`._(7)^(14)N` is attacked by doubly charged helium ion, it emits a proton and:

""_(7) ^(14)N is given . Calculate the number of protons m neutrons and electrons in Nitrogen .

._(7)^(14)N and ._(6)^(14)C are isobars

._(7)^(14)N and ._(6)^(14)C are isobars

The first nuclear reaction ever observed was by ernest Rutherford in 1919. It was triggered by alpha particles incident on an isotope of nitrogen ._(7)^(14) N. He observed a proton was emitted along with another element x. Let us assume that ._(7)^(14) N nucleus was initially stationary. For this reaction to occur, alpha-particle must touch the nitrogen nucleus. The distance between their centres at this moment is d. For this problem, we will neglect the effect of outer electrons in ._(7)^(14) N. Symbols have their usual meanings. X is an isotope of

A hydrogen atom makes a transition from n=2 to n=1 and emits a photon. This photon strikes a doubly ionized lithium atom (Z=3) in excited state and completely removes the orbiting electron. The least quantum number for the excited stated of the ion for the process is:
