A molecule that is made up of 2 atoms of either the same or different elements

Question 20

What does monatomic mean?

Answer 20

A single atom.

Question 21

If Sodium has 1 electron on it’s outer shell will it need to lose or gain an electron to get a full outer shell?

Answer 21

Lose 1 electron to gain a full outer shell.

Question 22

If Flourine has 7 electrons on it’s outer shell will it need to lose or gain an electron to get a full outer shell?

Answer 22

Gain 1 electron to gain a full outer shell because 8 electrons means a full outer shell.

Question 23

What are the noble gases?

Answer 23

Hellium, Neon, Argon

Question 24

Why are noble gases unreactive?

Answer 24

They all have full outer shells so they can't lose or gain
