Which statement compares the masses of two subatomic particles?
(1) The mass of an electron is greater than the mass of a proton.
(2) The mass of an electron is greater than the mass of a neutron.
(3) The mass of a proton is greater than the mass of an electron.
(4) The mass of a proton is greater than the mass of a neutron.

Sagot :

IwAsSoMeGuYidn
Electrons have mass 0
Protons have mass 1
Neutrons have mass 1

(1) 0 is not greater than 1
(2) 0 is not greater than 1
(3) 1 is greater than 0
(4) 1 is not greater than 1

So the answer is (3) The mass of a proton is greater than the mass of an electron

atoms are made of 3 types of subatomic particles - electrons, protons and neutrons

mass of proton is 1 atomic mass unit and proton is also 1 atomic mass unit

masses of protons and neutrons are very similar

mass of an electron is 1/1840th of 1 atomic mass unit

mass of electron is insignificant when compared to masses of neutrons and protons

protons and neutrons have a larger mass than electrons

from the given options correct answer is

(3) The mass of a proton is greater than the mass of an electron
