Chapter 2.  Structure of Atom Some Important Points and Terms of the Chapter 1. The word 'atom' has been derived from the Greek word a-tomio ' which means 'uncutable 'or non-divisible' 2. J.J.Thomson , in 1898 , proposed that an atom possesses a spherical shape (radius approximately  1 0-10 m) in which the positive charge is uniformly distributed. The electrons are embedded into it in   such a manner as to give the most stable electrostatic arrangement (Fig. 2.4, NCERT Page  5) Many different names are given to this model, for example, plum pudding, raisin pudding or  watermelon. 3. Rutherford's Nuclear Model of   Atom : a) Most of the space in the atom is empty as most of the alpha particles passed through the foil undeflected b) A few positively charged alpha particles were deflected. The deflection must be due to enormous  repulsive force showing that the positive charge of the atom is not spread throughout the  atom as Thomson had pres...

 SOME  BASIC CONCEPTS OF CHEMISTRY Join whatsapp group Some Important Points and Terms of the Chapter.... 1. Anything which has mass and occupies space is called matter. 2. Matters exist in three physical states viz. solid, liquid and gas. 3. In solids, these particles are held very close to each other in an orderly fashion and there is not much freedom of movement. In liquids, the particles are close to each other but they can move around. However, in gases, the particles are far apart as compared to those present in solid or liquid states and their movement is easy and fast. 4. Solids have definite volume and definite shape. 5. Liquids have definite volume but not the definite shape. They take the shape of the container in which they are placed. 6. Gases have neither definite volume nor definite shape. They completely occupy the container in which they are placed. 7. A mixture contains two or more substances present in it (in any ratio) which are called its components 8...
