What else can I help you with?
What statement says that the properties of elements repeat in predictable way when atomic numbers are used to arrange elements into groups?
This is called the "Periodic Law" or "Principle of Periodicity".
Why is the periodic tables called the periodic table?
It is arranged such that similar elements with similar preferred bonding arrangements are aligned vertically. This exposes the various s, p, d, and f bonding orbitals for each successive "exterior" shell, and so appears to repeat... hence "periodic".
What evidence would have refuted Mendeleev's predictions?
A clear refutation of Mendeleev's predictions would have been discovering elements that did not fit into his periodic table based on atomic weight and properties. If the properties of elements did not repeat in a periodic manner when arranged by atomic weight, this would have refuted his periodic law.
In what way is the table of the elements periodic?
The Periodic Table is arranged in periods and groups; elements are placed in the ascending order of the atomic number. The law of periodicity from Mendeleev is respected.
Why do suppose that the word periodic is used to describe the periodic table?
Because the table repeats itself according to similar chemical properties (i.e. those elements with 5 valence electrons all behave similarly to each other, thus they are in the same column), the properties of the elements periodically repeat themselves as the number of valence electrons (those in the s and p shells) reach 8 and a new valence shell begins.
What statement says that the properties of elements repeat in predictable way when atomic numbers are used to arrange elements into groups?
This is called the "Periodic Law" or "Principle of Periodicity".
What is the main idea in the periodic law?
The main idea of the periodic law is that the properties of elements repeat in a periodic manner when arranged by increasing atomic number. This periodicity helps predict the physical and chemical properties of elements based on their position in the periodic table.
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 are the properties of elements that tend to repeat in a regular pattern when elements arranged in order of increasing atomic mass?
The properties of elements that tend to repeat in a regular pattern when arranged by increasing atomic mass are known as periodic properties. These include atomic radius, ionization energy, electronegativity, and electron affinity. Such periodicity arises from the recurring arrangement of electrons in the outer shells of atoms, leading to similarities in chemical behavior and reactivity among groups of elements. This pattern is the foundation of the periodic law and is visually represented in the periodic table.
What did Mendeleev conclude when constructing the periodic table?
Dmitri Mendeleev concluded that when elements are arranged in order of increasing atomic mass, their properties repeat periodically. He left gaps for undiscovered elements and predicted the properties of these missing elements based on their neighboring elements. This led to the development of the modern periodic table.

When mendeleev made his arrangement of the elements in a table he found that elements with fell into groups on the table.?
Yes, Mendeleev noticed that elements with similar properties tended to repeat at regular intervals when arranged by atomic mass, forming groups or columns in his periodic table. This led him to predict the properties of undiscovered elements and leave gaps in the table for them.
What law states that properties of elements repeat as a function of their atomic number?
Mosley's periodic law
What is the periodic law?
Periodic Table of elements.
In what way is the table of the elements periodic?
The Periodic Table is arranged in periods and groups; elements are placed in the ascending order of the atomic number. The law of periodicity from Mendeleev is respected.
Why is the table of elements known as the periodic table?
It is called the periodic table because the elements are arranged in order of increasing atomic number, showing periodic trends in their physical and chemical properties. These patterns repeat at regular intervals, or periods, across the table.
