a molecule or compound. Each element is represented by its chemical symbol (e.g. H for hydrogen), and the number of atoms of each element is denoted by a subscript following the symbol (e.g. H2O for water).
The upper left number in the symbol of an element on the periodic table represents the atomic number. This number indicates the number of protons found in the nucleus of the atom. Each element has a unique atomic number, which helps to identify and differentiate it from other elements.
The sign or abbreviation to represent an element is called an "atomic symbol", and there is a distinct one for each element. Every atomic symbol begins with a capital letter, which may constitute the entire symbol but is usually followed by a lower case letter.
E is related to a group of elements in chemistry by being the symbol used to represent an element in the periodic table. Each element is uniquely identified by its atomic number and symbol, with E being a placeholder for a specific element's symbol.

The number below the symbol in the periodic table of elements is the relative atomic mass. It is calculated by taking the mass of all of the ions of an element and working out the mass based on the percentage occurrence of each ion.
One or two letters are used to represent the name of each element.
The upper left number in the symbol of an element on the periodic table represents the atomic number. This number indicates the number of protons found in the nucleus of the atom. Each element has a unique atomic number, which helps to identify and differentiate it from other elements.
The beads each represent one completed year at camp. They are always painted with a symbol that represent a major event from that year.
The symbol for national capitals is usually a star enclosed in a circle. Other cities are represented by different symbols, which often represent an approximate population number. Maps almost always have a key that tell you what each symbol means.

Addition, subtraction and division, respectively.
Symbols are the short forms to represent elements. Each element will have a unique symbol.
They are the symbols for the elements . Often they are some of the letters of the English name.For example, Si means Silicon. Silver cannot be Si as well. Therefore, we use the Latin translation, Argentium, to create Ag.
