1.	What dk you understand by, "The lack of deterinism in quantum theory"?
Answer» "The lack of determinism in quantum theory!" The behaviour of an electron orbitting a nucleus of an atom can not be predicted. There are different energy states within an atom varying from lower to higher. An electron can jump from lower energy state to higher energy state or the vice-versa.
