Atomic mass unit is also referred as a.m.u . It is defined as the mass which is exactly 1/12th of the mass of a 6C12 atom. Thus, 1 a.m.u = 1/12th of mass of 6C12 = (1/12)*12g mol-1 /NA = 1g mol -1 / (6.022*1023mol-1) = 1.66*10-23g

It is a new fundamental particle which oscillates back and forth in between closed nucleons with a velocity which is comparable to the velocity of light. This particle is detected by various radiation experiments. These particles can be positively, negatively charged or can be electrically ...

If the alpha particles, protons and deuterons are imparted with the high velocity then they can be made more effective. For this purpose many instruments have been developed for increasing the speed of particles. E.O. Lawrence developed the most effective instrument for this which is known ...

What are nucleons? The protons and neutrons collectively present in the nucleus of an atom are called nucleons. The nucleons occupy very small space inside the nucleus. What are nuclear forces? Nuclear forces are attractive forces which exist in between protons and neutrons, neutron and neutron, proton and ...

The actual dimensions of the nucleus present in the atom are called nuclear size. Various experiments have been done to determine the size of nucleus (eg- Rutherford’s experiment). The nuclear size can be determined as- r = RoA1/3 Where r ...

The energy which is produced as a result of various nuclear processes is called nuclear energy. The nuclear energy can be produced by two types of nuclear reactions or processes 1. Nuclear Fission 2. Nuclear Fusion. The production of nuclear energy holds a powerful hope to ...

Nuclear chemistry is the subfield of general chemistry dealing with nuclear processes, radioactivity and nuclear properties of atoms. It deals with the composition of nuclear forces, nuclear reactions and radioactive materials. The discovery of radioactivity lead to the began of nuclear chemistry. Nuclear chemistry bases ...

Packing fraction is defined as a way of expressing the variation of isotopic mass from whole mass number (atomic mass). This fraction can have positive or can have negative sign. A positive packing fraction describes a tendency towards instability. A negative packing fraction means isotopic mass ...
