Interpretation: Name and formula of two elements that are liquid at
Concept Introduction: Every matter is made of chemicals; the importance of chemistry is that it's the study of everything. Chemistry is all about how something interacts to affect the structure, composition, as well as knowing properties of substances.

Answer to Problem 8RQ
The name of elements: Mercury (Hg) and Bromine
Explanation of Solution
A substance which is made entirely from one type of atom, called element.
Matter that is made of more lightly packed particles, called Liquid.The arrangement of the liquid molecules is not fixed. They can change their position according to the container. The intermolecular space is found in the liquid molecules. They have the intermolecular attraction due to this the liquid can flow.
In gases, atoms & molecules are much more spread out as compared to solids and liquids. Gases are not rigid as compare to liquid and solid. They do not have definite shape and definite volume.
The band gap energy decreases as the temperature increases. According to the periodic table, there are only two elements, Mercury (Hg) and Bromine
Mercury has a melting point of
