Question

What is radioactive decay ??
with example ​

Answer 1

Answer:

Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles or photons.

for example the decay chain that begins with Uranium-238 culminates in Lead-206, after forming intermediates such as Uranium-234, Thorium-230, Radium-226, and Radon-222. Also called the "decay series.". Each series has its own unique decay chain. The decay products within the chain are always radioactive.

Answer 2

Answer:

particles and energy called radiation are release by atoms of the radioactive element....with alpha,bita,gyama decay the element change..The first example is alpha decay where the parent isU-238 and the daughter is Th-234
