atomic number Chemical elements are organized in the form of the periodic table of Mendeleev, in groups and periods.
Periodic table show that elements have properties which are periodic in nature. These properties can be grouped together.
he drew up a table that grouped elements according to their atomic weights, his table became the basis for the periodic table of elements used today.
It is called the Periodic Table of Elements.
When it was discovered that Mendeleev's table was based on the wrong characteristic. He believed that it was the mass of the elements that affected their properties. It is, in fact, their atomic numbers
The modern periodic table is arranged according to the elements' atomic numbers.
the elements in the modern periodic table are arrange in the increasing order of their atomic numbers.
In the modern form of periodic table, all elements are arranged in increasing order of their atomic numbers. The periodic properties of elements are functions of their atomic weights.
The elements in the periodic table are arranged according to their atomic numbers, which are the numbers of protons in their atomic nuclei. The atomic number of hydrogen is 1 because it's atoms have one proton, which is why it's the first element in the periodic table.
Elements are organized in the periodic table by their atomic number, which represents the number of protons in the nucleus of an atom. The atomic number determines the unique properties of each element, and elements with similar properties are grouped together in columns called groups.
Periodic Table of elements.

The periodic table give the atomic numbers and the atomic weights of chemical elements.
The arrangement of all known elements in order of their atomic numbers is called the periodic table of elements. The periodic table organizes elements based on increasing atomic number, showing similarities in properties and periodic trends across rows and columns.
Atomic Number
The periodic table is just a way of grouping elements according to their atomic numbers. It helps scientists to understand why different elements react in different ways.
