\(O\)
Iodine
\(I\)
 
2. If the name of an element has the same letter as another, use the first and second letter of their English name—the first letter in upper case and the second letter in lower case. For example,

3. If the first letter or first two letters of the element is the same as another, use the first and second or third letter of the English name.
