You subtract the atomic number from the atomic weight. For example, if you have a helium atom and its atomic weight is 4 and you subtract its atomic number (2) the number of neutrons in the helium atom is 2.

How can you figure the numbers of neutrons in an atom?
You subtract the atomic number from the atomic weight. For example, if you have a helium atom and its atomic weight is 4 and you subtract its atomic number (2) the number of neutrons in the helium atom is 2.
How do you figure out how many neutrons are found in an atom?
Finding out how many neutrons are in a atom is easy. All you have to do is find the element's atomic number and atomic weight.
How many neutrons are in one atom?
The number of neutrons depends on the atom. In general, mass number = atomic number + number of neutrons.
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom can affect the atomic mass of an atom.
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.
What does the number of neutrons determine?
they determine the atomic mass of the atom
The number of neutrons plus protons in the nucleus of an atom-?
nass number is the number of neutrons plus protons in the nucleus of an atom
What is the name of the number neutrons of an atom?
Of course, number of neutrons or neutron number !
How do you find the neutrons for an atom?
Neutrons = Mass number - Number of Protons
What is the number of an atom with 5 protons and 7 neutrons?
To the find the mass number of an atom you add the protons and neutrons. Meaning that the mass number of this atom is 12.
How many neutrons are there in an element having a mass number of 155 and an atomic number of 63?
The number of neutrons in the nucleus of an atom is always the difference between the mass number of the atom and the atomic number of the atom. Therefore, in this instance, there are (155 - 63) or 92 neutrons in the atom.
Why can an atom have the same number of neutrons and still be an isotope?
an isotope is defined by an atom with the same number of protons, but a different number of neutrons
