Question

what are halogens ? Explain its properties?​

Answer 1

Halogens display physical and chemical properties typical of nonmetals. They have relatively low melting and boiling points that increase steadily down the group. Near room temperature, the halogens span all of the physical states: Fluorine and chlorine are gases, bromine is a display physical and chemical properties typical of nonmetals. They have relatively low melting and boiling points that increase steadily down the group. Near room temperature, the halogens span all of the physical states: Fluorine and chlorine are gases, bromine is a liquid, and iodine is a solid.

Answer 2

Explanation:

halogens [ hal- (“salt”) and -gen (“to produce") ], are the elements of group 17 in periodic table.

PROPERTIES

1. T hey are oxidizing agents; i.e., they raise the oxidation state, or oxidation number, of other elements—a property that used to be equated with combination with oxygen but that is now interpreted in terms of transfer of electrons from one atom to another.

2.The halogen elements all form compounds with hydrogen, the hydrogen halides. The energy of the hydrogen-halogen bond increases strongly from iodide to fluoride.

3.The halogen atoms carry seven valence electrons in their outermost electron shell.
