It is about the atomic number. the number of protons.
Mendeleev organized the periodic table based on increasing atomic mass and grouped elements with similar chemical properties into columns. He left gaps for undiscovered elements, predicting their properties. Moseley later refined the table by arranging elements according to increasing atomic number, which resolved inconsistencies in Mendeleev's arrangement and established the modern periodic law that elements exhibit periodic properties when ordered by atomic number.
Henry Moseley
Mendeleev's version of the Periodic Table was organized by increasing mass. The modern periodic table is now organized by atomic number.
He found the number of protons an element has. present periodic table is according to it.
Moseley's periodic table was developed by English physicist Henry Moseley in 1913. He rearranged the elements on the periodic table based on their atomic number rather than atomic mass, which led to the modern form of the periodic table. Moseley's work provided a clearer understanding of the organization of elements and their properties.
Henry Moseley created current Periodic Table. Elements were arranged in order of atomic number.
The Periodic Table of Elements was modified by the English scientist Henry Moseley in the year 1913. Moseley assessed the atomic number of the elements individually and organized the atoms according to increasing atomic number.
Mendeleev organized the periodic table based on increasing atomic mass and grouped elements with similar chemical properties into columns. He left gaps for undiscovered elements, predicting their properties. Moseley later refined the table by arranging elements according to increasing atomic number, which resolved inconsistencies in Mendeleev's arrangement and established the modern periodic law that elements exhibit periodic properties when ordered by atomic number.
The periodic table after Moseley is logical and without physical anomalies.
Arranging the Periodic Table by atomic number rather than Atomic Mass was first suggested by a British man named Henry Moseley in 1913. Before that point, the periodic table was organized by atomic mass, and has several inconsistencies and problems.

Mendeleev's version of the Periodic Table was organized by increasing mass. The modern periodic table is now organized by atomic number.
He is called the "Father of the periodic table" because he organized the elements according to increasing atomic mass.
He found the number of protons an element has. present periodic table is according to it.
