1.2 - Water

Question 1

How can stability in electron configurations be achieved?

Answer 1

Through some degree of electron sharing

Question 2

What bond is formed when electrons are shared pretty equally?

Answer 2

Covalent bond

Question 3

What bond is formed when electrons are shared pretty unequally? Explain what each atom of the pair does?

Answer 3

Ionic bond. One atom gives up an electron (becoming positive) to the other atom (becoming negative)

Question 4

What is a polar covalent bond?

Answer 4

It’s when two regions within a molecule are oppositely and slightly charged; thus creating a dipole within the molecule

Question 5

What is an example of a molecule with a polar covalent bond? What is it’s negative and positive regions?

Answer 5

Water. Oxygen accepts electrons becoming the negative region. Hydrogen gives away electrons becoming the positive region

Question 6

What effect does this dipole in water have?

Answer 6

1. Water is attracted to one another creating a weak bond called a hydrogen bond

Question 7

How many hydrogen bonds can each water molecule make?

Answer 7

4

Question 8

What is a solution?

Answer 8

A mixture of one or more solutes
