Unit 3 Bonding

TermDefinition
Electron configuration The arrangement of electrons in an atom
Covalent bond A bond formed when an atom share one or more pairs of electrons
Ionic bond A force that attracts electrons from one atom to another, which transforms a neutral atom into an ion
Ion An atom, radical, or molecule that has gained or lost one or more electron and has a negative or positive charge.
Lewis dot structure (Electron-dot notation An electron configuration notation in which only the valence electrons of an atom of a particular element are shown, indicated by dots placed around an element's symbol.
Octet rule Ann atom will be more stable when surrounded by 8 electrons in the valence shell (outer most energy level)
Metallic bond A bond formed by attraction between positively charged metal ions and electrons around them
Conductivity Material that is able to conduct electricity
Polar It describes a molecule in which the positive and negative charges are separated.
Non polar A covalent bond in which the bonding electrons are equally attracted to both boned atoms
Bent The central of an atom has two lone pair of electrons, and associated with two bond pairs.
tetrahedral A shape that occurs when there is four bonds and no lone pair in the central atom
trigonal planar It has one atom at the center and three atom on each end forming a triangle.
Linar An element that is bonded to at least two other elements.
Valence electrons An electron that is found in the outermost shell of an atom and that determines the chemical's property
Formula unit The simplest collection of atoms from which an ionic compound formula can be written.
Polyatomic ion a charge group of covalently bonded atoms.
VSEPR Theory It states that repulsion between the set of valence level electrons surrounding an atom causes these sets to be oriented as far apart as possible

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.
