When most radioactive atoms “spontaneously” decay to a more stable form the “additional” energy is converted to radiation with the emission of radioactive particles.
<h3>What is radioactivity?</h3>
Radioactivity is the spontaneous decay of the nucleus of an atom with the emission of radiation and nuclear particles.
Elements that spontaneously decay are called radioactive elements.
When these radioactive elements decay, they form more stable isotopes or elements.
The spontaneous decay of atoms of radioactive elements is in order for the nucleus of the atom to become stable and non-radioactive.

16 tiles x 0.80 = $12.80
If you have two 100 dollar bills, you have 200 dollars.
$200 - $12.80 = $187.20
Answer:
100ml of a stock 50% KNO3 solutions are needed to prepare 250ml of a 20% KNO3 solution.
Explanation:
In the given question it is mentioned that
S1=50%
V2=250ml
S2= 20%
We all know that
V1S1=V2S2
∴V1= V2×S2÷S1
∴V1= V2S2×1/S1
∴V1= 250×20÷50
∴V1= 100ml
