Question

The radioactive atom R 88 210 a is an alpha emitter. What nucleus does it produce?

Answer 1

Answer:

X 86 206

Explanation:

Radioactive atoms are nuclei that can under go disintegration to emit either an alpha particle, beta particle or gamma radiation. The process could be spontaneous or stimulated.

When a radioactive atom R 88 210 emits alpha particle, it would produce an element with atomic number 86 and mass number 206 i.e X 86 206. An alpha particle is usually a helium nucleus.

                     $R^{210}$ ⇒ $x^{206}$ + $He^{4}$ + energy
