Section 9.1- Types of Chemical Bonds

Question 1

is composed of two or more elements that have combined chemically

Answer 1

compound

Question 2

is an attractive force between atoms that is strong enough to enable the group to act as a unit

Answer 2

chemical bond

Question 3

simple ionic compounds and molecular compounds typically have very __________________ properties

Answer 3

different

Question 4

the most important factor affecting how atoms form chemical bonds is the

Answer 4

number of valence electrons in each atom involved

Question 5

the principle that states that the atoms will tend to react chemically so as to achieve a noble-gas electron configuration, either by losing or gaining electrons or by sharing electrons with other atoms, therefore obtaining additional stability

Answer 5

octet rule

Question 6

ionic bonding is literally the

Answer 6

“transfer” of electrons

Question 7

as a rule, elements toward the ______________ of the periodic table tend to lose electrons in bonding, while elements toward the __________ of the periodic table tend to gain electrons in bonding

Answer 7

left- lose
right- gain

Question 8

atoms that gain electron become

Answer 8

anions

Question 9

atoms that lose electrons become

Answer 9

cations

Question 10

a chemical bond in which positively charged ions are electrically attracted to negatively charged ions is an

Answer 10

ionic bond

Question 11

ionic compounds do not consist of

Answer 11

molecules

Question 12

the elements on the left side of the periodic table (metals) react with elements on the _____________________________ to form ionic crystalline solids

Answer 12

far right side (nonmetals)

Question 13

a chemical bond that results from the SHARING of valence electrons between atoms is a

one atom is bonded to the other because both are attracted to the electrons shared between them

Answer 13

covalent bonds

Question 14

________________________ of both positive nuclei for the negatively charged electron cloud holds the nuclei together in a covalent bond

Answer 14

mutual attraction

Question 16

when two atoms share a single pair of electrons the bond is a

Answer 16

single covalent bond (single bond)

Question 17

two or three pairs of electrons shared by two atoms form a

Answer 17

multiple bond

sharing two pairs of electrons forms a

Answer 18

double bond

sharing three pairs of electrons

Answer 19

triple bond

some compounds, especially those containing _________________, include both ionic and covalent bonds

Answer 20

polyatomic ions

Question 21

pairs not involved in a bond

Answer 21

lone pairs or nonbinding pairs
