1. Radium has 45 isotopes and nuclear isomers.
2. Radium has no known today allotropes.
Radium has today 33 isotopes and 12 nuclear isomers.
Radium has today 33 isotopes and 12 nuclear isomers.
If they are in different physical form they are ALLOTROPES. If they are in different atomic form they are ISOTOPES. e.g. Allotropes [ Graphite, diamond and buckyballs* buckminster Fullerene) are allotropes of carbon. They appear different because the arrangment of the atomis is different. Isotopes Carbon 12 , Carbon-13, Carbon-14 are isotopes of carbon , because they have a different number of neutrons in the nucleus.

The first name was radium; some isotopes had in the past other names.

Radium, by a big margin. Radium has no isotopes that are not radioactive, but no naturally occurring isotopes of potassium or sodium are radioactive.

Possible use of radium isotopes for the radiotherapy of some cancers.

It isn't used for anything anymore--they have better, safer isotopes to do the things radium was once used for.
They are all forms of a given chemical element. Example for sulfur: - S6, S7, S7, S7, S12, S18, etc. are allotropes of sulfur; but the atomic number (number of protons and electrons) of the sulfur atoms is the same. - sulfur has natural or artificial isotopes; but the atomic number (number of protons and electrons) of the sulfur isotopes is the same. - an isomer is 43mS; but the atomic number (number of protons and electrons) of this sulfur isomer atoms is the same as for other isotopes.
All the isotopes from the decay chains exist in these rocks. The most important are the dangerous isotopes of radium and radon.
Radium undergoes radioactive decay, specifically alpha decay, to become radon. Radium-226 (226Ra) will undergo alpha decay releasing that alpha particle, which is a helium-4 nucleus, to become radon-222 (222Rn).
