STRUCTURE ON THIS ATOM In Chapter 3, we have learnt that atoms and From these activities, can we conclude molecules are the fundamental building that on rubbing two objects together, they blocks of matter. The existence of different become electrically charged? Where does this kinds of matter is due to different atoms charge come from? This question can be constituting them. Now the questions arise: answered by knowing that an atom is divisible (i) What makes the atom of one element and consists of charged particles. different from the atom of another element? (ii) Are atoms really indivisible, as scientists contributed in revealing proposed by Dalton, or are there smaller the presence of charged particles in an atom. constituents inside the atom? We shall find It was known by 1900 that the atom was out the answers to these questions in this indivisible particle but contained at least one chapter. We will learn about sub-atomic sub-atomic particle-the electron identified by particles and the various models that have J.J. Thomson. Even before the electron was been proposed to explain how these particles identified, . Goldstein in 1886 discovered the are arranged within the atom. are arranged within the atom. A major challenge before the scientists at and called them canal rays. These rays were the end of the 19th century was to reveal the positively charged radiations which ultimately structure of the atom as well as to explain its led to the discovery of another sub-atomic important properties. The elucidation of the particle. This sub-atomic particle had a charge, structure of atoms is based on a series of equal in magnitude but opposite in sign to that One of the first indications that atoms are of the electron. Its mass was approximately not indivisible, comes from studying static 2000 times as that of the electron. It was given electricity and the condition under which the name of proton. In general, an electron is electricity is conducted by different represented as 'e and a proton as " . The 4.1 Charged Particles in Matter considered to be negligible and its charge is For understanding the nature of charged minus one. particles in matter, let us carry out the protons and electrons, mutually balancing following activities: their charges. It also appeared that the protons Activity 4.1 were in the interior of the atom. for whereas A. Comb dry hair. Does the comb then not protons. Now the big question was: attract small pieces of paper? not protons. Now the big question was: B. Rub a glass rod with a silk cloth and what sort of structure did these particles of bring the rod near an inflated balloon. the atom form? We will find the answer to Observe what happens. this question below.
