Answer:
Question 19: 4. -2
Question 20: 1. -1
Explanation:
Protons always have a positive (+) charge.
Neutrons always are a neutral (0) charge, or no charge.
Electrons always have a negative (-) charge.
<u>Question 19:</u>
We have 8 protons, so a +8 charge.
We also have 10 electrons, so a -10 charge.
-10 + 8 = -2, or a -2 charge.
<u>Question 20:</u>
We have 1 proton, so a +1 charge.
We also have 2 electrons, so a -2 charge.
1 - 2 = -1, or a -1 charge.

Explanation:
Gravity on Uranus is 86% of Earths.
100 pounds x 86% = 86 pounds
You would weigh 86 pounds.
