Answer

Brief Explanations:

  1. Chemical symbols can be one - or two - letter abbreviations for elements. For example, hydrogen is H (one - letter), and calcium is Ca (two - letter), so the symbol is not always a single letter.
  2. Some chemical symbols do not start with the same letter as the English name of the element. For example, iron has the symbol Fe from its Latin name "ferrum".
  3. By convention, in chemical symbols, if it is a single - letter symbol, it is capitalized (e.g., H for hydrogen). If it is a two - letter symbol, the first letter is capitalized and the second is lowercase (e.g., Ca for calcium). So, the chemical symbol always begins with a capital letter.
  4. Each element has a unique chemical symbol and no two elements share the same symbol.

Answer:

The chemical symbol always begins with a capital letter.
