When the symbol contains two letters the first letters is always and the second letter is always?
If the first letter is in Capitals and the second letter isn't, it is simply the name of one Element e.g. Feis Iron. If both the second and the first letters are in Captials there are two elements. e.g. CO which is Carbon Monoxide.Brad, U.K.

Why is the symbol for bromine BR on the periodic table?
While giving symbols to the elements the first letter of the name of the element was used. But in case of two or more elements with same initial the next elements were given symbols containing first two letters. Since boron has symbol B, so bromine got the symbol Br.
Of the first 103 elements how many have two letters in their symbols?
Not all elements can be identified by a single letter. For example, Carbon (C) and Chlorine (Cl) both start with a "C" and have "C"'s in their symbols. Another letter had to be added to distinguish the two. Also, the Periodic Table has over 100 elements and there would not be enough letters to cover them all if they were only single letters.

What is the symbol of neon?
Apart from symbols taken from their ancient names (like Ag for Silver - from Argentum, and K for potassium from Kalium) almost all other symbols are taken from the element's name - the first letter and, where necessary, another letter too - usually the next one. So C is Carbon, but when Calcium was discovered, it could not be give the symbol C as well, so it was given the symbol Ca. In the same way Hydrogen has the symbol H, but Helium cannot be given the symbol H too, so it has the symbol He, being the first two letters of its name. If there are two elements with the same two first letters (like magnesium and manganese) then another two letters are chosen instead - in this case the first and third letters rather than the first two - making the symbol of magnesium Mg, and that of manganese Mn. Similarly, for neon, N is the symbol for Nitrogen, and so Ne was chosen for Neon, being the first two letters of the name.
