A Periodic Table should be helpful.
See related link below.
the atomic number, the atomic weight, the atomic symbol and atomic name.
One should use an appropriate periodic table or look up in wikipedia by typing the elements name correctly and scroll down the collumn at the right (looking for 'standard atomic weight' or just 'atomic weight').This is not exactly the same as the mass number.
It contains the symbols, atomic number, atomic name and the real name of the elements.
The atomic number.
The element symbol represents one mole of element , atomic number represents number of protons, atomic mass represents sum of protons and neutrons.
#79 is Gold (Au).
The periodic table provides information on the elements, including their atomic number, symbol, name, atomic mass, and electron configuration. It also categorizes elements into groups based on shared characteristics and properties.
Periodic table show that elements have properties which are periodic in nature. These properties can be grouped together.
The element with an atomic weight of 35.453 is chlorine (Cl).
Calcium has an atomic weight of 40. Other info about Calcium: Symbol: Ca Name: Calcium Atomic Number: 20 Atomic Weight: 40.08 Number of Neutrons: 20 (atomic weight - atomic number) Number of Protons: 20
Elements with atomic number 112 to 118
In 1913, almost fifty years after Mendeleev, Henry Moseley published the results of his measurements of the wavelengths of the X-ray spectral lines of a number of elements which showed that the ordering of the wavelengths of the X-ray emissions of the elements coincided with the ordering of the elements by atomic number. With the discovery of isotopes of the elements, it became apparent that atomic weight was not the significant player in the periodic law as Mendeleev, Meyers and others had proposed, but rather, the properties of the elements varied periodically with atomic number. When atoms were arranged according to increasing atomic number, the few problems with Mendeleev's periodic table had disappeared. Because of Moseley's work, the modern periodic table is based on the atomic numbers of the elements.
