`._(92)U^(235)` is `alpha` (alpha) active. Then in a large quantity of the element:

Options

A. The probability of a nucleus disintegrating during one second is lower is the first half life and greater in the fifth life
B. The probability of a nuelcues disintegrating during one second remains constant for all time.
C. Quite an appreciable quantity of `U^(235)` will remain even the average life
D. The energy of the emitted `'alpha'` paticle is less than the disintegration energy of the `U_(235)` nucleus.

Answer

B, C, D

Explanation

The probability of decay in 1 sec is the decay constant `D`, which remains constant after average lice `37%` of nuclei remain undecayed part of energy of disintegration is taken by the recoiling daughter nucleus.
