Short Notes On Atomic Structure * Atom is the smallest particle of an element- All 117 elements has atoms * Bohr model: - Planetary model (see Figure 1 below) 1. Sun (proton & neutron= nucleus) 2. Planets (electrons) 3. Orbit (shell) Figure 1: Bohr model * Each type of atoms has a certain number of electrons and protons that differentiate it from the atoms of other elements Example: 1 proton 1 electron= Hydrogen (1 type elements) 2

CHEM 101 – General Chemistry I Chapter 2 Reading Assignment Pages 31 - 60 2.1 – What is Matter Made Of? Who 1st discovered atoms – Democritus where the first person to discover atoms. His followers would often think that there were multiple kinds of atoms and not just plain atoms. 2.2 – How Do We Classify Matter? Elements – A substance that consists of identical atoms. Today there are 116 known elements. Example – C= Carbon; H= Hydrogen Compounds – A pure substance made up of two or more elements
