Which of the following statement is /are correct regarding nucleus of an atom ?

Answer»

As number of protons increases in the nucleus, the number of neutrons REQUIRED for overcoming proton-proton repulsions also increase.
Projectile capture reactions involving proton as projectile can occur with slow moving proton also.
When `._(92)^(235) U ` undergoes FISSION reaction to from `._(36)Kr^(90) & ._(56)Ba^(142)` four neutrons are produced per Uraninum atom.
Gamma radiations can be emitted only along with `alpha ` or `beta` - decay and not alone.

Solution :(A) THEORY base
(B) slow moving proton will not capture by the nucleus becose it will be repal be the nucleus
(C) `._(92)^(235)U+._(0)n^(1) rarr .-(36)Kr^(90) +._(56)Ba^(142)+4_(0)n^(1)`
(D) nucleus always release `gamma` ray during `alpha` , `beta` decay.
