Periodic means repeating.
When Mendeleev was rearranging the elements, he noticed that some of their properties matched with one another about every eight elements. Thus, when the elements are arranged in the rows of the Periodic Table, they also have matching properties in each column.
The periodic table is a method of listing elements which groups elements with similar properties together. It was noticed that if the elements were listed in order of Atomic Mass there was a distinctive pattern of characteristics that repeated itself every 8 elements. There were slight imperfections due to the fact that it was not the atomic mass but the nuclear charge that determined the properties (the nuclear charge could not be measured directly but was related closely to the atomic mass)
The modern periodic table was formed by Dmitri Mendeleev. He even left gaps which he (correctly) predicted would be filled by elements not yet discovered.
The word "periodic" means recurring in a predictable pattern. It's the same as a magazine that is published bi-weekly being called a "periodical;" or a woman's menstrual "period," which comes about once a month. On the periodic table, certain properties of elements recur, and if the elements are arranged a certain way, these recurring properties can be organized in a meaningful way that makes predictability and generalizations possible.
periodic means time for chuncks of time. It means that in the periodic table the elements are organized by when they were found, the mass number, the abreviation, the state of matter, etc.
The periodic table is made up of 7 periods, which are horizontal rows and correspond to the highest energy level orbital that an element naturally possesses.

Periodic means repeating in some form. The periodic table of the elements are periodic because all the elements in the column have similar properties.

How did the periodic table get its name?
Based on the periodicity of the elements regarding properties, reactivity, valence electrons, etc.
What is Periodicity best defined as in chemistry?
Periodicity in chemistry refers to the repeating patterns of properties of elements on the periodic table based on their atomic number. This periodic trend helps in predicting the physical and chemical properties of elements and their compounds. The concept is essential for understanding the behavior of elements and the organization of the periodic table.
Is periodicity defined as the fact that elements increase in atomic mass in a regular way?
No, periodicity refers to the recurring trends in properties of elements as one moves across and down the periodic table. These trends are a result of the arrangement of electrons and the periodic table's structure. Atomic mass is not the primary factor in determining periodicity, although elements do follow a general increasing trend in atomic mass as one moves across a period.
What is the contribution of Dechancourtois to periodic table?
Dechancourtois is credited with the first published version of the periodic table in 1862, where he arranged the elements in a spiral format based on atomic weights. His work laid the foundation for the modern periodic table by demonstrating the periodicity of elements.
Who showed that periodicity depended upon atomic number?
Henry Moseley showed that periodicity depended upon atomic number. He rearranged the periodic table based on atomic number rather than atomic mass, providing a more accurate representation of the periodic trends.
What did mendeleev mean by periodicity of properties?
what he meant by it was it meant the same as periodic table.
What is the periodic table according to?
This is the law of periodicity.
What is the pattern in repeating the properties of elements in the periodic table known as?
Periodicity, or periodic law.
What is an example of periodicity?
A good example of periodicity would be the size of an atom which decreases across the Periodic Table but increases down the column
What does periodicity means on the periodic table?
Periodicity on the periodic table refers to the repeating pattern of physical and chemical properties of elements as you move across or down the table. This periodic pattern is a result of the elements having similar outer electron configurations within the same group or period. Periodicity helps to predict an element's properties based on its position in the periodic table.
The pattern of repeating properties of elements revealed in the periodic table is known as what?
Periodicity, or periodic law.
What organization governs the periodic table?
This is the law of chemical properties periodicity.
What are the different features of periodic table?
- the periodic table is organized in periods and groups- chemical elements are listed in the order of the atomic number- the periodic table obey the law of periodicity
What is pattern of repeating properties of elements revealed in the periodic table called?
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.
How did the periodic table get its name?
Based on the periodicity of the elements regarding properties, reactivity, valence electrons, etc.
How do the atomic numbers of the elements with in each of group 1 2 and 13-18 of the periodic table vary?
Mendeleev's Periodic Table -- the reason for periodicity -- is explained by the arrangement of the electrons around the nucleus. *Read your chemistry book* :D
What are Dmitri Mendeleev's discoveries except the periodic table are?
Periodic Principles Law of Periodicity Periodic Table of Toxic Elements These are three of the many discoveries Dmitri Mendeleev researched during his life (1834-1907).
