the charge on an iodide ion is +7.
true
false

Explanation:

Iodide ion is formed when iodine gains an electron. Iodine is in Group 17 (halogen group). Elements in Group 17 gain 1 electron to achieve a stable electron configuration. When an atom gains an electron, it forms a negatively - charged ion. The charge on iodide ion (\(I^-\)) is \(- 1\), not \(+7\). The \(+7\) charge might be confused with the oxidation state of iodine in some compounds (e.g., in \(HIO_4\) where iodine has an oxidation state of \(+7\)), but the iodide ion specifically has a charge of \(-1\).

Answer:

B. False
