The mass of the diamond is 7.056 × 10⁻³ oz.
<em>No. of grams</em> = 1 ct × (200 mg/1 ct) × (1 g/1000 mg) = 0.2 g
<em>No. of pounds</em> = 0.2 g × (1 kg/1000 g) × (2.205 lb/1 kg) = 4.410 × 10⁻⁴ lb
<em>No. of ounces</em> = 4.410 × 10⁻⁴ lb × (16 oz/1 lb) = 7.056 × 10⁻³ oz
Iodine is one of seven elements that usually form as diatomic molecules. These other "diatomics" are

and

. They typically bond to themselves.
Iodine has seven valence electrons. Using valence shell electron pair repulsion (VSEPR) theory, we can predict the Lewis dot structure for

. We see there are fourteen electrons, and we can make a covalent bond, leaving three lone pairs on each atom. The bond replaces two electrons, so the number of electrons shared is two.
