it is the number of protons.the atomic number.
The composition of the periodic table is made up of periods and groups. The table arranges the chemical elements based off of their atomic numbers, chemical properties and electron configurations.
The elements of the periodic table are arranged in groups and periods. All of the elements in a period have the same number of atomic orbitals where as in a group all the elements have the same number of valence electrons.
There are 118 elements. They are on the Periodic Table.
In the modern version of the periodic table, the elements are arranged in increasing order of the atomic number. The chemical properties of an element can be predicted by its group. For example group 1 elements react violently to give away one electron to form +1 ions where group 18 elements are inert in standard temperature and pressure. This periodic table was introduced by Henry Mosley.
The periodic table of elements arranges all of the known chemical elements.
mass
That's the Periodic Table of the Elements.
it is the number of protons.the atomic number.
The modern Periodic Table arranges elements based on properties. These properties include valence electrons of the elements and density for example.
The Periodic Table of Elements can be found in most introductory chemistry and science books. It can also be found on a variety of online sources. It arranges the chemical elements by different groups.
The atomic number is what arranges the elements (1,2,3,4........). It also tells the number of protons
The composition of the periodic table is made up of periods and groups. The table arranges the chemical elements based off of their atomic numbers, chemical properties and electron configurations.
It arranges all known elements in a chart of rows and colums of increasing atomic number.
The periodic table arranges elements not only by their atomic numbers, but by properties called periodic trends. These include, electron affinity, ionization energy, metallic and nonmetallic character, and atomic radius. http://en.wikipedia.org/wiki/Periodic_trends
