Question

Are halogens positive or negative?

Answer 1

Hint: The elements which are present in the VIIA group are called halogens. All halogens are nonmetals in nature. The name halogen itself indicates that they are having a good capability to form salt with metals.

Complete step-by-step answer:- In the question it is asked are halogens positive or negative.
- Halogens forms salt with metals very easily.
- We know that metals will lose electrons very easily.
- The electrons which are emitted by the metals are going to be accepted by the halogens.
- Therefore halogens are the elements that accept electrons and possess negative charge.
- Halogens need only one electron to get inert gas electronic configuration.
- Therefore halogens accept electrons very easily from the metals.
- There are five elements in group VIIA and they are fluorine, chlorine, bromine, iodine, and astatine.
- All halogens are generally only one electron from others.

Additional information:
- Halogens are highly toxic in nature.
- Halogens are poor conductors of electricity because of the absence of free electrons.
- Halogens have low melting point and low boiling points.

Note: All halogens exist in nature in linear form means in linear structure. Halogens are going to exist in nature in dimeric (${{F}_{2}},C{{l}_{2}},B{{r}_{2}},{{I}_{2}}$) form. Halogens only form one single bond with other elements. The reactivity of the halogens decreases as we are moving from top to bottom in the periodic table. Among the halogens fluorine has high electronegativity and is the most reactive element in nature.
