Which substance is most likely to exist as a solid at room temperature?

Which substance is most likely to exist as a solid at room temperature?

ionic compound
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.

What is liquid at room temperature?

Bromine is the only non-metal that is in liquid at room temperature. It is one of the only two elements on the periodic table that are liquids at room temperature other than Mercury.

What are 3 substances that are liquids at room temperature?

The only liquid elements at standard temperature and pressure are bromine (Br) and mercury (Hg). Although, elements caesium (Cs), rubidium (Rb), Francium (Fr) and Gallium (Ga) become liquid at or just above room temperature.

What are 3 substances that are gases at room temperature?

Elemental hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), and chlorine (Cl, element 17) are all gases at room temperature, and are found as diatomic molecules (H2, N2, O2, F2, Cl2).

Is bromine a liquid at room temperature?

Bromine (Br, element 35), also found as a diatomic molecule (Br2), is a liquid at room temperature, solidifying at -7.2ºC.

How do you know if a substance is liquid at room temperature?

If the normal melting point of a substance is below room temperature, the substance is a liquid at room temperature. Benzene melts at 6°C and boils at 80°C; it is a liquid at room temperature. If both the normal melting point and the normal boiling point are above room temperature, the substance is a solid.

Which of the 4 substances will be a liquid at room temperature?

Are fats liquid at room temperature?

The division into fats and oils is arbitrary and depends on the physical state of these molecules at room temperature. Those molecules that are usually solid at room temperature (plant or animal) are termed fats, while those that are liquids at room temperature are termed oils.

Why are some substances gases at room temperature?

Each substance is different however, as you have pointed out. Gold is solid at room temperature, mercury is a liquid, and neon is a gas. The reason for the difference is that they all have different elemental properties. Since there are no forces, they are free to move around and, therefore, are a gas.

Is nh3 a gas at room temperature?

At room temperature, ammonia is a colorless, highly irritating gas with a pungent, suffocating odor.

Is chlorine a liquid at room temperature?

Chlorine is a greenish yellow gas at room temperature and atmospheric pressure. It is two and a half times heavier than air. It becomes a liquid at −34 °C (−29 °F).

Why is fluorine gas at room temperature?

In fluorine, the electrons are tightly held to the nuclei. The electrons have little chance to wander to one side of the molecule, so the London dispersion forces are relatively weak. At a low enough temperature the molecules will all be solids. At a high enough temperature they will all be gases.

Are there any elements that are liquids at room temperature?

At this temperature and ordinary pressure, only two elements are liquids: Bromine (symbol Br and atomic number 35) and mercury (symbol Hg and atomic number 80) are both liquids at room temperature.

Are there any gases that are found at room temperature?

Elemental hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), and chlorine (Cl, element 17) are all gases at room temperature, and are found as diatomic molecules (H2, N2, O2, F2, Cl2).

Which is an example of an element at room temperature?

That state of matter of an element may be predicted based on its phase diagram. While temperature is an easily controlled factor, manipulating pressure is another way to cause a phase change. When pressure is controlled, other pure elements may be found at room temperature. An example is the halogen, chlorine.

Are there any elements that melt at room temperature?

Francium, cesium, gallium, and rubidium are four elements that melt at temperatures slightly higher than room temperature. Francium (symbol Fr and atomic number 87), a radioactive and reactive metal, melts around 300 K. Francium is the most electropositive of all the elements.
