Why do elements have one capital letter and others have a capital letter and one or two lowercase?
All elements have a capital letter.... often taken from the first letter of their name in Latin. Some only needed one letter because there was no confusion when they were being written.... Hydrogen was the only H at first, then when Helium was discovered the custom was that H stood for Hydrogen so it couldn't easily be changed, so Helium became He.... and so on. There are no element symbols having 2 lowercase letters.

Why don't some chemical symbols not start with just their capital letter?
One reason that elements don't simply use the capital letter is that there are 118 known elements, but our alphabet only has 26 letters. Additionally, some elements have the same beginning letter, so we must use something else for the symbol. Carbon (C), copper (Cu), cobalt (Co), and calcium (Ca) can't all be represented by the same symbol. Finally, some chemical symbols are based on the names of elements in other languages, often Latin or Greek. For example lead's symbol, Pb comes from its Latin name, plumbum.
