17 maj 2014 · Here is a list of elements of the periodic table, their atomic numbers, and element symbols. The list is ordered by increasing atomic number, which is the number of protons in an atom of that element. Each element has a symbol, which is a one- or two-letter abbreviation of its name.
Atomic number: The number of protons in an atom. Each element is uniquely defined by its atomic number. Atomic mass: The mass of an atom is primarily determined by the number of protons and neutrons in its nucleus.
PeriodA horizontal row in the periodic table. The atomic number of each element increases by one, reading from left to right. BlockElements are organised into blocks by the orbital type in which the outer electrons are found.
