text: Astatine was first produced by bombarding bismuth-209 with energetic alpha particles, and this is still the major route used to create the relatively long-lived isotopes astatine-209 through astatine-211.
text: It has the distinction of being the rarest natural element found in the Earth's crust, as it is only produced from radioactive decay of even heavier elements.
text: Astatine may be produced by bombarding bismuth with energetic alpha particles to produce At-209, At-210, and At-211.

text: Astatine can be produced by using alpha particles to bombard bismuth.
text: Astatine can be produced by bombarding bismuth with energetic alpha particles to obtain the relatively long-lived 209-211At, which can be distilled from the target by heating in air.
