Molecular Models

QuestionAnswer
Ionic Bond Transfer of electrons so that both have an octet EN greater than or equal to 1.67
Covalent Bond Share electrons so they both have an octet EN less than 1.67
Metallic Bond Dipole, polar, alloys, protons in sea of electrons, good conductors of heat and electricity
Dipole Polar, covalent bond, net pull
Vander Waals Forces Weak, intermolecular, attractive forces
London Dispersion Forces DD (strongest), DN (intermediate), or NN (weakest)
Molecule Two or more atoms
Lewis Structure Number of valence electrons for all atoms in a molecule, organized, complete octets
Sigma Bond End-to-end single, covalent bonds
Pi Bond Covalent, sideways/parallel bonds
Single Bond Covalent, 2 shared electrons (1 sigma)
Double Bond Covalent, 4 shared electrons (1 sigma, 1 pi)
Triple Bond Covalent, 3 shared electron pairs (1 sigma, 2 pi)
Resonance The average of all Lewis structures for a molecule
VSEPR Determines shape and angle from orbital position
Hybridized Orbital The blending of two or more orbitals
Molecular Orbitals New orbitals -> new molecule Bonding and anti-bonding
Bond Order Bond strength (B-A)/2
Paramagnetic 1 or more unpaired electrons Attracted to magnetic field
Diamagnetic No unpaired electrons Not attracted to magnetic field
Coordinate Covalent Bond Shared, come from the same atom
Bonding Orbital Molecular orbital, constructive interference, less energy, more stable
Anti-bonding Orbital Molecular orbital, destructive interference, more energy, less stable *

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.
