Question

what is the appropiate nuclear equation for each of the following descripitons.

1.) radon-222, an alpha particle emitter, is a naturally occuring isotope found in some basements.

2.) chemist glen seaborg and his associates created 10 new elements between 1940 and 1961. Americium, one of the new elements, was formed by bombarding plutonium-239 with neutrons to produce americium 241 and beta particle.

3.) a nuclear fission reaction occurs when a U-235 nucleus is bombarded by a neutron. the products are Xe-143, 3 neutrons, and a strontium isotope.

Explanation / Answer

1. Radon-222 has a half-life of about 3.8 days. It decays into polonium-218 through alpha decay.

86Rn222 = 84Po218 + 2He4

2. 94Pu239 + 2. 0n1 = 95Am241 + -1e0

3. 92U235 + 0n1 = 54Xe143 + 38Sr90 + 3. 0n1
