If you add the number of protons and neutrons in an atomic nucleus, you get the number of nucleons. This is usually a good approximation to the Atomic Mass in amu, since both protons and neutrons have a mass that's pretty close to one amu. The number will be slightly off, because electrons contribute as well, protons and neutrons don't have exactly the same mass, and there's something called the atomic mass defect that has to do with the binding energy of the nucleus, but it should be fairly close.

When the number of protons and neutrons is added the result will be its atomic mass or mass number.

∙ 16y agoThe number of protons and neutrons combined is the atomic mass. The electrons are not included in this equation because they have very little mass.

What elements is hydrigen made of?
Hydrogen contains one proton and one neutron in it's nucleus with one electron orbiting around the nucleus.
What form of hydrogen has 1 proton and one neutron in its nucleus?
Regular hydrogen.
Which element have no neutrons in its atom?
The most common isotope of Hydrogen lacks a neutron in its nucleus. But there is an isotope, called deuterium, that has one neutron. Additionally, there is a hydrogen isotope that is artificially created that has two neutrons in its nucleus. It is called tritium. A link to the Wikipedia article on the isotopes of hydrogen is provided.
Are hydrogen-3 and helium-3 isotopes of the same element?
No. hydrogen-3 (tritium) has a nucleus with one proton and two neutrons, and is unstable. Helium-3 has a nucleus with two protons and one neutron, and is stable.
How many protons does an atom of the first element listed on the periodic table have?
Hydrogen, being the first element, has one proton and one neutron in its nucleus.
What is found in the nucleus of all elements except for hydrogen?
A neutron, although this is not always the case as there are hydrogen atoms with neutrons, but hydrogen atoms are the only one which are able to not have a neutron.
What is an example of an atom without a neutron?
The only element that does not have a neutron in its nucleus is hydrogen-1, which consists of one proton and one electron.
How do the isotopes hydrogen 1 and hydrogen 2 differ?
The basic difference is a neutron. Most hydrogen has a single proton for a nucleus. Hydrogen-2 has a neutron stuck to the proton, and hydrogen-3 has two neutrons stuck to the proton. Hydrogen-3 is a rare and highly unstable form of the first element.
What elements is hydrigen made of?
Hydrogen contains one proton and one neutron in it's nucleus with one electron orbiting around the nucleus.
How many protons are in the H nucleus?
Hydrogen has just one proton. If the nucleus also has a neutron, the isotope is called Deuterium.
What form of hydrogen has 1 proton and one neutron in its nucleus?
Regular hydrogen.
The nucleus of deuteron has?
One Proton and one Neutron. It's also called Heavy Hydrogen and has one Electron
Which element have no neutrons in its atom?

Additionally, there is a hydrogen isotope that is artificially created that has two neutrons in its nucleus. It is called tritium. A link to the Wikipedia article on the isotopes of hydrogen is provided.
Difference between deuterium and tritium?
Deuterium is an isotope of hydrogen that has 1 neutron (an ordinary hydrogen atom has none). A nucleus of tritium has 2 neutrons.
Are hydrogen-3 and helium-3 isotopes of the same element?
No. hydrogen-3 (tritium) has a nucleus with one proton and two neutrons, and is unstable. Helium-3 has a nucleus with two protons and one neutron, and is stable.
How is hydrogen in heavy water different from hydrogen in normal water?
Type your answer here... The hydrogen atoms in heavy water have a neutron in the nucleus, doubling the mass.
Where are neutron electron protons located?
Neutons, located in the nucleus. Protons, also located the the nucleus but Elecrons, there is further study.
