Causes for negative attracting to positive and positive to repel from positive and negative to repel from negative.
Nuclear Force
The nuclear force makes for protons not being able to go with the electrons in its clouds.
The nuclear force is greater because it shows us how it holds back the protons in the nucleus and does not let them reach the electrons in the clouds of the atom.
B. Matter
Define in your own words, give examples, include images and source to reference forbasic chemistry terms needed to understand biochemistry:
atoms: A basic unit with a proton for each electron. When isolated atoms have a neutral charge this means that the protons have a equal number as the electrons.
elements: Made up of the same type of atom.
compounds: Two or more elements chemically bonded together.
molecules:Two or more atoms chemically bonded together.
ions: An atom that is charged due to a differing number of protons and electrons.
radioactivity: Energy released by a atom when the nucleus is not stable do to not enough nuclear force to hold back the protons.
isotopes: Atoms of the same element with the same number of protons but a different number of neutrons.
E. Chemical Bonds
Covalent Bonds are formed when valence electronss in atomic orbits are shared.
Examples of Covalently Bonded Molecules:
Water
DNA
Chlorine, right
Ionic Bonds are formed when valence electrons in atomic orbits are transfered.
Examples of Ionically Bonded Molecules:
Sodium Chloride
Sodium Bromide
Calcium CHoride
Metallic Bonds are formed between metal atoms when valence electrons form a "metallic ele___n sea". Examples:
Iron
Steel
Brass
Hydrogen Bonds are electromagnetic attractive interaction between polar molecules in which hydrogen is bound to a highly eletronegative atom.
Van der Walls Forces are the sum of the attractive or repulsive forces between molecules
Bond types (in order of decreasing strength):

C. The Atom
This is a helium atom it has two electrons, two protons, and two neutrons Source: http://0.tqn.com/d/chemistry/1/7/w/2/1/helium-atom.jpg
The Quantum Mechanical Model of the atom is the current theory of the atom that states that.... (summarize briefly in your own words).
D. Sub-Atomic Particles
Protons: The number of portons in an atom say what element it is. If the number of protons is changed a new element is formed
Electrons:The number of electrons in an atom say what charge the element has. If an electron is taken away then a isotope is formed
Neutrons: The neutrons determine whether the nucleus is stable or not if the number of neutrons in an atom is altered then a isotope is formed.
F. Water and It's Importance to Life
Include the following in your discussion about water:
Water's Molecular Structure Discuss polartiy, adhesion and cohesion properties.
Water in Solutions and Suspensions Discuss water as the universal solvent and define solute and solvent.
Acids, Bases and pH What causes something to be acidic, basic, what is the pH scale and how is water involved in acidity.
