Radium is a solid, radon is a gas. Both are radioactive.
Radium is a radioactive chemical element, very dangerous, an alpha radiations emitter; radium is also a source of radon, by decay - also radioactive and dangerous gas.
Radium is a radioactive chemical element, very dangerous, an alpha radiations emitter; radium is also a source of radon, by decay - radon (gas) is also a radioactive element.
Radium is a solid, radioactive, alkaline earth metal.
Rutherfordium is radioactive and a solid, liquid, and gas;)
As radium is radioactive, radium chloride would also be radioactive. Any compounds make with any radioactive material are radioactive, and they cannot be "not" radioactive. Radioactive material doesn't really care if it is "alone" or in compound; it will be radioactive in any case.

Yes, radium and polonium are radioactive elements.

Radium, by a big margin. Radium has no isotopes that are not radioactive, but no naturally occurring isotopes of potassium or sodium are radioactive.
Yes. Radium is actually considered an alkaline earth metal. Its colour is nearly pure white, but when exposed to air, it turns black. Radium is also extremely radioactive. A link is provided to the Wikipedia article on radium.
Dust of the radioactive element Radium.
Radon is a very radioactive and dangerous gas.
Radium is very radioactive and toxic; the most simple effects are dermatological but an acute irradiation (or intoxication) can lead to death.
