Question

Are halogens positive or negative?

Answer 1

1. Halogens are Fluorine, Chlorine, Bromine, Iodine and Astatine.
2. They belong to the left-hand side of the periodic table in the 17^th group. They are non-metals.
3. Each halogen has seven electrons in its outermost (valence) shell. For acquiring stability each halogen takes up a single electron and acquires a negative charge.
4. They exist as halide ions. For example- Chloride ion $\left({\mathrm{Cl}}^{-}\right)$, Iodide ion $\left({\mathrm{I}}^{-}\right)$.
5. So, halogens are negatively charged.
