Not always... There are chemical elements beginning with the same letter - for example Copper and Cobalt. However - every chemical symbol does consist of two letters.

What are the ways of writing of the symbols of elements in the periodic table?
The chemical symbols are approved by IUPAC; symbols are derived from the name of the chemical element in Latin, frequently the first two letters.
What elements have their first two letters as a symbol?
The symbols for elements have either one or two letters. If there are two letters, the first one is capitalized and the second one is not.
Do elements have capitals letters?
In the periodic table, elements' names are written with a capital letter for the first letter only, like Oxygen (O) or Gold (Au). When chemical symbols are used, those symbols are capitalized.
What are the letters on periodic table called?
The letters on the periodic table represent the chemical symbols for each element. These symbols are typically derived from the elements' names in Latin, Greek, or other languages. Each chemical symbol consists of one or two letters, with the first letter often capitalized and the second letter, if present, in lowercase.
Why do some element have unusual letter for their symbols?
some elements do not use their first letters of their English names as their symbols. The symbols for these elements may come from the names of the elements in a different language.
How are chemical symbols of elements formed?
Chemical symbols of elements are formed by using one or two letters derived from the element's name in English or Latin. For example, the symbol for oxygen is "O," derived from its name. In some cases, the first letter of the element's name is used, while in others, the first and another letter are combined.
Why some symbols- for example cal and si- have two letters?
These symbols for chemical elements are derived from their names in Latin. "Cal" represents calcium and "Si" represents silicon. The symbols are typically chosen based on the first one or two letters of the element's name in Latin.
Of the first 103 elements how many have two letters in their symbols?
Not all elements can be identified by a single letter. For example, Carbon (C) and Chlorine (Cl) both start with a "C" and have "C"'s in their symbols. Another letter had to be added to distinguish the two. Also, the Periodic Table has over 100 elements and there would not be enough letters to cover them all if they were only single letters.
What do chemists use to represent elements and compounds?
Scientists use symbols to represent elements and compounds. The symbols of a chemical element are abbreviations that are used to denote a chemical element. Typically, they are one or two-letters long with the first letter (only) capitalised; temporary names are three-letters long. !
How do you write chemical symbols of compound?
Chemical symbols for compounds are written by combining the chemical symbols of the elements in the compound, along with subscripts to indicate the number of atoms of each element present. For example, water (H2O) is composed of two hydrogen atoms and one oxygen atom. The chemical symbols are always listed with the element that appears first in the compound listed first.
What are the chemical symbols on the periodic table?
It's easier to navigate the periodic table and write chemical equations and formulae once you know the symbols for the elements. However, sometimes it's easy to confuse symbols of elements with similar names. Other elements have symbols that don't seem to relate to their names at all! For these elements, the symbol usually refers to an older element name that isn't used any more. Here's an alphabetical list of element symbols with the corresponding element name. Keep in mind that the names for the elements (and their symbols) may be different in languages other than English.
What are the rules for chemical symbles?
Chemical symbols are typically one or two letters long, representing the elements in the periodic table. The first letter is always capitalized, and if there is a second letter, it is always lowercase. Elements can also be represented by their full name.
