1.	When a nucleus in an atom undergoes a radioactive decay, the electronic energy levels of the atomA. do not change for any type of radioactivityB. change for `alpha` and `beta` radioactivity but not for `gamma`-radioactivityC. change for `alpha`-radioactivity but not for othersD. change for `beta`-radioactivity but not for others
Answer» Correct Answer - b As an alpha particle carries 2 units of positive charge, and a beta particle carries one unit of negative charge and `gamma` particle carries no charge , therefore electronic energy levels of the atom change for `alpha` and `beta` radioactivity , but not for `gamma`- radioactivity .

A bone containing `200 g` carbon-14 has `beta`-decay rate of `375` decay/min. Calculate the time that has elapsed since the death of the living one. Given the rate of decay for the living organism is equal to `15` decay per min per gram of carbon and half-life of carbon-14 is `5730 years`.A. 22920 yrB. 11460 yrC. 17190 yrD. None of these
Fusion processes, like combining two deuterons to form a He nucleus are impossible at ordinary temperatures and pressure. The reasons for this can be traced to the fact: (a) nuclear forces have short range. (b) nuclei are positively charged. (c) the original nuclei must be completely ionized before fusion can take place. (d) the original nuclei must first break up before combining with each other.
