What is the modern periodic table arranged according to?

The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods.
A.

How is the periodic table of the elements arranged?

Periodic table of the elements, in chemistry, the organized array of all the chemical elements in order of increasing atomic number—i.e., the total number of protons in the atomic nucleus. Explanation of the periodic table.
B.

What scientists contributed to the periodic table?

  • Who modernized the periodic table of elements?

    Henry D. Hubbard was a member of the U.S. Bureau of Standards in the 1920s. He modernized Mendeleev's periodic table and in 1924 he produced a Periodic Table of Elements (called the Periodic Chart of the Atoms) which was distributed to schools and universities.
  • What is the atomic number of the element named after Mendeleev?

    Mendelevium is named after Dmitri Mendeleev. It is the ninth transuranium element of the actinide series discovered. It was first identified by Ghiorso, Harvey, Choppin, Thompson, and Seaborg in early in 1955 during the bombardment of the isotope 253Es with helium ions in the Berkeley 60-inch cyclotron.
C.

Who has given the modern periodic table?

The Russian chemist Dmitri Mendeleev was the first scientist to make a periodic table similar to the one used today. Mendeleev arranged the elements by atomic mass, corresponding to relative molar mass.
  • Who rearranged the periodic table?

    The periodic table was arranged by atomic mass, and this nearly always gives the same order as the atomic number. However, there were some exceptions (like iodine and tellurium, see above), which didn't work. Mendeleev had seen that they needed to be swapped around, but it was Moseley that finally determined why.
  • How are the elements in the modern periodic table are arranged?

    The modern periodic table is a chart containing the elements arranged in order of increasing atomic number. A vertical column, called a group, contains elements with similar properties. A horizontal row is called a period. Newlands and Mendeleev arranged the elements in order of increasing relative atomic mass.
  • How are the elements in the periodic table arranged?

    The chemical elements are arranged in order of increasing atomic number. The rows are called periods and the columns are called groups. Elements with similar chemical properties are in the same group of elements.
