The element symbol

represents a chemical symbol of an element, called an element symbol.is usually represented by the first letter (capital) of the element's Latin name. For example, carbon (
Carbonium
) elements are
in
C. If the first letter of several element names is the same, add another letter in the element name (must be lowercase) after the first letter (must be capital) to show the difference. For example, the calcium

element is represented by
Ca
, and the
Cuprum
) element is represented by
Cu
.In , the Inorance Chemical Naming Committee of the International Union of Pure and Applied Chemistry
IUPAC
) adopted the Recommendation on the Naming of Elements with "Atomic Numbers Greater than
100
". It is not named as follows:(
1
) uses the following number of roots to determine the name of an element by its atomic number.0:1:un2:bi 3:tri 4:quad 5:pent 6:hex 7:sept 8:oct9:enn(
2
) connects the roots of the number of words in atomic order, plus the end of the word
ium
, the name of the element. For example, an element with an atomic number of
104
is named
Unnil-quadium
,


(
<1>3
) element symbol is represented by the first letter of the three roots in the representative number that make up the element name, such as the
104
element, which is
Unq
.An element symbol represents an element and can also represent an atom of such an element. In the thermochemical equation, the element symbol also indicates that the element's

1motom.Most solid-state monomorphisms are also commonly represented by element symbols.
