Question

choose all that are correct.
a proton...
...a negligible mass.
...is located in the empty space surrounding the nucleus.
...has a charge of 1+.
...has no charge.
...has a charge of 1-.
...is located in the nucleus.
...has a mass of 1 amu.
...has a mass of 1 gram.

Explanation:

• A proton has a charge of 1+ (protons are positively charged particles).
• A proton is located in the nucleus (protons and neutrons make up the atomic nucleus).
• A proton has a mass of 1 amu (atomic mass unit; protons and neutrons each have a mass of approximately 1 amu).
• A proton does not have negligible mass (its mass is significant in atomic structure, ~1 amu).
• Protons are not in the empty space around the nucleus (that's where electrons are).
• Protons are not neutral (neutrons are neutral) or negatively charged (electrons are negative).
• A proton's mass is not 1 gram (1 amu is much smaller than 1 gram).

Answer:

-...has a charge of 1+.
-...is located in the nucleus.
-...has a mass of 1 amu.
