protons & neutrons

The proton has a mass equal to that of hydrogen atom, which is equal to 1.67 x 10 - 2 4 g or 1.0073 amu while it has an unit positive charge of +1.602 x 10 -19 ..

A proton can be thought of as a hydrogen atom that has lost its electron. Since the mass of an electron is small, the mass of a proton is equal to the mass of a hydrogen atom. As the mass of hydrogen atom is for all practical purposes 1 a.m.u., the relative mass of a proto..

Since the atom is electrically neutral there must be positively charged particles present in the atom to neutralize the negative charges of the electrons. Goldstein experimentally proved the existence of protons in the ato..

The Born Haber cycle can also be used to calculate the proton affinities (PA) of some bases. The proton affinity of a species X is defined as the energy released in the reaction: ..

It has been found that the stability of nucleus depends upon its neutron to proton (n/p) ratio. A plot of N (the neutron number) against Z (atomic number or number of protons) show that for stable nuclides upto Z = 20, N = 20 i.e., the relationship can be represented by ..
