Question

although all are true, what is the best conclusion from the fact that electrons orbit far away from atomic nuclei?

• electrons are extremely small.
• atoms are comprised mostly of empty space.
• protons have a positive charge.
• atoms consist of subatomic particles.

Explanation:

To determine the best conclusion, we analyze each option:

• "Electrons are extremely small": The fact that electrons orbit far from the nucleus doesn't directly imply their size; it's more about the spatial arrangement within the atom.
• "Atoms are comprised mostly of empty space": If electrons (which are part of the atom) orbit far from the nucleus (where protons and neutrons are concentrated), the region between the nucleus and the electron orbits is largely empty, so this conclusion logically follows from the given fact.
• "Protons have a positive charge": The position of electrons relative to the nucleus has no direct relation to the charge of protons.
• "Atoms consist of subatomic particles": While true, this is a general statement about atoms and not a specific conclusion drawn from electrons orbiting far from the nucleus.

Answer:

B. Atoms are comprised mostly of empty space.
