Matter typically exists in one of three states: solid , liquid , or gas . ... Some substances exist as gases at room temperature (oxygen and carbon dioxide), while others, like water and mercury metal, exist as liquids. Most metals exist as solids at room temperature. All substances can exist in any of these three states.

The alkali metals are solids at room temperature (except for hydrogen), but have fairly low melting points: lithium melts at 181ºC, sodium at 98ºC, potassium at 63ºC, rubidium at 39ºC, and cesium at 28ºC. They are also relatively soft metals: sodium and potassium can be cut with a butter knife.

All metals except mercury are solids at room temperature. Both the high electrical conductivity and thermal conductivity come from the fact that one or more valence electrons is relatively free to travel throughout the solid material.

Metals: Substances that are hard solid at room temperature (except mercury), shiny, malleable, ductile, and good conductor of heat and electricity.

Solid is one of the three main states of matter, along with liquid and gas. Matter is the "stuff" of the universe, the atoms, molecules and ions that make up all physical substances. In a solid, these particles are packed closely together and are not free to move about within the substance.

Boron is a solid at room temperature. It is classified as a metalloid (which is neither a metal nor a nonmetal) and is generally brown or black in color.

I presume you mean “What elements are solid at room temperature (and pressure)”. All of them, except the gases hydrogen, nitrogen, oxygen, fluorine and chlorine, the “noble” gases helium, neon, argon, xenon, krypton and radon, and the liquids bromine and mercury.

Properties of Solids. Solid are characterized by structural rigidity and resistance to changes of shape or volume. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does expands to fill the entire volume available to it like a gas .

An ionic compound is most likely a solid at room temperature and pressure, whereas a covalent compound may be a solid, a liquid, or a gas. B Among the covalent compounds, those that are relatively nonpolar and have low molecular masses are most likely gases at room temperature and pressure.

Organic compounds can be gases, liquids, or solids at room temperature. Ionic compounds are all solids at room temperature with very high melting points. Organic compounds have relatively low melting points and boiling points.

Trans fats are semi-solid at room temperature owing the position of one (or more) of its chemical bonds being in the "trans-" rather than the "cis-" position. There are two types of trans fats: natural and artificial. Artificial trans fats start off as vegetable oils, which are liquid at room temperature.

Amazingly almost every element can exist as a solid, a liquid, and a gas - it all depends on the temperature. Mercury, for example, is generally found as a liquid but at -40 degrees Celsius it freezes and turns into a solid. And Mercury vapor (gas) is found in some particles of light.

The melting point of a solid is the temperature at which the vapor pressure of the liquid phase and the solid phase are equal and at equilibrium. ... The freezing point of water and other liquids may be the same temperature as the melting point. It won't be higher, but it could easily be lower.

At room temperature and normal atmospheric pressure, covalent compounds may exist as a solid, a liquid, or a gas, whereas ionic compounds exist only as solids. ... Ionic compounds exist in stable crystalline structures. Therefore, they have higher melting and boiling points compared to covalent compounds.

Foods that contain more saturated fat are usually solid at room temperature and are sometimes called “solid” fat.

Substances can change phase—often because of a temperature change. At low temperatures, most substances are solid; as the temperature increases, they become liquid; at higher temperatures still, they become gaseous. The process of a solid becoming a liquid is called melting.
