The binding energy is the mass defect, times the square of the speed of light.The amount stated seems to be an awfully high mass defect, though.

The energy and particles given off during a nuclear reaction are called?
Radiation
How does mass relate to binding energy in the nucleus?
The mass defect represents the mass converted to binding energy
How has basic knowledge about atomic nuclei been used in technology?
Knowledge about atomic nuclei has been used to produce energy.
Compare and contrast fusion and fission?
With nuclear fission, a large atomic nucleus (such as a uranium nucleus) breaks apart into smaller nuclei, and energy is released. With nuclear fusion, small atomic nuclei (such as hydrogen) join to become larger nuclei, and energy is released. Fusion of hydrogen releases much more energy than any other type of either fusion or fission. Note that the dividing line between heavy nuclei and light nuclei is the iron nucleus, which is at the perfect point of nuclear stability, so that neither fusion nor fission of iron nuclei would release any energy.
Energy produced when atoms split or when atoms join to form one atom?
This is just called nuclear energy (or Atomic energy).Yes a beautiful phenomenon!When lighter nuclei combine together heat energy is evolved along with some radiations. This is known as nuclear fusion. Very good example is the sun and stars where energy is produced only by this phenomenonWhen a heavier nuclei split into lighter ones, once again heat is produced along with some kind of radiations. This is known as nuclear fission. Good example is the nuclear reactor where lot of heat energy is produced which in turn gets used to produce electricity.The secret in nature goes this way. The simplest atom is the hydrogen where we have the lowest number ie one proton and one electron in its surrounding orbits.According to Einstein, mass has come out of energy. So let us assume this hydrogen as one energy ball. When such four energy balls get combined together, certain amount of energy is given out in the form heat and other radiations and new ball named helium is formed.There by, the mass of the product produced, namely helium, will be found less than the expected mass of the constituents ie two protons and two neutrons in the nucleus of the helium.This is termed as Mass Defect. We use a convenient unit of mass in this situation instead the SI unit, kilogram. That convenient unit is atomic mass unit. Simply amu.Same way eV is a convenient unit for energy instead joule.In physics, the equivalent energy to this mass defect is named as binding energy (BE). It means that the energy already come out during binding process. Binding energy of a nucleus is divided by the number of nucleons in the nucleus. This is said to be binding energy per nucleon (BE/A), an important detail which would explain the secret of emission of heat energy during fission process.Let us note the salient point that higher the BE/A more energy would be given out while forming such nuclei.As we plot the BE/A with A in a graph, BE/A is found to be maximum (8.8MeV) for iron (A=56). So iron is the most stable element. (We call those, who is very stubborn, as a person with iron heart) This BE/A is found to be very low (2 M eV) for hydrogen, helium etc. (A slightly more than1). Same way it is comparatively lower (7.7MeV) for higher nuclei such as uranium, thorium etc. (A = round about 230 and above)Thus when hydrogen get fused to form helium its BE/A increases.When such uranium nuclei get split, it gives out some elements with lower A (barium, krypton). So elements with higher BE/A is formed. In turn, we easily understand that more energy would be given out. So, when heavier nuclei get split, enormous energy is liberated. This is how nature with its intelligence plays this dramatic behaviour.The same intelligence, inherent in human, finds out this secret and has started to use that nuclear power positively in generating electricity. Unfortunately, misused by the same human brain, in the form of atom bomb exploded at Hiroshima. The problem is, along with heat energy some radiations such as alpha, beta and gamma rays are produced which are harmful.The most advantage in nuclear fusion is that it gives harmless radiation but the pity is to start such nuclear fusion enormous energy is needed. That is "starting trouble".If we find a good technique to keep fusion going on in a convenient way, then power crisis would come to an end, once for all.
What is the binding energy of a mole of nuclei with a mass defect of 0.00084 kg?
7.56 x 10^13 J/mol
Is the binding energy the same for all nuclei?
No. Binding energy differs from element to element,
the mass defect for the nucleus of helium is 0.0303 amu what is the binding energy per nucleon for helium in MeV?
For helium the binding energy per nucleon is 28.3/4 = 7.1 MeV. The helium nucleus has a high binding energy per nucleon and is more stable than some of the other nuclei close to it in the periodic table.
What is the mass defect of a mole of nuclei with 1.8 1015 Jmol binding?
2.0 x 10^-2 kg/mol
What type of energy is in nuclear reactions?
The binding energy in atomic nuclei. This energy is transmitted by the strong force.
The energy and particles given off during a nuclear reaction are called?
Radiation
Where does nuclear power receive its energy?
The energy of nuclear power comes from the binding energy that holds an atomic nucleus together. A heavy nucleus, usually uranium-235, splits into two smaller nuclei and releases three neutrons. These new nuclei have less binding energy than the original, and the excess energy is released as heat.
Is fission a nuclear force?
No. Fission is the splitting of atomic nuclei, which releases binding energy. That is the nuclear force.
Where did the atomic bomb get its power?
From the excess binding energy of the protons and neutrons in the atomic nuclei of certain isotopes.
What happened in fission when the products have less mass than the starting material?
The binding energy per nucleon varies in different nuclei, being a maximum in the region of iron and nickel, and getting progressively less as the heavier nuclei are approached, Therefore when a uranium nucleus splits into two nuclei of lighter elements, the total binding energy is increased, and this results in a loss of mass. The destroyed mass appears as energy, from the relation E = mc2. You can read more and see the binding energy graph in the link below. It is also evident why fusion of light nuclei like hydrogen also releases energy, as in this part of the graph binding energy increases as the nuclei get heavier.
What is a pairing energy?
A pairing energy is the extra binding energy associated with pairs of nucleons of the same kind - which results in nuclei which have odd numbers of protons or neutrons having a lower binding energy and being less stable than those with even numbers.
What is nuclear energy if it is not renewable and not a fossil fuel?
It is energy stored by ancient supernovas in heavy nuclei like Uranium, when the stars exploded.It is also energy stored by the Big Bang in light nuclei like Hydrogen.This energy is stored in the Strong Nuclear Force as excess Nuclear Binding Energy.
