Each element in
the Periodic Table has been given a 1, 2 or 3 letter symbol
collectively called Periodic Symbols. The
first letter of the Periodic symbols is always a capital letter,
for example, H for hydrogen, C for carbon, N for nitrogen. If
there is a second letter or third letter in the symbol it is a
lower case letter for example, He for Helium, Uuh for Ununhexium. |
