Because they have fully filled outermost electronic configuration which is most stable & hence do not react easily. It reacts only with highly electronegative elements such as F & O. Mostly with XE.
Noble gases have completely filled energy levels. This evens out all repulsions between electrons, so there are no imbalances in any of the orbitals. Adding an electron to the stable configuration of a noble gas would require that the electron be placed in a higher energy level (n+1), which would require a significant amount of energy; similarly, the repulsions between the electrons would be out of balance if an electron were to be removed from the stable configuration; therefore, since one of these two types of scenarios would be required for a reaction to take place, noble gases are generally very stable and usually will not react.
An element
In a nuclear reaction, the nucleus of an atom undergoes a change. Common examples would be alpha decay, beta decay, fusion, and fusion. In each of those cases, different elements are formed in the process. This never happens in ordinary chemical reactions. In chemical reactions, it is the electrons that are involved , not the nucleus of the atom.
because it is radiation and radiation can not be affected by temperature and/or concentration.
In an ordinary chemical reaction, the mass of the products is equal to the mass of the reactants. Matter is conserved.
No, this would be contrary to the definition of an ordinary chemical reaction.
chemical reactions....actually it is matter (mass)
of course, by the intermediate of chemical reactions
An element
It involves the particles of the nucleus (protons and neutrons), not the electrons.
The law of Conservation of Mass states that in ordinary chemical reactions, mass can not be created or destroyed.
Only those involved in nuclear reactions. Ordinary chemical reaction can not effect this change.

I believe the question is Can bones be broken. The answer is yes. One major cause is the side-effects of the medicine used for arteriosclerosis.

For the first time, ordinary citizens could participate directly in government.
