Which of the following is correct regarding radioactive process ?   (i) Despite the strength of the forces that hold them togther, many nucleides are unstable and spontaneously alter temselves through radioactive decay sometime through radioactive decay somtimes through a series of such decays, untiall thry reach stable comfigurations   (ii) When a nucleus undergoes `alpha` or `beta` decay, its atomic number `Z` chnges and it becomes the nucleus of a different element   The energy liberated during radioactive decay comes form within individual nuclei without external exciatation, unlike the case of atomic radiation   (iv) Radioactive decay is a statistical process that obeys the laws of chance. no cause effect relationship is involved in the decay of a particular nucleus, only a certain probaility per unit time
