The average typing speed for boys is 44 words per minute. This is slightly faster than for girls, who clock in at 37 wpm, a full 7 word per minute slower. This seems a little odd, because statistics show that girls actually enjoy practicing their typing skills more than boys do.
  Radioactive decay is a natural process that occurs because a given atomic nucleus is unstable. The instability in the nucleus will eventually result in some kind of nucl â¦ ear change (depending on the atom), and we call this radioactive or nuclear decay.adioactive decay is the spontaneous change or disintegration of an unstable atomic nucleus as it transforms itself to lose energy.
When the number of protons changes, an atom of a different chemical element is created. The first decay processes to be discovered were alpha decay, beta decay, and gamma decay. Alpha decay occurs when the nucleus ejects an alpha particle (helium nucleus).
