Every element recognized so far has a unique symbol in the Periodic Table. Some has one letter in their symbol, where many have two letters. A set of recently discovered elements using nuclear fission reactions have three.
What else can I help you with?
Why do some symbols have one letter some have two letters and some have three letters?
Elements are give symbols consisting of letters, and these are related to the names of the elements (in some language at some date). There are 26 letters in many alphabets, but more than four times that number of elements. So it is necessary to use some mechanism to distinguish among elements with names that start with the same letter. Adding numbers is done to designate the number of atoms in a compound, the isotope, and so on. The best solutions is to use pairs of letters for most elements.
How many different elements are in C5H12?
Two, as indicated by the presence of only two distinct atomic symbols in the formula.
How many elements have 1 letter symbols?
There are 3 elements with 1-letter symbols in the periodic table: Hydrogen (H), Helium (He), and Uranium (U).
What of these statements is true of chemical symbols?
Chemical symbols are representative abbreviations for the names of elements. They are typically one or two letters long and are used to identify elements in the periodic table and chemical formulas.
What element are one or two letter abbeviations for the names of the elements?
All elements that don't currently have IUPAC systematic placeholder names have one or two letter chemical symbols. So, currently, elements 1 (Hydrogen) to 112 (Copernicium) have one or two letter symbols.
How many elements are listed on the periodic table that has symbols for them?
All the elements listed on periodic table has symbols for them.There are total 118 elements in periodic table.

How many letter symbols can an element have?
Most elements have either 1 or 2 letters but some elements such as Ununpentium, have 3 (Uup)
How is using symbols how can you distinguish between two different element if both start with the same letter?
Many chemical elements have a two letter symbol.
What is Si Br?
Symbols for two chemical elements. It is certainly not a stable compound of the two.
How many different elements are in C5H12?
Two, as indicated by the presence of only two distinct atomic symbols in the formula.
Why do some elements have a number and some have symbols?
A way to know what this means is to know that the reason being is because it is a Isotope. An istotope is something that has too many nuetrons or more than one nuetron. So that is what they call it...
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.
How many elements have 1 letter symbols?
There are 3 elements with 1-letter symbols in the periodic table: Hydrogen (H), Helium (He), and Uranium (U).
Where do the symbols of elements derived?
Symbols of chemical elements are derived from the chemical name.
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.
Why are there so many atomic symbols?
Because there's lots of elements.
