Question

The probability of decay of a radioactive
element depends on
i. the age of nucleus
ii. the presence of catalyst
11i. pressure
iv. temperature
(A) only i. and iv (B) all of these
(C) only ii. And iii. (D) none of these​

Answer 1

it depend un the in stable ayomic nucleous........

if it help then plz mark it as brainliest ans....

Answer 2

Answer:

i) the age of nucleus

Explanation:

Given that,

The probability of decay of a radioactive

element depends on

i) the age of nucleus

ii) the presence of catalyst

iii) pressure

iv) temperature

As per given data,

The probability of decay of a radioactive element depends on the age of nucleus.

Therefore, option (i) the age of nucleus is the right answer.

The probability of decay of a radioactive elements does not depends on pressure, temperature and the present of catalyst.

They are involved in the alter the rate of reaction on atomic level.

But the radioactive decay is phenomenon of inside of atom.

The energy difference between the two quantum levels involved in the transition corresponds to the decay energy.

This decay energy appears in the form of electromagnetic radiation and as the kinetic energy of the products. The mode of radioactive decay is dependent upon the particular nuclide involved.
