Why is the periodic table periodic?
The periodic table is periodic because elements are arranged in order of increasing atomic number, which results in similar chemical properties repeating at regular intervals.
Which statement about the development of the periodic table is true?
The periodic table was developed by Dmitri Mendeleev in 1869. Mendeleev organized the elements by their atomic mass and observed that elements with similar properties occurred at regular intervals. This arrangement formed the basis for the modern periodic table.
In 1869 Mendeleyev found that the properties of the elements went through?
In 1869, Dmitri Mendeleev arranged the elements in a periodic table based on their atomic weights and noticed that the properties of the elements appeared at regular intervals. This led him to predict the properties of undiscovered elements and paved the way for the modern periodic table we use today.
Mendeleev was the first to arrange elements according to their properties in a?
periodic table. He organized the elements based on their atomic mass and observed that elements with similar properties appeared at regular intervals. This arrangement laid the foundation for the modern periodic table we use today.
Who arranged the elements into triads?
Dmitri Mendeleev arranged the elements into triads in the periodic table. Mendeleev noticed that elements with similar properties occurred at regular intervals when arranged by increasing atomic mass.
What does the word periodic means?
1. Having or marked by repeated cycles.2. Appearing or occurring at intervals.3. Relating to the Periodic Table of the elements or the pattern of chemical properties that underlies it.

Are the properties of elements that are based on electron configurations unpredictable and repeat in periodic patterns?
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.
What states that when elements are listed in order of atomic number similarities in their properties will emerge in a pattern?
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.

How the properties of element repeat after regular intervals?
The repetition of properties of elements after regular intervals is due to the periodic nature of the elements in the periodic table. This periodicity is a result of the elements having similar outer electron configurations within their respective groups or periods. The periodic table is organized based on increasing atomic number, which leads to the recurring patterns of properties such as atomic size, ionization energy, electronegativity, and chemical reactivity. This periodic trend is a fundamental aspect of the periodic table and is a key concept in understanding the behavior of elements.
Who arranged the elements into triads?
Dmitri Mendeleev arranged the elements into triads in the periodic table. Mendeleev noticed that elements with similar properties occurred at regular intervals when arranged by increasing atomic mass.
True or false mendeleev also grouped elements that has similar properties?
True. Mendeleev organized the elements into the periodic table based on their atomic weight and similar chemical properties. He noticed that elements with similar properties tended to occur at regular intervals, leading to the periodicity of the elements.
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.
Who created the periodic law?
that many of the physical and chemical properties of the elements tend to recur in a systematic manner with increasing atomic number.
