Explanation:
Detailed explanation-1: -As you learned, scientists standardized the short-hand way we represent elements, by their chemical symbol. One of the main reasons this was developed was because using letters was the easiest way to represent the elements. Another reason that we use chemical symbols is to allow us to write chemical formulas easily.
Detailed explanation-2: -Since the formulas for chemical compounds are written by placing the symbols next to each other (with number subscript sometimes), the capital letter shows that a new element is being referenced. The capital letter serves to separate chemical symbols in the same way that spaces separate words in a sentence.
