you cant get the # of neutrons if there is no Atomic Mass because you have to subtract the atomic # from the atomic mass #. so there is no way that u can find the # of neutrons without the atomic mass it is needed!

∙ 15y agoneutrons = mass- number so without them or any other information im pretty sure its not possible.

∙ 16y agoThe number of protons is the same as the number of electrons in an atom. If you have the atomic number then that number is the number of protons and electrons.

If you know the atomic number and the mass number of an isotope how could you figure out the number of neutrons in its nucleus?
The mass number is the total number of protons plus neutrons in the nucleus. The atomic number is the total number of protons in the nucleus. So subtract the atomic number from the mass number and that will give you the total number of neutrons in the nucleus.
What is mass number equal to?
The mass number of an atom is defined as the total number of protons and neutron (collectively called "nucleons") in the atomic nucleus. For example, a helium atom with 2 protons and 2 neutrons would have a mass number of 4.
Is mass number the combining capacity of an element?
No, mass number is the number of neutrons and protons that exist within the nucleus of the atom for a particular element. It is based on the idea that most of the mass of an atom derives from the nucleus.
How is the atomic number and mass number different?
The atomic number is the number of protons in the nucleus of an atom of any given element. The mass number is the number of protons and neutrons in the nucleus of an atom of an isotope of an element.
The mass number represents the number of?
The mass number is the sum of the neutrons and protons which exist in the atomic nucleus of an isotope.
How do you calculate the number of neutrons an element has in its nucleus?
You need to find the atomic number, and the atomic mass. The atomic number i the number of PROTONS in the nucleus, the atomic mass, or mass number, is the number of PROTONS and NEUTRONS in the nucleus. To find the number of neutrons you subtract the atomic number from the mass number.
How do yo find an atoms mass number?
Mass number is the number of protons and neutrons in the nucleus of atom.
How do you find the mass number on an element?
The mass number is the sum of protons and neutrons in the atomic nucleus.
How wold you find a mass number?
The mass number is the sum of neutrons and protons in the atomic nucleus.
Hhow to find the mass number?
The mass number is the sum of protons and neutrons in the atomic nucleus.
Hw do you find the mass number?
The mass number is the sum of protons and neutrons in the atomic nucleus.
How do you find the number of neutrons in the nucleus of uranium?
Number of neutrons in an atomic nucleus = Atomic mass of an isotope - Number of protons in the nucleus For uranium the number of protons is 92; each isotope has of course a different mass.
What does the mass number of an atom help you find?
it helps you find where the nucleus is located
Mass number of nucleus?
The Mass Number is the number of protons plus the number of neutrons in the nucleus.
How do you find the mass number on the periodic table for the elements are calculated?
The mass number is the number of protons plus the number of neutrons in the atomic nucleus.
What number tells the mass of the nucleus of an atom?
The atomic mass number is the mass of the nucleus in atomic mass units.
How do you find the neutrons that are in the nucleus?
Number of neutrons = Atomic mass of an isotope - Number of protons (Atomic number)
