Not known today
Radium has a hardness of around 1.5-2.5 on the Mohs scale, which is relatively soft compared to many other minerals.
"Illuminate your world with Radium!" "Shine bright like Radium!" "Glowing brilliance with Radium." "Radiant energy, powered by Radium."
The first name was radium; some isotopes had in the past other names.
No plural for radium.
Radium primarily forms compounds with oxygen, such as radium oxide (RaO), radium peroxide (RaO2), and radium hydroxide (Ra(OH)2). It can also form compounds with other elements, such as radium chloride (RaCl2) and radium sulfate (RaSO4). These compounds are generally highly radioactive due to the nature of radium as a radioactive element.

Radon is a colorless, odorless, tasteless gas, so it does not have a hardness like a mineral or metal. Instead, radon is classified based on its radioactivity and health impact due to its ability to emit ionizing radiation.
radium has NO odor
radium was not invented, it was discovered.
The chemical symbol of radium is Ra.
In English, radium is pronounced as "ray-dee-uhm."
