What is the total binding energy and binding energy per nucleon on helium-3 The Answer is BE 7.72MeV and BENUC 2.57MeV. I don't know the steps to get there?
To find the total binding energy Use this formula: B= (number of neutrons)(neutron mass)+ (number of protons)(proton mass) - (Atomic Mass of helium). Then to keep the units correct, multiply that entire expression by 931.5 MeV/u. This is the TOTAL binding energy, and the binding energy per nucleon can be found by dividing the number you calculate above by the total number of protons and neutrons.
Why the mass of hydrogen molecule is greater then the mass of hydrogen atom?
The mass of a hydrogen molecule is greater than that of a single hydrogen atom because a hydrogen molecule consists of two hydrogen atoms bonded together. When two hydrogen atoms bond to form a molecule, they share electrons, resulting in a decrease in the individual mass of each atom. However, the total mass of the molecule is slightly higher due to the binding energy that holds the atoms together.
Which has the greatest number of atoms- 45 grams of Mg 45 grams of F 45 grams of P or 45 grams of Na?
In order to figure out how many atoms are in each sample, you would take 45, multiply it by 6.02 × 1023, and divided by the atomic mass. Since two of the numbers (45 and 6.02 × 1023) will be constants in all of the samples, the number of atoms will differ in each sample due to the atomic mass. 45 × (6.02 × 1023) / atomic mass in grams = number of atoms You could punch out all the numbers to see which sample has the greatest number of atoms, but it is easier to find the atomic mass for all of them and see which one is smaller. A larger atomic mass will mean the equation will be divided by a larger number, meaning the number of atoms will be smaller. So the smallest atomic mass would yield more atoms.Atomic masses:Mg- 24.3 grams***F- 38.0 gramsP- 31.0 gramsNa- 23.0 grams***Note that fluorine is a diatomic moleculeThe sample of 45 g of sodium (Na) would contain the greatest number of atoms

What is the binding energy of a mole nuclei with a mass defect of 0.00084?
The binding energy of a nucleus can be calculated using the mass defect and the relationship E=mc^2, where E is the binding energy, m is the mass defect, and c is the speed of light. With a mass defect of 0.00084 u, the binding energy would be approximately 1.344 x 10^-11 J per nucleus.
What would have the greatest mass 1 mole of iron atoms 2 moles of oxygen atoms 4 moles of carbon atoms or 1 mole of potassium atoms?
1 mole of iron atoms has the greatest mass - 55,845 g.
Why is the relative atomic mass of an element rarley a whole number?
Partly because many elements occur naturally as at least two isotopes, which have different mass numbers, and partly because may isotopes have actual masses that are different from their (always integral) mass numbers. This latter effect is most pronounced among ferrous metal atoms, which have the strongest nuclear binding energies of all atoms and consequently have less actual mass than the sum of the actual masses of all their constituent subatomic particles.
Why is the mass of an atom electrons not included in the atoms mass numbers?
Mass number is defined as the number of protons and neutrons. It is related to Atomic Mass which incudes electron mass and nuclear binding energy , (binding energy reduces the overall mass relative to the combined masses of the protons and neutrons.) Electron mass is not included as mass number is element specific wheras the count of electrons varies depending on the chemical state. The mass of electrons is negligible compared to the mass of the protons and neutrons, binding energy is a larger effect.

Where does majority of a atoms mass come from?
Very nearly all of the mass of an atom is found in the nucleus in the form of Protons and Neutrons. Electrons and "binding energy" contribute a tiny amount of additional mass.

Which subatomic particles account for most of an atoms mass?
The up and down quark accounts for most of an atoms mass. Two up quarks and one down quark forms a proton, and one up quark and two down quarks forms a neutron. Protons and neutrons form the nuclei of atoms, and comprise most of their mass, along with the binding energy holding them all together.
How is nuclear binding energy related to the mass defect?
Nuclear binding energy is the energy required to hold the nucleus together. The mass defect is the difference between the mass of a nucleus and the sum of the masses of its individual protons and neutrons. The mass defect is converted into nuclear binding energy according to Einstein's famous equation, E=mc^2, where E is the energy, m is the mass defect, and c is the speed of light.
How do you work out binding energy?
To calculate binding energy, you subtract the rest mass of the nucleus from the actual mass of the nucleus measured. This difference represents the energy required to disassemble the nucleus into its individual nucleons. The formula is: Binding energy = (Z x proton rest mass) + (N x neutron rest mass) - actual mass of the nucleus.
At what mass number does the binding energy per nucleon peak?
The binding energy per nucleon peaks at a mass number of around 56.
Which element N S Pu or Cl contains the least moles of atoms in a 5.0g sample?
Number of moles = mass / molar mass, so the answer is the one with the greatest molar mass. This is plutonium.
