Yes, that is correct. A proton and neutron each have a mass of approximately 1 Atomic Mass unit (amu). This unit is commonly used to express the mass of subatomic particles in relation to the standard carbon-12 atom.
Atomic mass is the total mass of protons, neutrons and electrons in a single atom.
Protons and neutrons each have a mass approximately equal to one atomic mass unit.
Both the proton and the neutron have a mass of approximately one atomic mass unit (amu). The proton has a mass of 1.00728 amu and the neutron has a mass of 1.00867 amu.
1 proton and 1 neutron is needed because the 2 in hydrogen 2 refers to the atomic mass and protons and neutron have a mass of about 2 daltons each.
No, the designations of hydrogen for the proton and neutron for the neutron do not imply that these two particles are of equal mass. A proton is about 1836 times heavier than a neutron. The terms "hydrogen" and "neutron" were historically used to describe these particles based on their properties and roles in atomic structure, rather than their masses.
The approximate atomic mass of a neutron is 1 unified atomic mass unit, which is equivalent to 1.008665 atomic mass units when considering the mass excess.
