Chemical Bonds:Stability in Bonding

Chapter 20

Section 1


Compounds

Compounds

  • Combination of Elements

  • Properties different than the individual elements

    Ex: Sodium Chloride(NaCl) Table Salt

    Na – highly reactive

    Cl – Poisonous Gas

    NaCl - Stable


Formulas

Formulas

  • Chemical Formula

    • The elements a compound contains and the exact number of atoms of each element

  • Examples:

    Sand – Silicon Dioxide – SiO2

    Cane Sugar – Sucrose – C12H22O11


Valence electrons

Valence Electrons


Atomic stability

Atomic Stability

  • Stable when the outer energy level is complete

  • Noble Gases

    • 8 valence electrons


Chemical bonds stability in bonding

  • Atoms with partially stable outer energy levels can gain, lose, or share electrons


Ionic bond

Ionic Bond

  • NaCl


Covalent bond

H2O

Covalent Bond
