I'm trying to split the strings of chemicals into their elements and numbers.
See this example
"Fe3O4" will be split into
I've tried using
StringSplit and various
_LowerCaseQ type patters but it isn't working. I've also tried using
StringSplit[#,""] to split everything and then finding the lower case characters and putting it back together but I haven't got it to work. Any solution would be greatly appreciated.
