Step 1 : Introduction to the question "Which of these chemical elements is represented on the atomic table by a single letter?"
Every element in the Periodic Table has been given a unique 1, 2 or 3 letter symbol. The first letter of an element symbol is always a capital letter. Many of the element symbols are quickly remembered with just one letter. These elements are: B for Boron, C for Carbon, F for Fluorine, H for Hydrogen, I for Iodine, K for Potassium, N for Nitrogen, O for Oxygen, P for Phosphorus, S for Sulfur, U for Uranium, V for Vanadium, W for Tungsten, and Y for Yttrium. Any subsequent letters, which make up the element symbols, are expressed in lower case, for example the chemical symbol for Gold is Au, Silver is Ag, and Sodium is Na.
