What does the symbal OH stand for on the periodic table?

What is 'oh' ? If you mean 'OH' , This is the hydroxide anion and is correctly written as 'OH^-' , because it is a charged species. The hydroxide anion is composed of 1 x oxygen and 1 x hydrogen atoms and 1 x excess electron. You will find Hydrogen (H) and Oxygen(O) separately on the Periodic Table. Also when writing up chemical symbols, please follow the following rules ; - #1 Single letter elements ALWAYS have a capital letter . #2 Two letter elements have a capital to start and ALWAYS a small case letter as the second letter. These are the international standard, followed world-wide. Oh!!!! 'oh' does not mean anything chemically.
