As we all have been knowing that Radium is an radioactive element or I can say radioactive metal (to be precise).The Radium releases radioactive particle -alpha particle,beta particle and gamma particle;during a nuclear decay and these particle ionise the substance around it.And this helps it to emit light.

∙ 14y agoToday radium has only limited applications in research laboratories, for example for the preparation of radon standard solutions, in neutron sources of the type Ra-Be, etc.
Possible use in radiotherapy of some cancers.
Radium was used in the past for luminescent painting of watches and other instruments, was used in toothpaste, cosmetics, etc. These applications are not permitted now because radium is strongly radioactive and dangerous.

When radium-226 decays to form radon-222 the radium nucleus emits a?
When Radium-226 decays to form Radon-222, the Radium nucleus emits an alpha particle. The atomic number goes down by 2, and the mass number goes down by 4, matching the atomic number and mass number of the alpha particle.
A black hole emits no light because of its?
a black hole emits no light because of its high gravity
What happens to atoms and their electrons while the entity emits light?
The electrons of the atom move closer to the nucleus while the atom emits light.
Is the light from an incandescent lamp monochromatic?
No, an incandescent bulb i.e. a bulb that emits light by the generation of heat, emits white light and is therefore not monochromatic. For a source to be monochromatic, the light emitted must be of a single wavelength.
What Does Radioactiveness mean?
A material that emits radiation Like Uranium, Plutonium, Radium, etc
When radium -226 decays to form radon -222 the radium nucleus emits?
When radium-226 decays to form radon-222, the radium nucleus emits a alpha particle.
