Which pair of thyroid hormones contains iodine and are essential for metabolism?

Thyroxine (T4) and triiodothyronine (T3)

A common medical diagnostic and therapeutic use of radioactive iodine (I-131) is for treating:

Hyperthyroidism and thyroid cancer

In iodized salt programs, which iodine-containing compound is most commonly added to table salt to prevent deficiency?

Sodium iodide (NaI) or potassium iodide (KI)

Elementary iodine crystals (I2)

Which chemical property explains why iodine (I2) is less reactive than the lighter halogens chlorine and fluorine?

Higher electronegativity than chlorine

Stronger I–I bond than Cl–Cl bond

Larger atomic radius and lower oxidizing power

Existence only in a noble-gas-like inert state
