Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.

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.
What is the difference of atomic number and atomic mass?
atomic number is the number of protons in the nucleus or electrons around the nucleus in an atom that is not ionized. atomic mass is the sum of the number of protons and the number of neutrons in the nucleus.
What particles make up the atomic mass number of an element?
The atomic mass number of an element is determined by mass of the nucleus of an atom. Therefore the particles that make up the nucleus determine the mass number. These particles are protons and neutrons.The mass of the protons and neutrons do not vary between elements, but the number of each in the nucleus varies between elements and between isotopes of the same element.
What is atomic number or atomic mass?
ATOMIC MASS ;The total numbers of protons and neutrons present in the nucleus of an atom is called atomic mass and it is represented by A ATOMIC NUMBER;the number of protons in the nucleus of an atom are called atomic number or proton number and it is represented by Z
Compare atomic number mass number and atomic mass?
Atomic number is the number of protons in the nucleus of an atom.Mass number is the number of protons plus neutrons in the nucleus of an atom of a specific isotope.Atomic mass is the total mass of a an atom of a particular isotope, not just the mass of the nucleus. Atomic mass is usually measured in atomic mass units (amu), and is the total mass of protons, neutrons, and electrons in an individual atom of the isotope.
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 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.
What is the difference of atomic number and atomic mass?
atomic number is the number of protons in the nucleus or electrons around the nucleus in an atom that is not ionized. atomic mass is the sum of the number of protons and the number of neutrons in the nucleus.
What is the atomic mass of atoms made of?
The Atomic Mass is made up of protons and neutrons (which is basically the nucleus.)
What is the atomic mass of an atom?
The atomic mass of an atom is the combined mass of the protons and neutrons in the nucleus.
What is the sum of protons and nuetons in the nucleus of an atom?
they make up the atomic mass of the element.
What are the differences between the atomic number and the mass number of an atom?
atomic no is the no of protones in a nucleus while atomic mass is the sum of protons and neutrons in nucleus of an atom....
What is the difference between the atomic number and atomic mass of an element?
Atomic number is the number of protons in the nucleus of the atom. But atomic mass is the mass of the nucleus and mass of the electrons around the nucleus. If suppose we say the mass number then it is the total number of protons and neutrons in the nucleus. Nucleon is the common name for both proton and neutron. Hence mass number is the total number of nucleons.
How are the mass numbers and atomic number of a nucleus affected by beta particle?
We make atomic number by number of protons in a atom. We make mass number by total of both protons and neutrons.
What particles make up the atomic mass number of an element?
The atomic mass number of an element is determined by mass of the nucleus of an atom. Therefore the particles that make up the nucleus determine the mass number. These particles are protons and neutrons.The mass of the protons and neutrons do not vary between elements, but the number of each in the nucleus varies between elements and between isotopes of the same element.
What is the mass number of copper?
AMU (Atomic Mass Unit) is the SI masses of particles for nucleus.
