Help me please. Need help in science i don't understand.
Kaylis [27]

The decay of Francium produces radium-223 (Ra-223) through a beta decay or into astatine-219 through an alpha decay. The atomic number of Francium is 87, and that of Astatine is 85.

<h3>What is beta decay?</h3>

Beta decay is a type of radioactive decay in which a beta ray is emitted from the nucleus of an atom. During the beta decay, a proton in the nucleus is transformed into a neutron and vice versa which results into change in the number of proton in the nucleus. If a proton is converted to a neutron, then it is said to be β+ decay. And, if a neutron is converted to a proton, then it is said to be β– decay.

In this reaction, an atom of Francium (Fr-223) is undergoing a beta decay to produce radium (Ra-88) by the conversion of a neutron into a proton.
