Guida verificata passo dopo passo1
Recall the common physical states of matter: solid, liquid, gas, and plasma.
Understand that nonmetals can exist in different states depending on temperature and pressure conditions.
At room temperature, many nonmetals such as sulfur and phosphorus are solids, while others like oxygen and nitrogen are gases.
Nonmetals rarely exist as liquids at room temperature because their melting points are usually either well below or above room temperature.
Plasma is a high-energy state of matter not commonly found under normal room temperature conditions for nonmetals.
