These are the charges on an electron, proton, and neutron.

100
This bond forms when atoms have a more-or-less equal pull on the electrons they share.
What is a (non-polar) covalent bond?
100
This is the name given to a dipole-dipole bond formed between a partially (+) charged hydrogen atom and a partially (-) charged atom, usually oxygen, on another molecule.
What is a hydrogen bond?
100
These are the six elements most commonly found in life.
What are CHONPS?
100
This is a molecule with more than three repeated subunits.
What is a polymer?
200
The reactivity of an atom is determined by the number and placement of these particles in the outer energy level.
What are valence electrons?
200
This bond forms when the difference in electronegativity between two atoms exceeds a value of 1.7 Pauling units.
What is an ionic bond?
200
These forces include dipole-dipole forces and London dispersion forces.
What are van der Waals forces?
200
This formula is the most reduced chemical formula for a molecule class. It would be CH2O for monosaccharides.
What is the empirical formula?
200
This class of molecules is characterized by an almost complete lack of polar functional groups and a non-repetitive structure.
What are lipids?
300
This is a radiation-emitting atom with more or fewer neutrons than average.
What is a radioisotope?
300
In this bond atoms share six electrons in at once bond.
What is a triple bond?
300
This kind of interaction occurs when nonpolar molecules or molecular regions 'flee' from water.
What is a hydrophobic interaction?
300
These are compounds with the same chemical formula that have different structures. For example: glucose and fructose.
What are structural isomers?
300
This level of protein structure is determined by the interactions of amino acid side chains.
What is tertiary structure?
400
This is happens when an electron in an excited state drops back to ground state.
What is the release of a photon / light?
400
This bond is formed when the -OH of a carboxyl group reacts with the -NH2 of an amino group
What is a peptide bond?
400
These are three polar functional groups that are capable of forming non-London intermolecular bonds.
What are....
-NH2, -OH, -SH, -C=O, -COOH?
(any three)
Note: Phosphate is ionic and doesn't count!
400
This kind of reaction adds a molecule of water to break a bond between two monomers.
What is a hydrolysis reaction?
400
These are the two types of secondary structures possible in polymers.
What are alpha (helix) and beta (pleated sheet)?
500
This is the proportion of carbon-14 (half-life 5730 years) that would remain in a sample after 17190 years.
What is one-eighth or 12.5 percent?
500
This type of bond in nucleic acids links adjacent nucleotides between the phosphate group of one molecule and the 3' carbon of the next to form a nucleic acid.
What is a phosphodiester bond?
500
This is the difference in hydrogen ion concentration between pH 3.0 and pH 6.0.
What is 1000 times?
500
In a cyclic molecule, this is the number of the second carbon atom of five if moving in a counter-clockwise direction from an oxygen or nitrogen atom.
What is four prime (4')?
500
This structural carbohydrate is characterized by alpha and beta bonds between saccharide monomers and periodic branchings.
