Atoms of elements with the same electron configuration are organized in in the Periodic Table?

They are not! It is a prevalent myth that the elements are organized so that elements with the same configuration are organized into the same group, but all that really matters is the number of valence electrons, and that much is guaranteed by the arrangement in order of atomic number.
So we have for example in group 10, Ni with configuration [Ar] 3d8 4s2 , Pd with configuration [Kr] 4d10 , and Pt with configuration [Xe] 4f14 5d9 6s1.
Group 4 is characterized (supposedly) by the electron configuration d2 s2 but thorium which has this configuration is not placed in this group but in the actinides.

Electron affinity tends to what?
Electron affinity is an elements' ability to attract electrons and is variable for each element. Generally the more electronegative atoms are furthest to the right bottom of the periodic table and ascending to the left the elements lose their electron accepting ability.
Elements are organized in the periodic table by their?
The periodic table is a function of the atomic number.
What does the periodic table list elements according to?
The elements are listed in ascending order, according to their atomic number. The periodic table is arranged in such a way that elements in the same column tend to have similar properties.
The elements in group 7A have one valence electron true or false?
A valence electron, or valence electrons, are found in all of the elements. A valence electron is an electron located on the out most shell of an element (the valence shell). Most elements will have more than one valence electron. Oxygen, or O, has six valence electrons because its outer shell consists of six electrons.
What tends to gain electrons?
Elements on the right of the periodic table but not in group 0/8 tend to gain electrons. Those in group 7 tend to gain 1 electron and those in group 6 tend to gain 2.
What is periodic table in chemistry?
The periodic table in chemistry is an arrangement that is in tabular form for all the chemical elements. The elements are organized based on their electron configuration, atomic numbers and so on.
Explain why the table of elements is periodic?
because of the electron configuration are different
How are elements catagorized in the periodic table?
The periodic table is organized in rows and colums called periods and groups. each period in the table helps correspond to the filling of a configuration of the outermost electron shells of their atoms.
Is there more than one periodic table?
No, there is only one periodic table. The periodic table is a tabular arrangement of chemical elements, organized based on their atomic number, electron configuration, and recurring chemical properties. It provides a systematic representation of the elements and is universally recognized and used in chemistry.
What column contains elements whose electron configuration end with d4?
what column of the periodic table contains elements whose electron configurations end with d4
Is the periodic table is most easily understood in terms of the electron configurations of the elements?
Yes. In terms of electron configuration and the number of valence electrons.
What is the relationship between the electron configuration of an element and the period in which that element appear in the periodic table?
Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
Why the scientist who made the first periodic table didn't understand why properties of elements repeated?
He didn't know about electron configuration.
What the correct electron configuration for chlorine?
The electron configuration for chlorine is 1s2 2s2 2p6 3s2 3p5.
The most useful source of chemical information about the elements is a?
periodic table. The periodic table provides a concise and organized overview of all the known elements, including their atomic number, atomic mass, and other key properties. It allows scientists to quickly access information about each element, such as its electron configuration, valence electrons, and chemical reactivity.
What is the document in which elements are organized by their properties called?
The Periodic Table of the Elements, sometimes called just the Periodic Table, is the document in which elements are organized by their properties. It was created in 1869.
How many electrons does group 7A need to become stable?
In the modern periodic table, these elements belong to group 17. These elements have s2 p5 electron configuration. Hence they need one more electron from an electron donor to fulfill its valence shell to obtain noble gas configuration.The elements in the group 7A has 7 electrons in their outermost energy level. They gain 1 electron to get the noble gas configuration. The elements in the group 7A are called halogens.
