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.

What is the second isotope of hydrogen?
Deuterium, it has 1 neutron and one proton.
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.
What element has one proton and zero neutrons?
Hydrogen ion is the only element that has no neutron and one proton. That is why it is basically a proton.
Can hydrogen have 2 nuetrons?
Hydrogen generally has no neutrons in its nucleus; it consists of just one proton. Isotopes of hydrogen, such as deuterium, have one proton and one neutron, or tritium with one proton and two neutrons.
Does a hydrogen atom have a neutron in its nucleus?
No, a hydrogen atom does not have a neutron in its nucleus. A hydrogen atom consists of only one proton in its nucleus.
What is in hydrogen nucleus?
In a Hydrogen nucleus there is a proton. Hydrogen is the only element to not have a neutron in it's nucleus.
Which particle is not found in hydrogen?
Hydrogen usually has no neutrons. However, there is also the heavy hydrogen, a.k.a. deuterium, that has both a proton and a 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 elements are in deuterium?
Deuterium is an isotope of hydrogen that contains one proton and one neutron in its nucleus. It also has one electron orbiting the nucleus.
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.
What is the second isotope of hydrogen?
Deuterium, it has 1 neutron and one proton.
Which atom do not contain neutron?
Hydrogen-1, (there is a trace of hydrogen-2 (deuterium) found in nature, and hydrogen-3 is an artificial isotope)
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.
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.
The nucleus of deuteron has?
One Proton and one Neutron. It's also called Heavy Hydrogen and has one Electron
Do hydrogen atom consists of a single neutron?
To answer your question: no, hydrogen atoms (the isotope hydrogen-1, protium) consist of a single proton and a single electron.Although they can consist of one proton, one electron and up to six neutrons.
