I haven't taken a Science class in almost 20 years so this is new to me.
Please review my work and tell me if/where I went wrong? (In parentensees) is what I am submitting as the answer.
1) The three subatomic particles of the atom include the (protons), (neutrons), and (electrons).
2) The mass of the atom is found almost entirely in the (nucleus).
3) The subatomic particles that orbit the nucleus are the (electrons).
4) Electrons are found in levels called (electronic) (orbitals).
5) The (valanse) electrons are relative particles of the atoms.
6) Chemical bonds are usually formed by the interactions of the electrons of the (outer / outside) energy levels.
7) Two or more atoms held together by chemical bonds form (molecules). Note the (arrangement) of the atoms change.
8) Two types of chemical bonds form most of the molecules in nature. One bond hold atoms together by sharing (covalent bond) and the other hold atoms together by transfering electrons (ionic bond).
9) There are two tpyes of covalent bonds: (non-polar) will share electrons equally while the (polar) will share electrons unequally.
10) When an atom loses electons or gains electrons (atoms becomes electrically charged) an (ion) forms.
11) Because a water molecule has a slightly negative "end" and a slightly positive "end" we refer to it as a (polar) molecule.
12) * was various compounds and their formulas *
13) The most common elements in living matter include: (carbon), (hydrogen), (oxygen), (nitrogen), (calcium).
14) In the universe there are two things: (health - living) and (disease - non living)
15) Energy in the universe flows in the negative subatomic particle called the (electron).
16) List the importances of water and give the importance to living organisms: (Needed six - some of those I have thought of include that "Water is 60% of the human body." Its importance to living things is that "So too is Earth."
17) The (mass, hydrogen) of the water molecules is what gives water its unusual properties.
18) (Hydrogen and Atom) bonds are weak bonds between water molecules. These bonds allow water to keep it molecular integrity when it changes state and also allows it to bond more readily with other substances.
19) An object will usually (dissolve) in water if its density is less than half of water.
20) * was a statement made by the professor *
21) (Hydrodgen ions) are usually ionic, taste sour, and release H ions into water. Their pH is usually low.
22) (pH / Hydrodgen ions, H+) are usually ionic, taste bitter and release OH ions into water. Their pH is usually high.
23) (Salt, Buffers) are substances that help to keep the pH of system within normal limits. (Normal pH of arterial blood 7.3 to 7.45) acid is one such substance in our blood.
