The number of neutrons in an atom is not a constant. It is equal to or greater than the number of protons, and the number of neutrons changes the Atomic Mass number, as the proton number is constant. Atoms with different numbers of neutrons are called isotopes. Some are stable, some are unstable, some are radioactive.

∙ 10y agoPlease note that atoms of a single element may have different amounts of neutrons. In other words, the element may have different isotopes.
To look up this information, you can search the Wikipedia for the element that interests you, then select the "Isotopes of [element]" section.

An atom with 55 protons and 76 neutrons?
An atom with 55 protons is a cesium atom. The mass number is the sum of the numbers of protons and neutrons, in this instance 131. Therefore, the atom is Cs-131.
Where about in an atom would you find a proton?
You can find a proton in the nucleus of the atom along with neutrons.
How many netrons are in a nitrogen atom?
In a nitrogen-14 atom, there are 7 neutrons, where the isotopes with mass numbers with 13 and 15, have 6 and 8 neutrons respectively.
An atom of an element has 54 protons some of the elements atoms have 77 neutrons while other atoms have 79 neutrons what are the atomic numbers and mass numbers of the two types of atoms of this el?
12343 neutrons
Isotopes exist because atoms of the same element can have a different numbers of what?
Isotopes are different atoms of the same element with the same number of protons (proton number) but different in number of neutrons. Given that nucleon number is equal to the sum of proton and neutrons in the nucleus of an atom, isotopes have different nucleon number due to difference in number of neutrons.
Atom does not have to have equal numbers of protons and?
An atom does not have to have equal numbers of protons and neutrons.
How many neutrons would you expect to find in a helium atom?
There are several isotopes of Helium and they have different numbers of neutrons. The simplest and most common is Helium-4 which has two neutrons
What is an atom that has varing numbers of neutrons?
A single atom that has varying numbers of neutrons is undergoing a nuclear reaction. However, the questioner probably meant, "What is the name for different atoms of the same element that have differing numbers of neutrons?", and the answer to that question is "isotopes"
Where in an atom do you find a neutrons?
you can find the neutron in the center of an atom.
What part of an atom do you find neutrons?
in nucleus of atom
How much neutrons and protons and electrons in a atom?
These numbers actually vary between atom to atom.
What is the atomic mass of a atom?
The sum of the numbers of protons and neutrons.
How do you find the neutrons for an atom?
Neutrons = Mass number - Number of Protons
An atom with 55 protons and 76 neutrons?
An atom with 55 protons is a cesium atom. The mass number is the sum of the numbers of protons and neutrons, in this instance 131. Therefore, the atom is Cs-131.
Where about in an atom would you find a proton?
You can find a proton in the nucleus of the atom along with neutrons.
Where would you find a neutron in a atom?
The neutrons of an atom are located in the nucleus (except hydrogen-1 isotope which has no neutrons).
Where in a atom would you find a neutron?
