Historically the dining room is furnished with a rather large dining table and a number of dining chairs; the most common shape is generally rectangular with two armed end chairs and an even number of un-armed side chairs along the long sides.
Protons and neutrons do not have the same mass. Their masses are quite close, but they are noticeably different. For some purposes it is okay to equate the neutron and proton mass, but it's just an approximation.Also, neutrons decay into a proton, an electron and an antineutrino.rotons and neutrons do not have the same mass.

Do protons weigh the same as neutrons? YES AND NO When using Relative Atomic Mass (Mr), a proton weighs the same as a neutron. This is rounded to the nearest whole number, however. The actual weight of â¦ a proton is 1.0073 amu. The actual weight of a neutron is 1.0087 amu. As you can see the neutron actually has slightly more mass (weight) than a proton has. When using figures to calculate Mr, however, as in most periodic tables, the mass of protons and neutrons is both 1.
