Which statement about subatomic particles is true?
protons are the only subatomic particles to have charge.
electrons are the subatomic particles with the smallest mass.
neutrons orbit the nucleus of the atom.
subatomic particles all have the same mass.

The second option - electrons are the subatomic particles with the smallest mass.

Both protons and electrons have charge (protons are positive and electrons are negative)

Protons and neutrons both equal 1 amu (atomic mass unit), whereas electrons weigh about 1/1000 amu

Electrons orbit around the nucleus, whereas protons and neutrons are inside of the nucleus

And for the last option, I already answered it

Idon’t know sorry i don’t know the answer i’m s sorry
