- P is white solid. When heated produces white fumes (sublime).
- P and R on warming produce an alkaline gas.
- On adding water to T, heat is evolved and R is formed.
- Q burns brightly in the air to form T.
- When S is heated, it gives off brown fumes and leaves a black residue of U.
- A solution of S is formed by warming U with dilute nitric acid.
- V is a gaseous non-metallic element that reacts with hydrogen to form W.
- A solution of W will neutralize the solution of R.
The metallic character of the element decreases moving across a period from left to the right.
