solid...
Atoms of all elements exist in the state of matter known as the gas phase.
Carbon at room temperature is solid.
Most elements are solids when they are at very low temperatures.
The standard temperature after IUPAC is 0 oC.
Indium can be solid, liquid or gas. At room temperature, indium is a solid.
Most metals at room temperature are in the solid phase. Gold is the most malleable and ductile of all known metals.
state or phase
The phase of matter for each element can be determined based on its melting point and boiling point. Elements with low melting and boiling points, such as hydrogen and helium, are typically gases at room temperature. Elements with higher melting and boiling points, such as iron and aluminum, are typically solids at room temperature. Elements that are in between, like mercury, can be liquids at room temperature.
Bromine (Br) and mercury (Hg) are the only two liquid elements on the periodic table. (at room temperature and normal pressure that is)
The butane phase diagram shows how butane can exist as a solid, liquid, or gas depending on the temperature and pressure. It illustrates the boundaries between these states and the conditions where each state is stable.
Non-metals typically exist in solid or gas phases at room temperature, with some non-metals like iodine and bromine being in a liquid phase. Examples of non-metals in the solid phase include sulfur, carbon, and phosphorus.
Covalent.Every compound can exist as a solid, liquid, or gas, given the right temperature and pressure. This is also true of every element, with the single exception of helium, which has no solid phase, no matter how cold it is. Helium is unique.
