Question

Que. Life of 20 gram Po is 102 years . how many particles are emitted in 1 sec from 2 mg sample Po ?
​

Answer 1

Answer:

Unstable nuclei decay. However, some nuclides decay faster than others. For example, radium and polonium, discovered by the Curies, decay faster than uranium. This means they have shorter lifetimes, producing a greater rate of decay. In this section we explore half-life and activity, the quantitative terms for lifetime and rate of decay.

please mark as brain list dude ✌️✌️

Answer 2

Answer:

0.344 mg decays in 62 years

Hope it helps u !!
