Question

Which of the following is the heaviest?
carbon-12
neutron
proton
nitrogen-14

Answer 1

Answer:

nitogen -14 is the heaviest

Answer 2

Nitrogen-14 is the heaviest.

• The mass of nitrogen-14 is 14 amu while the mass of carbon is carbon-14 is 14 amu, all the other options have an even lesser mass.
• Since nitrogen-14 is the heaviest hence option 4 is correct.
• Proton and neutron are the part of a nucleus, proton has a mass of 1 amu while neutron also has a mass of 1 amu hence they cannot be the heaviest.
