Ch 6 Section 1

Question 1

A chemical bond is a mutual electrical attraction between the

Answer 1

Nuclei of valence electrons of different atoms that binds the atoms together

Question 2

Most atoms are at relatively high

Answer 2

Potential energy

Question 3

Nature favors arrangements in which potential energy is

Answer 3

Minimized

Question 4

Most atoms are less stable existing by

Answer 4

Themselves than when they are combined

Question 5

By bonding with each other atoms decrease in

Answer 5

Potential energy creating more stable arrangements of matter

Question 6

When atoms bind their valence electrons are

Answer 6

Redistributed in ways that make the atoms more stable

Question 7

The way electrons are redistributed determined the

Answer 7

Type of bonding

Question 8

Main group metals tend to lose electrons to

Answer 8

Form positive ions

Question 9

Nonmetals tend to gain electrons to form

Answer 9

Negative ions

Question 10

Ionic bonding: chemical bonding that results from the

Answer 10

Electrical attraction between cations and anions

Question 11

In purely ionic bonding atoms completely

Answer 11

Give up electrons to other atoms

Question 12

Atoms joined by covalent bonding

Answer 12

Share electrons

Question 13

Covalent bonding results from the

Answer 13

Sharing of electron pairs between two atoms

Question 14

In a purely covalent bond the shared electrons are

Answer 14

Owned equally by the two bonded atoms

Question 15

The degree to which bonding between atoms of two elements is ionic or covalent can be estimated by calculating the

Answer 15

Difference in the elements’ electronegativities

Question 16

Between 0 to 0.3 in electronegativity difference: the hind is

Answer 16

Nonpolar covalent

Question 17

Between 0.3 and 1.7 in electronegativity difference: vine is

Answer 17

Polar covalent.

Question 18

Between 1.7 and 3.3 in electronegativity difference: bond is

Answer 18

Ionic

Question 19

Bonding between two atoms of the same element is

Answer 19

Completely covalent

Question 20

Nonpolar covalent bond: a covalent bond in which the bonding electrons are shared

Answer 20

Equally by bonded atoms, resulting in a balanced distribution of electrical charge

Question 21

In bonds with significantly different electronegativities the electrons are more strongly

Answer 21

Attracted by the more electronegative atom

Question 22

Polar bonds have an

Answer 22

Uneven distribution of charge

Question 23

A polar covalent bond: a covalent bond in wh in the bonded atoms have an

Answer 23

Unequal attention for the shared electrons

Question 24

Atoms seldom exist as

Answer 24

Independent particles in nature
