The radium nitride (Ra3N2) has a black color.
Radium is an element, with atomic number 88. The element radium is a radioactive alkaline earth metal that is the decay product of thorium, element number 90. (Thorium is, itself, the radioactive daughter of uranium.) Radium (226Ra, the isotope that is the result of the alpha decay of thorium) has a half-life of 1602 years, and the element acts chemically like the other +2 elements in group 2 of the periodic table. It is highly radioactive and dangerous. (Links are provided to the Wikipedia article on radium and also to a related question.)
Radium is only found in trace amounts in uranium ore. It is not a stable element, so it cannot be found by itself like other elements (say, oxygen) can.
That sounds like 714N, which is nitrogen. You almost certainly haven't taken a breath that wasn't mostly this odorless, colorless gas.
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
At room temperature radium is a solid metal.

Radium is the "heaviest known alkaline earth; it's chemical properties mostly resemble those of barium." "Like other alkaline earth metals, radium reacts violently with water to form radium hydroxide." This puts radium with Cs, Rb, K, Na, Li, Ba, Sr and Ca on the reactivity scale; in other words, highly reactive.Please see the links.
Radium is a group 2 metal, all of them are reactive, all of them react with air, (magnesium is reactive but passivates with a thin oxide film). Radium is just behaving like any other member of the group. They have 2 outer electrons that are readily lost to form ionic compounds.

To know everything about nitrogen, or any other specific element, you need to get a PhD in chemistry and then specialize in teh study of nitrogen, or any other specific element. It is not possible to provide "everything about nitrogen" is a site like this one.
radium has NO odor
We will find that nitrogen dioxide in air will react with water to form nitric acid. The equation looks like this: 3NO2 + H2O => 3HNO3 + NO
Radium is only found in trace amounts in uranium ore. It is not a stable element, so it cannot be found by itself like other elements (say, oxygen) can.
Nitrogen is an element all in itself. N2 is nitrogen gas, a diatomic particle like O2, oxygen gas.
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
Because it, like all other alkaline earth metals (except for Beryllium), reacts violently (heat of reaction approx. 9.0 Kcal./g per atom) with water to form radium hydroxide and hydrogen gas. source heat of reaction: The Radiochemistry of Radium, National Academy of Sciences National Research Council
