Chemistry Standard 2 Vocabulary

TermDefinition
Chemical Bond An electrical force linking atoms together. Many different ty’pes. ALL involve electrons!
Covalent Bond Bond that results from the sharing of pairs of electrons (two electrons) between NONMETALS (only).
Polarity Describes how equally bonding electrons are shared between atoms.
Hydrogen Bonding Weak attraction between partial (
Molecule Simplest structural unit of an element or compound. Can be one atom, or more than one atom.
Diatomic Molecule made of two atoms. Di-two atomic-atoms. Oxygen, Nitrogen, Chlorine, Fluorine, and Chlorine are diatomic molecules.
Monatomic Molecule made up of only one atom. Noble gasses are key examples of monatomic molecules.
Octet Rule Atoms will lose, gain, or share electrons in order to achieve a full valence shell.
Ionic Bond Bond that results from transfer of electrons (electrical attraction) from metal cations and nonmetal anions. Held together in a repeating pattern (crystal lattice) by electrostatic attraction.
Single Covalent Bond Bond where nonmetals share a pair (2) of electrons.
Double Covalent Bond Bond where nonmetals share two pairs (4) of electrons.
Triple Covalent Bond Bond where nonmetals share three pairs (6) of electrons.
Nonpolar Covalent Bond Bond where electrons are shared equally by bonded atoms.
Polar Covalent Bond Bond where electrons are shared unequally by bonded atoms.
Electrostatic Attraction Force between atoms of opposite charges, holds atoms together in ionic bonds.
0.0 – 0.5 Electronegativity difference in a nonpolar covalent bond.
0.5-1.5 Electronegativity difference in a polar covalent bond.
> 1.5 Electronegativity difference in an ionic bond.
Polyatomic Ions Ions made of more than one atom.
Metallic Bonding Bond resulting from the attraction of metal atoms and the sea of electrons.
Crystal Lattice The unique repeating pattern in the arrangement of atoms in an ionic compound.
Delocalized Electrons Electrons that are not associated with a single atom or one covalent bond.
Salt Ionic compound, produced by electron transfer of nonmetal and metal atom.
Dissociate Ionic compounds dissociate (separate) when dissolved in water.
Electrolyte Solution of ionic compound which conducts electricity.
Intermolecular Force Holds different molecules together. Fights against molecular motion holding molecules in place. Present in solids and liquids, nearly absent in gasses.
Molecular Motion Temperature-dependent movement of molecules. Fights against intermolecular forces.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
