2.3 Study Guide

Question 1

When dealing with Ionic Bonds what happens to the electrons?

Answer 1

atoms transfer electrons

Question 2

When dealing with polar covalent bonds what happens to the electrons?

Answer 2

electrons shared unequally

Question 3

When dealing with nonpolar covalent bonds what happens to the electrons?

Answer 3

electrons shared equally

Question 4

What is a nonpolar bond?

Answer 4

bonding electrons shared equally between two atoms

Question 5

What is a polar bond?

Answer 5

bonding electrons shared equally between two atoms

Question 6

How will electronegativity determine what type of bond two atoms will form?

Answer 6

large difference in electronegativity will result in Ionic Bonds and smaller difference in electronegativity will result in covalent bonds

Question 7

How do Ionic substances dissolve in water?

Answer 7

separate and disperse uniformly

Question 8

How do covalent substances dissolve in water?

Answer 8

dissociate into molecules but not into ions

Question 9

When given two atoms what type of bond will form between them?

Answer 9

covalent

Question 10

When are atoms more stable?

Answer 10

full valence shell

Question 11

How do atoms lose of gain?

Answer 11

attraction for valence electrons

Question 12

Equal electronegativity

Answer 12

equal pull, nonpolar covalent

Question 13

lower electronegativity

Answer 13

weaker pull, polar covalent

Question 14

higher electronegativity

Answer 14

stronger pull, polar covalent

Question 15

Ionic bonding

Answer 15

between atoms with a large difference in EN, opposite sides of the table
