QuestionAnswer
what type of bond forms as a result of orbitals overlapping end to end? sigma
levels of electron in orbits s:2 p:6
theory that states that covalent bonds are formed when orbitals of different atoms overlap is called the VSEPR theory
what bond is the stongest triple bond
how can i know how much sigma and pi bonds are there? always 1 sig and others are pie bonds
the display of an intermediate character within the bonds of such molecules is called resonance
relatively recent theory that predicts the magnetic qualities of diatomic oxygen? molecular orbital theory
the presence of unpaired electrons in molecular orbitals has been associated with what phenomenon? paramagnetism
the theory that states that covalent bonds are formed when orbitals of different atoms overlap is called the valence bond theory
sharing electrons in regions where bonding orbitals overlap is a key characteristics of the valence bond theory
the theory that predicts that there are both bonding and anti bonding orbitals in a molecule is called the molecular orbital theory
repulsion of regions of electron concentration is known as the VSEPR theory
no lone pairs and if two atoms bonding it is always ________ linear
one center atom connected to 3 atoms, no lone pairs trigonal planar
the process by which new kinds of orbitals of equal energy are formed from a combination of orbitals of different energies is known as hybridization
has four electron concentration and one lone pair and three connected, always polar pyramidal
know what is bent one center atom paired to 2 atoms with a lone pair
the symbols delta - delta + represents partial charges of a polar molecule
what determines the polarity of a polar bond? difference in electronegativity
what are always polar ? bent, pyramidal
know how to see dipole moment

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.
