Radon is a radioactive natural chemical element originating as a decay product in the uranium, thorium and actinium series; thoron is the old name of the isotope 220Rn.
The gaseous products of a disintegrating radioactive substance such as thoron or radon usually include isotopes of helium or polonium. These isotopes are formed as a result of radioactive decay and are emitted in the form of gas. They can pose a health risk if inhaled, as they are radioactive and can accumulate in the lungs.
no
earth is the only planet where the same substance can exist in gaseous , liquid , and solid form
yes
evaporation!
From solid to liquid, from liquid to gaseous, from gaseous to liquid, from liquid to solid, and in sublimation from solid to gaseous or the reverse, chemical properties do not change.
no
no
Yes, all of them.
Nope, but it is a colorless, radioactive, inert gaseous element formed by the radioactive decay of radium.
if the temperature of the substance is raised then the kinetic energy of the gaseous particles will also increase....
Acid rain is acidic.
when a substance exists as a liquid or solid under ordinary conditions its gaseous phase is called a vapor
It is radon that we see formed from the decay of naturally radioactive substances in the earth's crust.
water is the substance
Any gaseous substance that can kill you.
Oxygen
No.
