Respuesta :

Bromine(Br) is a Group 7A(17) element or compound that fits each description or use:(d) Element that is a liquid at room temperature.

The chemical element bromine has the atomic number 35 and the symbol Br. It is the third-lightest halogen, and at room temperature, it is a volatile red-brown liquid that easily evaporates to create a vapor of a similar color. Its characteristics fall in between those of iodine and chlorine.

In many different applications, including pesticides, medicines, dyes, agricultural chemicals, and chemical intermediates, bromine is used. For environmental concerns, some users are being phased out, but new ones are constantly being discovered.

Due to strong intermolecular interactions that prevent it from evaporating, bromine is a liquid at room temperature. Bromine may form diatomic molecules and has strong enough Van der Waals interactions. The volatile nature of bromine highlights its intensely invasive, suffocating, and disagreeable odor.
