The mass number of ammonia is 17. This is calculated by adding the number of protons and neutrons in the nucleus, which for ammonia (NH3) is 7 protons and 10 neutrons.
40Ar has 18 protons, 22 neutrons, and 18 electrons.
Iridium-192 has 77 protons and 115 neutrons.
Boron-12 has 5 protons and 7 neutrons.
Cesium has 55 protons, 78 neutrons, and 55 electrons.
The mass number of ammonia is 17. This is calculated by adding the number of protons and neutrons in the nucleus, which for ammonia (NH3) is 7 protons and 10 neutrons.
Neutrons are completely separate from protons, so neutrons do not have any protons, and protons do not have any neutrons.
None -- all protons are protons, which are different from neutrons.
