Henry G. J. Moseley
Dmitri Mendeleev is credited with arranging the elements in the periodic table according to increasing weight. He also left gaps for undiscovered elements and predicted their properties, leading to the development of the modern periodic table.
A period on the periodic table is a horizontal row of elements that share similar properties. It helps organize the elements by arranging them in order of increasing atomic number and grouping elements with similar chemical properties together.
Mendeleev developed the periodic table of elements by arranging the elements in order of increasing atomic mass in 1869. He discovered that elements with similar properties occurred in a periodic pattern. He was able to predict the properties of elements that were missing at the time because of this pattern. In 1914, Moseley contributed to the periodic table by reorganizing the elements according to 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.
Dmitri Mendeleev is credited with creating the periodic table, a method for arranging elements based on their properties and atomic number. This arrangement allows for predicting the properties of elements that had not yet been discovered at the time.
Many attempts were made by Dobereiner , Newlands and Mendeleev in initial stages. Later on , the idea of arranging elements in increasing atomic number came up which is the today's periodic table.
The periodic table is designed based on the atomic number (number of protons in the nucleus) and the electron configuration of the elements. Elements are arranged in rows and columns based on their similarities in properties. This organization helps predict the behavior and properties of elements.
Actually, Dmitri Mendeleev formulated the periodic law and published his periodic table of elements in 1869. This table arranged elements by increasing atomic mass and grouped them based on similar properties, predicting the properties of missing elements. It was a significant contribution to the field of chemistry.
Elements in the periodic table are arranged based on their atomic number, which represents the number of protons in the nucleus of an atom. This arrangement helps to group elements with similar properties together in periods and groups.
Dmitri Mendeleev came up with the system for arranging the elements so he is also given credit for the modern periodic table. He arranged them based on each elements increasing atomic weight.
