The element iodine would be expected to form covalent bond(s) in order to obey the octet rule. Use the octet rule to predict the formula of the compound that would form between iodine and hydrogen , if the molecule contains only one iodine atom and only single bonds are formed.

Answer:

HI (hydrogen iodide).

Explanation:

Hello,

In this case, since iodine is in group VIIA, it has seven valence electrons at its outer shell, which means that it only needs one bond to attain the octet. Moreover, since hydrogen has just one electron at its outer shell, one hydrogen turns out enough to obey the octet when hydrogen and iodine bond as shown below:

[tex]H-I[/tex]

Therefore, the required formula is:

[tex]HI[/tex]

Which is hydrogen iodide.

Best regards.
