Suppose we consider a large number of continers each containing initially `10000` atoms of a radioactive material with a half life of `1` year. After `1` year.

A

all the containers will have 5000 atoms of the material.

B

all the containers will contain the same number of atoms of the material but that number will only be approximately 5000

C

the containers will in general have different number of the atoms of the material but their average will be close to 5000

D

none of containers can have more than 5000 atoms.

Text Solution

Verified by Experts

The correct Answer is:
c
Since half life of the material is 1 year , therefore , after 1 year, half the number of atoms will decay on an average . The containers will in general have different numbers of the atoms of the material but their average will be close to 5000.
