" The subject seemed to us very attractive and all the more so because the question was entirely new and nothing yet had been written upon it."- Marie Curie 1.All matter is made of atoms. Atoms are indivisible and indestructible. 2.All atoms of a given element are identical in mass and properties 3.Compounds are formed by a combination of two or more different kinds of atoms.

 * Marie said that radiation came from inside the atoms.
 * Scientist followed her lead and discovered the structure of atoms.
 * Marie and her husband discovered two new atoms radiation and polonium.
 * In chemistry and physics, **atomic theory** is a theory of the nature of matter, which states that matter is composed of discrete units called atoms, as opposed to the obsolete notion that matter could be divided into any arbitrarily small quantity.
 * All the atoms in an element aren’t the same. Elements have isotopes which have the same //properties. // But they don’t have the same atomic mass or number. Atoms can also be destroyed, only by nuclear reactions.
