Chapter Big Idea. Section 1: Early Ideas About Matter. What are the similarities and differences of the atomic models of Democritus, Aristotle, and Dalton?. The Atom Chapter 11 Section 2 What is an atom made of? Inside the Nucleus Atomic Mass Unit – unit of mass that describes the mass of an atom or molecule. Protons = POSITIVE charge (1 proton = 1amu.) Bell Work. Talk to people around you and write down anything you know about atom. Do not be shy about any idea!. Draw . an atom how you imagine it . (. 1 min. .). Do atoms have mass?. We often say “something has charge”. What does it mean to have charge?. Class: IX Subject: Chemistry Date -01/12/2020 Question 1. What are canal rays? Answer: Canal rays are positively charged radiations which led to the discovery of positively charged sub-atomic part Rutherford proposed that most of the mass of the atom was concentrated. . at the atom’s center. . Rutherford’s Model of the Atom. Rutherford’s experiment suggested that an atom’s positive charge is concentrated in the center of the atom . Do now activity. :. Label the 4 parts of this atom?. What charge is given by the blue particle?. What mass is given to the black particle?. What is the overall charge given to particles in the orange circle?.
