  2. Atomicstructure H e 4 Atomic mass number of neutrons = The sum of protons and neutrons in an atom 2 Atomic number Number of Protons in an atom number of protons number of electrons = - - - Atomic mass Atomic mass Atomic mass Atomic number electron proton

  3. Electronic Configuration Electrons are arranged in Energy Levels or Shells around the nucleus of an atom. the arrangement of the electron in the atom. l x n no.of electrons Sub energy level Main energy level f f = 7 x 2 = 14 d d p 1 4 3 2 p d = 5 x 2 = 10 p s s s nucleus s p = 3 x 2 = 6 s = 1 x 2 = 2 32e- 2e- 8e- Atomic orbital 18e- 1 Atomic orbital = 2 e-
