2.3 Chemical Bonding

Question 1

What happens with electrons during ionic, polar covalent, and nonpolar covalent bonds

Answer 1

They transfer with each other.

Question 2

What is a nonpolar bond?

Answer 2

Two Nonmetals
No difference in EN
Shares Electrons EQUALLY

Question 3

What is a polar bond?

Answer 3

Two Nonmetals
Slighter Difference in EN
Shares Electrons UNEQUALLY

Question 4

What is an ionic bond?

Answer 4

One metal and One Nonmetal
Large difference in EN
Does not share electrons.

Question 5

What happens to EN as you go across (left to right) the periodic table? Why?

Answer 5

The pull gets stronger.

Question 6

What happens to EN as you go DOWN the periodic table?

Answer 6

The pull gets weaker.

Question 7

What do chemical bonds provide?

Answer 7

They provide stability.

Question 8

What bond would two hydrogen atoms form?

Answer 8

Non-Polar, the EN is equal so the pull is equal between the two.

Question 9

What bond would two hydrogen and one oxygen form?

Answer 9

Polar, because one has a stronger EN and they are both nonmetals.

Question 10

What bond would a Potassium and Oxygen form?

Answer 10

Ionic, because on is a metal and the other is nonmetal, the difference in EN is also larger.
