Atomic Structure

Atomic Structure

1. Fundamental Particles

   • Proton:Mass=1               charge=+1 Neutron:Mass=1                                              charge=0 Electron:Mass=1/1836                                   charge=-1

2. Mass Number and Isotopes

   • Isotopes are atoms which have the same atomic number but different mass numbers. 
   • -Atomic no. = no.of protons  -no.of protons=no. of electrons -mass no. = no. of protons +no. of neutrons

3. Mass spectrometry

4. Electron Configuration

5. Ionisation energy
