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.
Radiation occurs whenever something spreads out along the radii of the system. [You see where the word comes from.] Sound radiates, as does heat and light. Atomic radiation, â¦ or radioactivity also radiates out in all directions. Unless otherwise constrained. It occurs when a disintegration occurs within the nucleus of an atom. Radiation also occurs with populations of plants and animals. When introduced into a new environment, a species is said to radiate as it spreads out.
