1 amu = 1 nucleon
An even number really has no meaning
Mass number in chemistry is the number of nucleons in the nucleus. Nucleon is the common name for proton and neutron. In case of Sodium atom the mass number is 23. If it gets changed by adding one more neutron then it is an isotope which is used in medical field as a radio isotope to study about the blood flow.
you can divide a number which make it
what does the number 27 mean?
The nucleon number is not 35.5! Chlorine has isotopes with 35 or 37 nucleons but a fractional number is not possible.
add the number of nucleus and proton number
Nucleon Number (total number of protons and neutrons)
In chemistry and physics, a nucleon is one of the two particles that make up the atomic nucleus. Protons are one of the nucleons, Neutrons are the other nucleon.Thus by subtracting the number of Protons in the nucleus (the Proton number) from the total number of nucleons (the nucleon number) you will get the total number of Neutrons (the neutron number) in the atoms nucleus.
The nucleon number (or mass number).
The mass number also refers to the nucleon number. Usually the larger number among the two present in the periodic table, the nucleon number refers to the number of protons and neutrons present within an atomic nucleus of an element.
isotopes
i think it's 7 cause 14 -7=7
A nucleon has more mass when it is not bound to the nucleus of an atom. When the nucleon is bound to other nucleons the binding energy that keeps them together comes from the mass of the nucleon. Therefore the mass of a single nucleon will be smaller in an atom than on it's own.
No need to add. Use the elemnts mass number, which is the number of protons plus the number of neutrons
it depends because isotopes have different nucleon numbers but their atomic number stays the same.
