Number of protons PLUS number of valence electrons (plus - if needed - number of electrons in inner shell).
The number of protons in the element's nucleus
To organize the elements in Periodic Table, elements are arranged in order of increasing atomic number.
metal
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
The different elements are arranged in the increasing order of their atomic number and repeating chemical / physical properties.
The modern periodic table is based on the periodic law, which states that physical and chemical propertiesof the elements are a periodic function of their atomic numbers.Yes this answer is good!
In the modern periodic table, the elements are arranged in order of increasing atomic number.
by groups and periods
Atomic number is the fundamental property. Elements are arranged in order of increasing atomic number.
Henry Moseley founded modern periodic table. He proved that atomic number is the fundamental property to arrange the elements.
The Periodic Table has 118 elements and counting...
The modern Periodic Table arranges elements based on properties. These properties include valence electrons of the elements and density for example.

Periodic table of elements.
The elements are ordered by their mass number.
No. When the elements are arranged in order of increasing atomic number there is a periodic repetition of their physical and chemical properties.
The different elements are arranged in the increasing order of their atomic number and repeating chemical / physical properties.
112 elements are known, with the existence of addition 6 elements being tentatively proposed.
Mosley arranged elements in order of increasing atomic number
There are 117 elements on the periodic table, however, there is one blank spot that lies on the periodic table of elements, it has the atomic number of 117. If it were discovered, there would be 118 elements on the periodic table of elements.
