Question

write the balanced nuclear equation for the radioactive decay of radium-226 to give radon-222, and determine the type of decay

Answer 1

226Ra88→222Rn86+4He2

Explanation:

An α-particle usually consists of a helium nucleus which indicates the type of decay that was undergone in this radioactive process.

During α-decay(alpha decay), an atomic nucleus emits an alpha particle.
