Chemical Bonding

TermDefinition
ionic bond the electrostatic attraction that binds oppositely charged ions together
bent molecular shape molecule with 2 bonding electron pairs and 2 non-bonding electron pairs on the central atom; bond angle of 104.5°
ionic compound a compound composed of positive and negative ions
bond angle angle between bonds in a molecule
intermolecular forces attractive forces that exist between molecules
pyramidal molecular shape molecule with 3 bonding pairs and 1 non-bonding electron pairs on the central atom; bond angle of 107°
bonding electron pairs electrons that are shared between atoms within a molecule
chemical bond attraction that holds atoms together with a compound
linear molecular shape molecular shape with a bond and of 180°.
conductivity ability of a substance to conduct heat/electricity
lone electron pair non-bonding electron pair on an atom
covalent bond a bond formed by the sharing of electrons between atoms
metallic bond the force of attraction between free-floating sea of electrons and positively charged metal ions
tetrahedral molecular shape molecule with 4 bonding pairs and 0 non-bonding electron pairs on the central atom; bond angle of 109.5°
nonbonding electron pair electron pair not involved in a chemical bond
trigonal planar molecular shape molecule with 3 bonding pairs and 0 non-bonding pairs on the central atom; bond angle of 120°
electronegativity the ability of an atom to attract bonding electrons when the atom is in a compound
nonpolar covalent bond a covalent bond in which the electrons are shared equally by the two atoms
valence electrons an electron in the highest occupied energy level of an atom
van der Waals forces the weakest intermolecular attractions—dispersion interactions
sigma bond (σ bond) The strongest type of covalent bond formed from the head-on overlap of orbitals.
pi bond (π bond) Weaker than a 𝜎 bond formed from the sideways overlap of p orbitals.
Hybridization It is the mixing of the atomic orbitals in an atom to produce a set of hybrid orbitals.
Dative (Coordinate) Covalent bond A covalent bond where both electrons in the shared pair are donated by one of the bonding atoms only
Permanent Dipoles A permanent dipole is a permanent difference in the partial charges of covalently bonded atoms.

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.
