# How many single bonds can iodine form?

Jun 25, 2016

Iodine can form 1, 3, 5, or 7 covalent bonds.

#### Explanation:

Iodine has seven valence electrons, so it typically forms only one covalent bond.

An example is $\text{H-I}$.

However, highly electronegative elements like fluorine, chlorine, and oxygen can cause iodine to form 3, 5, or 7 covalent bonds.

Examples are ${\text{IF"_3, "IF}}_{5}$, and ${\text{IF}}_{7}$.
