its a redish silvery colour
The radium nitride (Ra3N2) has a black color.
At room temperature radium is a solid metal.
Radium glows in the dark and is in glow bands
radium has NO odor
Radium is dangerous to feel but i'm assuming it feels smooth like a pebble
Oxygen (air) turns Radium black. Radium-Bromide makes air glow green like neon.
Radium has an oxidation state of +2, Oxygen has an oxidation state of -2.....so it'll look like this Skeleton equation: Ra + O2 --> RaO.... Balanced equation 2Ra + O2---> 2RaO
Radium oxide has never been characterised. As radium is group 2 metal with chemistry like barium, radium oxide is expected to be ionic.

Radium glows in the dark and is radioactive. When it decays into Radon gas, it emits alpha particles. It is fairly close to its compound radiumchlorite because like radium, it also decays emiting alpha particles. However, radiumchlorite is used to help cure canser. Overal, radium is like its most comon compound but can also have properties not related to its compounds at all.
Radium is modestly malleable if it is heated a bit. It will behave in a way similar to magnesium, which is a group 2 alkali earth metal like radium. But don't look for radium to be hammered or rolled into something. Radium is highly radioactive, and it isn't something that you want to be around, or to have around you. A link to the Wikipedia article on radium is provided. But there isn't a lot of information
