How many isotopes does radium have?
Radium has today 33 isotopes and 12 nuclear isomers.
Are there any allotropes or isotopes of radium?
1. Radium has 45 isotopes and nuclear isomers. 2. Radium has no known today allotropes.
What is the protons of radium?
Radium has an atomic number of 88, which means it has 88 protons in its nucleus. This characteristic defines it as an element and determines its position on the periodic table. Radium is a radioactive alkaline earth metal, and its isotopes have various applications in medicine and industry.
What element does radium become once it has decayed?
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).
What is the first decay product of radium?
Radium decays in any of (at least) four different ways, depending on isotope and, in some cases, on luck, as some isotopes can decay in different ways. The most important way radium can decay is by alpha emission. Nearly all naturally occurring radium decays this way, and so do the majority of synthetic isotopes. In this case, radium emits an alpha particle, which can be regarded as a helium nucleus, and the daughter atom is radon. The isotope of radon is depends on the isotope of radium involved; the mass number of the radon is always equal to the mass number of the radium minus four. Some heavier radium isotopes undergo negative beta decay, in which case the decay products are an actinium atom and a negative beta particle, which can be viewed as an electron. Some lighter radium isotopes undergo positive beta decay, in which case the decay products are a francium atom, a positive beta particle, which can be viewed as a positron, and an electron type antineutrino. A few radium isotopes also rarely undergo what is called cluster decay, and the most important naturally occurring isotope, radium-226 is among these. Cluster decay involves emission of a nucleus larger than an alpha particle, and in the case of radium all known cluster decays emit carbon-14 nuclei. In this case, the daughter atom is lead, with a mass number that is 14 lower than the mass number of the parent. So radium-226 can emit a carbon-14 nucleus, leaving a lead-212 atom.

Which causes maximum radioactive contamination out of there sodium radium potassium?
Radium, by a big margin. Radium has no isotopes that are not radioactive, but no naturally occurring isotopes of potassium or sodium are radioactive.
Do they have treatments for radium?
Possible use of radium isotopes for the radiotherapy of some cancers.

How many radium is used in medecine?
Now radium is extremely rarely used for the radiotherapy of cancers; the isotopes 60Co and 137Cs are cheaper and more efficient.
Is radium treatment given everyday?
Today the radiotherapy wit radium is only rarely used; many other isotopes are more cheaper and efficient.
