The Hydrogen's and Oxygen's of water molecules are attracted, because H is partially (+) and O is partially (-).
What is hydrogen bonding?
100
2 or more atoms covalently bonded.
What is a molecule?
100
The amount of heat required to raise a substance's temperature 1 degree Celsius.
What is heat capacity?
100
Electrons occupy orbitals singly before they pair.
What is Hund's Rule?
100
The most stable elements with a full valence shell of 8 electrons.
What are the noble gases?
200
Water maximizes its # of H bonds by forming a curved surface.
What is surface tension?
200
The smallest unit of matter made of protons, electrons, & neutrons.
What is an atom?
200
Equal to the number of protons.
What is the atomic number?
200
Electrons in the highest energy level of an atom.
What are valence electrons?
200
One unit of an element is equal to the atomic weight in grams of that element.
What is a mole?
300
Water bonding with surfaces.
What is adhesion?
300
An atom/ion is most stable with a full valence shell of 8 electrons.
What is the octet rule?
300
The sharing of electrons betweens nonmetals that produces molecules.
What is covalent bonding?
300
Electrons shared evenly across covalent bonds.
What is a nonpolar molecule?
300
A pure substance made up of only one type of atom.
What is an element?
400
The amount of solutes dissolved in water alters its properties (freezing point, boiling point).
What are colligative properties?
400
Atoms covalently bonded with at least 2 different elements.
What is a compound?
400
Equal to the number of neutrons & protons together.
What is atomic mass?
400
Electron attraction power.
What is electronegativity?
400
An element with a changed # of neutrons, and therefore a changed mass.

What is Avagadro's number?
500
The transferring of electrons between metal and nonmetal that produces salts.
What is ionic bonding?
500
Electrons shared unevenly across covalent bonds resulting in partial charges at poles of molecule.
What is a polar molecule?
500
