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