Atoms And Molecules

Subatomic Particles
1. Electrons
  1. Negitive Charge
2. Neutrons
  1. Neutral Charge(No Charge)
3. Protons
  1. Postive Charge
Ionic and Covalent Bonds
1. Ionic Bond
  1. Attraction Between Anions and Cations(lone valence electron is transfered to a different atom)
    1. Anions
      1. Net negative Charge
    2. Cations
      1. Net Positive Charge
    3. Example: An uncharged Sodium atom pairs up and gives a valence electron to a charged Chloride Atom to create NaCl
2. Covalent Bond
  1. Sharing of Valence Electrons
    1. Single Bond: Sharing of one pair of valence electrons
    2. Double Bond: Sharing of two pairs of Valence electrons
Molecules
1. Molecule: Combination of 1 or more atoms to form a bond
  1. H + H=H2
2. Compound: Combination of more than 1 element
  1. Ex: Sodium plus Chloride=NaCl
Ions
1. an atom or molecule with a net electric charge ready to gain or lose one or more valence electrons
Anabolism and Catabolism
1. Anabolism: a process which requires energy and produces complex molecules from simpler ones
2. Catabolism is the breaking down of things - a series of degradative chemical reactions that break down complex molecules into smaller units, and in most cases releasing energy in the process.
