In 1869, a Russian scientist named Dmitri Mendeleev arranged the elements in a table according to their Atomic Mass, this was the first Periodic Table. However, a few elements didn't fit the pattern in Mendeleev's table, so a new table had to be made, and that table is today's periodic table which is arranged by atomic number, and not atomic mass.
The properties of elements that follow a pattern that repeats every eight elements are known as the periodic properties. These properties include atomic radius, ionization energy, electron affinity, and electronegativity, which exhibit periodic trends across periods (rows) in the periodic table.
Groups are arranged as columns in the periodic table; the contained elements have similar properties.
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.
Yes, the properties of elements based on electron configurations are predictable and repeat in periodic patterns. This is known as the periodic law, where elements are arranged in the periodic table according to their increasing atomic number and similar chemical properties recur at regular intervals.
The Periodic Law states that when elements are arranged in order of increasing atomic number, their properties exhibit a periodic recurrence, with similar properties appearing at regular intervals. This lays the foundation for the organization of elements into periods and groups on the periodic table, based on their electron configurations and chemical behavior.

the periodic table.
The pattern of repeating properties of elements in the periodic table is called periodicity. This periodicity arises from the similar electronic structure and arrangements of elements within the table.
The properties of elements that follow a pattern that repeats every eight elements are known as the periodic properties. These properties include atomic radius, ionization energy, electron affinity, and electronegativity, which exhibit periodic trends across periods (rows) in the periodic table.

Periodicity, or periodic law.
The repeating pattern of elements and their properties in the periodic table is called periodicity. This refers to the predictable trends in properties such as atomic size, ionization energy, and electronegativity as you move across a period or down a group in the table.
Periodic trends refer to the repeating pattern of properties of elements as you move across a period or down a group on the periodic table. These trends can be recognized by observing how a particular property (such as atomic radius, electronegativity, or ionization energy) changes in a predictable way based on the element's position in the table. By comparing the properties of elements in a specific order, you can identify and analyze periodic trends.
Groups are arranged as columns in the periodic table; the contained elements have similar properties.
The periodic table is called "periodic" because it arranges elements in rows called periods based on their atomic number and chemical properties, showing a repeating pattern of properties.
