Determine the number of electrons in the outer ring (valence electrons) for each of the following elements:

- Phosphorus
- Potassium
- Oxygen
- Iodine
- Gold
- Bromine
- Sulfur
- Cobalt

Phosphorus = 5 Potassium = 1 Oxygen = 6 Iodine = 7 Gold = (a transition metal) Bromine = 7 Sulfur = 6 Cobalt = (a transition metal)
For future reference, look at the group number along the top, it tells you :)

The number of valence electrons varies by element: Phosphorus has 5, Potassium has 1, Oxygen has 6, Iodine has 7, Gold typically has 1, Bromine has 7, Sulfur has 6, and Cobalt has 2. Most elements' valence electrons correspond to their group number in the periodic table. Transition metals like Gold and Cobalt may have more complex valence counts according to their electron configurations.
