it is the number of protons.the atomic number.
The periodic table of elements is the table that arranges different elements based on their common properties in rows and columns. It helps to organize and classify elements by their atomic number, electron configuration, and chemical properties.
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 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.
Both John Dalton's table and the modern periodic table contain elements like hydrogen, oxygen, carbon, and nitrogen that are essential building blocks of matter. However, Dalton's table had elements grouped by atomic weight, while the modern periodic table arranges elements by atomic number.
The periodic table of elements arranges all of the known chemical elements.
mass
Is the Periodic Table. The columns down are the GROUPS The lines across are the PERIODS.
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 is the table that arranges different elements based on their common properties in rows and columns. It helps to organize and classify elements by their atomic number, electron configuration, and chemical properties.
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
Because in the table the elements are arranged into "periods", elements belonging to the same period have similar physical/chemical properties. This in tern reflects the fact that they have a similar number of outer shell electrons.
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
The modern periodic table arranges elements based on their atomic number, which is the number of protons in the nucleus. Elements with similar chemical properties are grouped together in columns called groups or families. The table is divided into periods (rows) that indicate the number of electron shells in an atom.
