Ramnik is a student of class 9. One day he was studying a chapter of chemistry in the class alongwith other students. The teacher, Mr. Bhagi, told the students that the scientists James Chadwick J.J. Thomson and E. Goldstein had discovered three subatomic particles P, Q and R, respectively. He gave the characteristics of all these particles, their locations and arrangements in the atom. Mr. Bhagi also described the contributions of scientists Ernest Rutherford and Neils Bohr in this regard. After completing the discussion on this chapter, Mr. Bhagi asked Ramnik to answer the following question : (a) What is the name of particle P ? What is the nature of charge on it ? State its location in tha atom (b) What is the name of particle Q ? What is the nature of charge on it ? State its location in the atom (c) What is the name of particle R ? What is the nature of charge on it ? State its location in the atom (d) (i) Which of the particles P,Q and R is not present in an ordinary hydrogen atom (ii) Which of the particles P,Q and R is not present in an alpha particle ? (e) What is the total number of P and R particles present in one atom of an element known as ? . (f) The number of particles Q in one neutral atom of an element is nineteen. How are these particles arranged in various energy levels in the atoms ? (g) What values are displayed by Ramnik in this episode ?

(a) Describe Thomson's model of the atom. Which subatomic particle was not present in Thomson's model of the atom? (b) The mass number of an element is 18. It contains 7 electrons. What is the number of protons and neutrons in it? What is the atomic number of the element?
