Bonding

Regents Chem Bonding

QuestionAnswer
molecular compound compound with covalent bonds containing nonmetals and/or semi-metals
ionic compound compound with ionic bonds; usually between metals and nonmetals that transferred electrons.
covalent bonds Bond formed when nonmetals and/or semi-metals share electrons
coordinant covalent bonds covalent bonds where the 2 shared electrons come from the same atom. Hydronium (H3O+) and ammonium (NH4+) contain this special type of bond.
polar molecules molecule with an uneven distribution of electrons. Positive and negative regions exist
nonpolar molecules molecule with even distribution of electrons due to its SYMMETRY.
network bonding/network solid strongest intermolecular force. Covalent bonds continue in all directions. Ex. Diamond, graphite and silicon dioxide, silicon carbide
metallic bonding nuclei surrounded by a “sea of moving electrons’ – this is why metals conduct.
intermolecular forces attractive forces between molecules, the stronger they are, the higher the boiling and melting points will be
hydrogen bonding strong attraction between certain polar molecules containing hydrogen bonded to small, highly electronegative elements like N, O and F
molecule ion attractions polar molecules are attracted to ionic compounds. This is how water dissolves salts, by attacking and surrounding the ions
octet rule all elements want 8 valence electrons to become stable. H and He only require 2 electrons (duet rule)
ion a charged element or compound, formed by a gain or loss of electrons
cation The special name for a positive ion; "MEOW"
anion A-Negative ION
formula unit a single piece of an ionic compound
formula represents a compound, using element symbols and their subscripts
electronegativity ability to attract electrons
polar covalent bond unequal sharing of electrons; END is 0.4-2.0
nonpolar covalent bond equal sharing of electrons, usually in diatomic molecules; END 0-0.3
diatomic element 7 elements that cannot exist alone in nature. They bond to themselves (ex: F2)
structural formula Shows bonded and non-bonded e's, element symbols, and the geometry of a molecule
unshared (lone) electron pair Non-bonded electrons. These repel all bonded e's and change symmetry of a molecule.
symmetry A molecule with evenly distributed e's
Has both ionic and covalent bonds Any ionic compound that has a table E ion in it. (the polyatomic ion contains covalent bonds, but the overall bonding is ionic)

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.
