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.

User: Describe the particles that make up the nucleus of an atom in terms of mass and charge. Weegy: Protons, neutrons and electrons. Protons have a relative mass of 1 and a charge of +1, they are found in the nucleus of an atom. Neutrons have a relative mass of 1 and no charge, [ they are also found in the nucleus. Electrons have a relative mass of 1/1836 and a charge of -1.
