2 - Atomic Structure
Chemistry
Made from Chapter 2 Atomic Structure of Pearson Baccalaureate Chemistry Higher Level, 2nd Edition (Catrin Brown, Mike Ford)
Sample Data
| Front | describe bohr's model of the hydrogen atom [4] |
| Back | pictured as small solar system electron moving in an orbit or energy level around the positively charged nucleus of one proton an electron moves into an orbit or higher energy level further from the nucleus when an atom absorbs energy electrostatic force of attraction between the oppositely charged sub-atomic particles prevents the electron from leaving the atom nuclear radius is 10–15 m and the atomic radius 10–10 m, so most of the volume of the atom is empty space |

| Back | the region around an atomic nucleus in which there is a 90% probability of finding the electron |
