PERIODIC TRENDS Chapter: Atomic Structure (ELECTRONEGATIVITY(EN) (Factors…

- - - - Has more electrons than the neural atom
      - Increase the repulsion between electrons
      - Atom gains electrons
    - - Increase the effective nuclear charge
      - Attraction between valence electron and the nucleus is stronger
      - Atom loses electrons
  - - - Effective Nuclear Charge (Z eff) increase as :
        -Proton number increase
        -Valence electron have a greater attraction
        -Pulled closer to nucleus
    - - The principle quantum number (n) increase as:
        -Number of shell increase
        -The larger the electron cloud
        -Increase of attraction valence electron to nucleus
