What is the mass number minus the atomic number called?
Nucleon Number (total number of protons and neutrons)
Atomic mass is an atoms number of what?
it depends because isotopes have different nucleon numbers but their atomic number stays the same.
The number of protons and nuetrons in the nucleus of an atom?
The atomic mass number or nucleon number. The atomic mass number is written in superscript on the left of the elements symbol.
What does the graph of mass per nucleon vs atomic mass number look like?
The graph of binding energy per nucleon versus mass number is an analog of this graph, except it would be upside down. Iron, which has the highest binding energy per nucleon, would have the least mass per nucleon as you looked across the periodic table. Use the link below to see the graph of binding energy per nucleon plotted against mass number. If you "invert" this graph, you'll have yours. If any uncertainty exists as to what is going on with "variable" mass among the nucleons of different elements, use the link below to the related question and investigate why things are the way they are.
What happens to the mass per nucleon in uranium when it is split into smaller nuclei?
The mass of the nucleon is decreased; the difference is released as energy.
What is the mass number minus the atomic number called?
Nucleon Number (total number of protons and neutrons)
Atomic mass is an atoms number of what?
it depends because isotopes have different nucleon numbers but their atomic number stays the same.
What is the atomic mass number of an isotope?
it depends because isotopes have different nucleon numbers but their atomic number stays the same.
When does a nucleon have more mass?
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.
How do you figure out how many neutrons are in a a atom?
Each nucleon (proton or neutron) contributes about 1 atomic mass unit to the mass of the atom. The mass contribution of the electrons can be ignored, since it takes about 1800 of them to equal the mass of a nucleon and the heaviest elements known have around 1/15th that number of electrons. So if you subtract the atomic number (number of protons) from the atomic mass rounded to the nearest whole number (number of nucleons), what's left is the number of neutrons.
The mass number of an atom is the?
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.
How do you determine the number of neutrons for a sodium atom?
Subtract the proton number or atomic number (11) from the nucleon number or the atomic mass (23) and you get the number of neutrons = '''12'''.
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.
