Number of protons PLUS number of valence electrons (plus - if needed - number of electrons in inner shell).
Atomic number on the basis of Modern periodic law as on the view of Henry Mosely
The modern periodic table contains approximately 118 elements.
The modern periodic table was created by Dmitri Mendeleev in 1869. He arranged the elements based on increasing atomic mass and similar chemical properties. Mendeleev's table provided a framework for organizing the known elements and predicting the properties of undiscovered elements.
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!
The modern periodic table is based on the atomic number of elements, which is the number of protons in the nucleus of an atom. Elements are arranged in order of increasing atomic number, which helps to group elements with similar properties in columns called groups or families.
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 contains approximately 118 elements.
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.
British scientist Henry Moseley determined the concept of atomic number as the basis for the modern periodic table, demonstrating that it is a more fundamental property of an element than its atomic mass. He also used X-ray spectroscopy to accurately determine the atomic numbers of elements, which led to a more organized and predictive arrangement of the elements in the periodic table.
The elements are ordered by their mass number.
112 elements are known, with the existence of addition 6 elements being tentatively proposed.
