Are chemical elements always liquid?

No, chemical elements can exist in different physical states such as solid, liquid, or gas depending on factors like temperature and pressure. For example, mercury is a liquid element at room temperature, while elements like oxygen and carbon can exist as gases.


Are there metals in liquid state name them?

Mercury is the only metal that is a liquid at room temperature, despite it's high density.


What state are these elements likely to exist in at room temperature?

The state of elements at room temperature can vary based on their type. Most metals, such as iron and copper, are solid, while mercury is a notable exception, existing as a liquid. Nonmetals like oxygen and nitrogen are typically gases, while bromine is a liquid. Some elements, like phosphorus and sulfur, can exist as solids at room temperature.


Is ammonium nitrate aqueous?

Ammonium nitrate can be dissolved in water to form an aqueous solution, but it does not exist in a liquid state naturally.


Name the atoms or elements which exist in metastable state?

Atoms or elements can exist in a metastable state, including technetium (Tc), promethium (Pm), and uranium-235(U-235). These isotopes have relatively long half-lives, making them naturally occurring but unstable in the long term.
