Concept of Atomic Mass

Science > Chemistry > Concept of Atomic Mass and Equivalent Mass > Concept of Atomic Mass The smallest particle of an element which can take part in a chemical reaction is called an atom. According to Dalton’s atomic theory atom is the smallest particle of an element which is indivisible. In modern research, it is proved that […]
