At room temperature and pressure radium is a solid metal.
At room temperature and pressure radium is a solid metal.
The decay of radium to lead is a nuclear change, not a chemical or physical change. It involves the transformation of radium atoms into lead atoms through the process of radioactive decay. This change is due to the emission of alpha particles and does not involve any chemical reactions or changes in the physical state of the substances.
Radium can undergo several physical changes, including solidification, where it transitions from a gaseous or liquid state to a solid form. It can also experience melting when heated above its melting point, changing from solid to liquid. Additionally, radium can undergo sublimation, directly transitioning from solid to gas without becoming liquid at certain conditions. Lastly, radium may undergo thermal expansion, where its volume increases as it is heated, affecting its physical dimensions.
The most common state of matter for radium is solid, specifically a metallic solid. Radium is a radioactive element that is typically found in the solid form due to its high atomic number and density.

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.
Gas at STP.
