Which of the following statements about subatomic particles is FALSE? Which of the following statements about subatomic particle

kkurt [141]

Answer:

Protons have about the same mass as electrons is false

Explanation:

Electrons and protons have the same magnitude on charge but opposite sign

$e^{-}=-1.6\times10^{-19}C$ : charge of electron

$e^{+}=1.6\times10^{-19}C$ : charge of proton

Neutrons have no charge.

An atom is composed of protons and neutrons in the nucleus and electrons surrounding it, so a neutral atom has the same number of protons and electrons to has a net charge of zero. So, all the facts mentioned are true.

The false one is that protons have about the same mass as electrons, because the mass of an electron is $9.11\times10^{-31}kg$ and the mass of a proton is $1.67\times10^{-27}kg$ so the mass of a proton is a lot of bigger than electron mass.
