Chapter 6 Vocabulary

Question 1

a mutual electrical attraction between the nuclei and the valence electrons of different atoms that binds the atoms together

Answer 1

chemical bond

Question 2

repulsion be†ween the sets of valence level electrons surrounding an a†om causes these sets to be oriented as far apart as possible

Answer 2

VSEPR theory

Question 3

results in the sharing of electron pairs between two atoms

Answer 3

covalent bond

Question 4

a covalent bond in which the bonding electrons are shared equally by the bonded atoms, resulting in a balanced distribution of electrical charge

Answer 4

non polar covalent bond

Question 5

an uneven distribution of charge

Answer 5

polar

Question 6

bonded atoms have an unequal attraction for the shared electrons

Answer 6

polar covalent bond

Question 7

neutral group of atoms that are held together by covalent bonds

Answer 7

molecule

Question 8

Answer 9

chemical formula

Question 10

shows the types and numbers of atoms combined in a single molecule of a molecular compound

Answer 10

molecular formula

Question 11

the energy required to break a chemical bond

Question 12

uses valence electrons in the form of dots around the element symbol

Answer 12

electron dot notation

Question 13

formulas in which atomic symbols represent nuclei and innershell electrons, dot-pairs or dashes between two atomic symbols represent electron pairs in covalent bonds and dots adjacent to only one atomic symbol represents unshared electrons

Answer 13

Lewis structure

Question 14

a covalent bond in which one pair of electrons is shared between the two atoms

Answer 14

single bond

Question 15

indicates the kind, number, arrangement, and bonds but not the unshared pairs of the atoms in a molecule
