Solid
STP stands for standard temperature and pressure. Neon is a chemical element that is a gas at STP. The symbol for neon is Ne and it has the atomic number 10.
It's an aqueous solution.
Depends what you mean - your question is not clear - but consider :- At STP Oxygen and Hydrogen are two elements in the gaseous physical state BUT their compound Water is in the liquid state. At STP Oxygen is gaseous and Iron is solid BUT their compound is Iron Oxide is solid. So the answer is no.
The oxidation state of arsenic in H3AsO4 is +5. This is because each hydrogen atom has an oxidation state of +1 and each oxygen atom has an oxidation state of -2, leading to a total of +5 for arsenic to balance the charge of the compound.
The formula for arsenic(V) nitrite is As(NO2)5. This compound is formed by combining arsenic with nitrite ions, where the arsenic is in its +5 oxidation state.

It is a colourless gas at STP
Beryllium is a solid metal at room temperature.
At room temperature and pressure radium is a solid metal.
Arsenic has physical properties as it is a crystalline or metal-looking solid.
