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?
14 of them.
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.
Why is the symbol for bromine BR on the periodic table?
While giving symbols to the elements the first letter of the name of the element was used. But in case of two or more elements with same initial the next elements were given symbols containing first two letters. Since boron has symbol B, so bromine got the symbol Br.
Why are there 3 lettered elements?
There are a few chemical elements with three-letter symbols. Some examples include: Tin (Sn) Barium (Ba) Xenon (Xe) Argon (Ar) Radon (Rn) These elements are often represented by their chemical symbols, which are typically one or two letters.
How many different elements are in C5H12?

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 elements have two letters in their symbol?
99 elements have been identified and named and given 2 letter symbols. 13 elements have 1 letter symbols. Additional elements have been theorized, but not synthesized or named, and have 3 letter symbols. See Wikipedia Periodic Tables, linked.
How many elements have 1 letter symbols?
14 of them.
What is Si Br?
Symbols for two chemical elements. It is certainly not a stable compound of the two.
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 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.
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.
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.
Symbols for elements in dinitrogen oxide?
N2O there are two nitrogens and one oxygen
Where do the symbols of elements derived?
Symbols of chemical elements are derived from the chemical name.
