Question

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

Answer 1

X 86 206

Step-by-step 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
