Which of these correctly describes a proton?
A proton is the largest subatomic particle of all, has the largest mass, is positive, and is located in the nucleus.
A proton has a mass and size similar to that of a electron, is negative, and is located in the nucleus.
A proton has a mass and size similar to that of a neutron, is negative, and is located in the electron cloud.
A proton has a mass and size similar to that of a neutron, is positive, and is located in the nucleus.
Describe the mass, size, charge, and location of a neutron.
A neutron is positive, has 1 AMU, is large, and located in the nucleus.
