Unit 9: Chemical Bonding, Molecular Shapes, and IMF

Question 1

an atom’s ability to attract electrons from another atom

Answer 1

electronegativity

Question 2

bond between a metal and nonmetal; attraction between cations (+) and anions (-)

Answer 2

ionic bond

Question 3

bond between a nonmetal and nonmetal; sharing electrons to satisfy the octet rule

Answer 3

covalent bond

Question 4

pairs of electrons not involved in bonding

Answer 4

lone pair

Question 5

bond with unequal sharing between 2 different nonmetals

Answer 5

polar bond

Question 6

bond with equal sharing between 2 identical nonmentals

Answer 6

nonpolar bond

Question 7

molecule in which one end is slightly positive and the other end is slightly negative

Answer 7

polar/lopsided molecule

Question 8

molecules that do not have any electrical charges or partial charges

Answer 8

nonpolar/symmetrical molecule

Question 9

dipole

Answer 9

arrows that show areas of higher electron density

Question 10

IMF with formal charges creating a strong bond between ions

Answer 10

ion-ion

Question 11

IMF with a polar molecule that interacts with ions

Answer 11

ion-dipole

Question 12

IMF with attraction between very polar molecules; H with F,O, or N

Answer 12

hydrogen bonding

Question 13

IMF with attraction between less polar molecules

Answer 13

dipole-dipole

Question 14

IMF with weakest caused by “sloshing” around of elections in any atom of molecule

Answer 14

London dispersion

Question 15

Valence Shell Electron Pair Repulsion; says that bonds and lone pairs repel each other

Answer 15

VSEPR

Question 16

electrons involved in a chemical bond; located in the outermost s and p shells

Answer 16

valence electrons

Question 17

2 electrons shared between atoms

Answer 17

single bond

Question 18

4 electrons shared between atoms

Answer 18

double bond

Question 19

6 electrons shared between atoms

Answer 19

triple bond

Question 20

main group elements want either a filled or empty outer s and p sublevels

Answer 20

octet rule

Question 21

polar/lopsided molecules tend to have ______ boiling points because of their charge causes them to want attraction with other molecules and stay in liquid or solid form

Answer 21

higher

Question 22

nonpolar/symmetrical molecules tend to have _______ boiling points because they have little to no charge causing them to not desire attraction and want to stay apart in gaseous form

Answer 22

lower
