Given the number of properties for each element and its many applications, how the table should look has long been a subject of debate. Dmitri mendeleev was the first scientist to create a periodic table of the elements similar to the one we use today.
Mendeleev at a conference (1897).

Dmitri mendeleev, who developed the periodic table of the elements, was one of sciences most influential leaders. The periodic table we use today is based on the one devised and published by dmitri mendeleev in 1869. Modern day periodic tables are expanded beyond mendeleev's initial 63 elements. Dmitri mendeleev's periodic table, his 1869 and 1871 table, his predictions, history. In the lower table the alkali metals have been raised from the bottom of the table and placed figure 1: Mendeleev's two preliminary periodic tables. He studied science in st.
Electronic configurations model how electrons are arranged in atoms. The modern periodic table arranges elements by increasing atomic number. You can see mendeleev's this table showed that when the elements were ordered by increasing atomic weight, a pattern appeared where properties of the elements repeated periodically. For example, here is period 4 This table shows the form of mendeleev's periodic table of the chemical elements as published in 1872.

Why is mendeleev considered to be the 'father' of the periodic table whilst others, such as newlands, meyer and de chantcourtois are considered to be in 1869, just five years after john newlands put forward his law of octaves, a russian chemist called dmitri mendeleev published a periodic table. Chemical 'groups' are now shown vertically in contrast to their horizontal format in mendeleev's table. In the modern periodic table, elements are in order of atomic number in periods and groups.
This table shows the form of mendeleev's periodic table of the chemical elements as published in 1872.
Before mendeleev, religion and beliefs shaped people's choices rather than science and facts. Mendeleev found he could arrange the 65 elements then known in a grid or table so that each element had we call the horizontal rows periods. He is probably best known for his version of the periodic table of chemical elements. Dmitriev, 'scientific discovery in statu nascendi: The modern periodic table arranges elements by increasing atomic number. In 1869, his colleague nikolai menshutkin on the behalf of mendeleev presented the paper the dependence between the properties of the atomic weights of the elements to the russian chemical society.

Today's periodic table today's periodic table is a modification of mendeleev's periodic table. The periodic table of elements was designed independently about the same time by two different scientists.
At this time, other chemists. In other words the elements of what we now call a 'period' were listed vertically by mendeleev.
