They are what you call Halogens.The halogens exist ,at a room temperature,in all three states of matter:
Solid-Iodine,Astatine; Liquid-Bromine; Gas-Fluorine,Chlorine;
Don't they all exist in the three states of matter? Depending on the temperature...
The term gas is limited to those substances that exist in the gaseous state at room temperature and pressure. This means they have low density, take the shape of their container, and have molecules that are far apart. Gases can be compressed and expand to fill their container.
Hydrogen can exist in different states of matter depending on the temperature and pressure. At room temperature and pressure, hydrogen is a gas. At very low temperatures, it can become a liquid or a solid.
When two or more substances are combined, the temperature of the reaction may increase or decrease depending on the specific reaction. This change in temperature is due to the release or absorption of energy during the chemical reaction.
Lanthanides exist as solids at room temperature and pressure. They have metallic properties and are typically soft, malleable, and ductile.
Most substances can exist in any of the three states of matter, depending on their temperature. Water if the perfect example: water, steam, and ice.
Well everything has matter therefore, it is possible for it to be in all 3 states
At a given temperature practically all substances become a gas; it is a change of phase.
Solid, liquid, gaseous and plasma.
The variables that influence a state of matter include temperature and pressure. At higher temperatures, matter tends to exist in a gaseous state, while at lower temperatures, it may be solid or liquid. Increasing pressure can also cause substances to change states, such as from a gas to a liquid.
Carbon at room temperature is solid.

There are 2 states of matter. They are solids,liquids and gasses.
Most elements exist in the state of matter known as solids at room temperature and pressure. Some elements can also exist as liquids or gases depending on the conditions.
At "room temperature" - usually considered to be 68 degrees Fahrenheit - mercury is a liquid.
The term gas is limited to those substances that exist in the gaseous state at room temperature and pressure. This means they have low density, take the shape of their container, and have molecules that are far apart. Gases can be compressed and expand to fill their container.
