Answer 1

Answer:

ANSWER

The end product of 23290Th is 20882Pb. The number of alpha and beta particles emitted are respectively 6,4.

A beta particle, also called beta ray or beta radiation, (symbol β) is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay. There are two forms of beta decay, β− decay and β+ decay, which produce electrons and positrons respectively. Alpha decay occurs when a nucleus is unstable because it has too many protons. The Figure below shows what happens during alpha decay. The nucleus emits an alpha particle and energy. An alpha particle consists of two protons and two neutrons, which is actually a helium nucleus.
