Atomic Mass Example
This is a list of chemical elements, sorted by atomic mass (or most stable isotope) and color coded according to type of element.Each element's atomic number, name, element symbol, and group and period numbers on the periodic table are given. The number in parenthesis gives the uncertainty in the 'concise notation' dis given in parenthesis next to the least significant digits to which it. Tungsten (W) is a steel-gray coloured metal that has the atomic number 74 in the periodic table. It is a Transition metal in Group 6. It has the symbol W. Tungsten is named from the Swedish name for the mineral, tungstate which it is found in ‘scheelite' which means heavy stone. It is a rare metal found in minerals such as wolframite. Compiled by Bob Sharpe and MacHenry Gilmour. Tungsten is a metallic element with an Atomic Number 74, and Atomic Symbol. Tungsten has the highest melting point of all metals (3422 C), one of the highest densities and, when combined with carbon, is almost as hard as diamond.

In the modern periodic table, the elements are listed in order of increasing atomic number. The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present). The number of protons determines how many electrons surround the nucleus, and it is the arrangement of these electrons that determines most of the chemical behavior of an element.
Atomic Number 74
In a periodic table arranged in order of increasing atomic number, elements having similar chemical properties naturally line up in the same column (group). For instance, all of the elements in Group 1A are relatively soft metals, react violently with water, and form 1+ charges; all of the elements in Group 8A are unreactive, monatomic gases at room temperature, etc. In other words, there is a periodic repetition of the properties of the chemical elements with increasing mass.
Tungsten Element Number
In the original periodic table published by Dimitri Mendeleev in 1869, the elements were arranged according to increasing atomic mass— at that time, the nucleus had not yet been discovered, and there was no understanding at all of the interior structure of the atom, so atomic mass was the only guide to use. Once the structure of the nucleus was understood, it became clear that it was the atomic number that governed the properties of the elements.
