Question

4. A pure coin is made up of billions of silver atoms. The atoms are made
up of subatomic particles including protons, neutrons and electrons. Which of the
following is true about the mass of the coin? (8.5A)
F The mass of the coin comes from the amount of space it takes up divided by the
number of particles.
G Protons and neutrons have much more mass than electrons, and make up most
of the total mass.
H Neutrons have a neutral mass; therefore only protons and electrons contribute
to the total mass.
J The mass is split evenly between the three types of particles.

My answer is A

Answer 1

i think your right.

Answer 2

Two notes.
I see only answers F, G, H, J. I don't see A.
Second, most coins are NOT silver. The "old" dime was 90% silver and 10% copper in the old days but not anymore.
