kind of atoms. An atom is the smallest particle of an el..
