What is the atomic number number of neutrons and the number of electrons of hydrogen?

Normal Hydrogen has an atomic number of 1, no neutrons and 1 electron.


What is hydrogen's number of neutrons equals mass number - atomic number equals?

The number of neutrons in an atom can be calculated by subtracting the atomic number (number of protons) from the mass number. For hydrogen, the atomic number is 1 and the mass number is also 1. Therefore, the number of neutrons in hydrogen is 1 (mass number - atomic number = 1 - 1 = 0 neutrons).


Isotopes of hydrogen differ in what?

Isotopes (of hydrogen) differ in the number of neutrons in the nucleus of the atoms.


What is the number neutrons in a hydrogen ion?

The hydrogen ion H+ has no neutrons.


How many neutrons are in the atom of Hydrogen?

The number of neutrons in a hydrogen atom will depend on which isotope of hydrogen we consider. Not all hydrogen atoms have the same number of neutrons. The vast majority of hydrogen atoms (over 99.98%) have no neutrons at all. Some have 1 (and this is called deuterium) and some have 2 (called tritium). These two isotopes occur naturally but are rare, as can be seen.To determine the number of neutrons in an atom, you must use the mass number, which is the sum of the number of protons and the number of neutrons. Since the atomic number of the element (for H, the atomic number is 1) tells you the number of protons, you can find the number neutrons by subtraction.See the Related Questions to the left for how to count the number of protons, neutrons and electrons in any atom of any element.


If a hydrogen has 2 neutrons is it an isotope?

The number of neutrons in hydrogen depends on the isotope. Protium,deuteriumand tritium have 0, 1 and 2 neutrons respectively.


Do atoms have neutrons in them?

Atoms of all elements can have neutrons in them. Only the element hydrogen has an isotope whose atoms do not contain neutrons, but all other isotopes of hydrogen have neutrons in them. In the heavier elements the number of neutrons always exceeds the number of protons in the atom.


Why are electrons number the same as neutrons number?

They are NOT. The number of electrons and the number of neutrons are not linked at all - for instance, an atom of Hydrogen has one proton and one electron and NO neutrons.


Isotopes of hydrogen have the same what?

Same number of protons, different number of neutrons


What are the atomic number for the hydrogen isotope with 1 neutron?

Atomic number of hydrogen is (always) 1. The mass number is 2, sum of number of protons (1 in H) and neutrons (1 in H in this case). This isotope of hydrogen is called deuterium.By the way: neurons (without t) is a very different thing!


What is the mass number of hydrogen?

The mass number of the most common hydrogen isotope, Hydrogen-1, is one


How does isotopes hydrogen-1 and hydrogen-2 differ?

Isotopes have different number of neutrons, in the given isotopes, there are 0 and 1 neutrons respectively.
