Besides the periodic table, an electron chart of the elements exists. The periodic table shows the broad outline. The electron chart goes into greater detail. The periodic table lists elements according to electrons in their outer shell. As elements get more massive they get more protons and electrons. Each time they add a proton, they jump one notch in the periodic table. When they add the electron, it is a valence electron and it affects the chemical properties. There comes a point when elements start adding electrons when the electrons are not added to the outer shell with the other electrons in the valence shell. The chemical properties do not change as the elements get heavier. It is extremely difficult to use chemistry to separate the elements in that group. If you had an electron chart, you would see the electrons followed a different pattern. That is why the lanthanides and actinides are set apart from the other elements on the periodic table. According to their chemical properties, they would all need to be put into one box.
Lanthanides and actinides are actually part of the Periodic Table, occupying the two rows at the bottom known as the f-block elements. They are often separated out and placed below the main portion of the table to avoid making it too wide and unwieldy. This positioning helps maintain the periodic table's organizational structure while highlighting the unique properties of these elements.
it is because the lanthinides and actinides have there prepenultimate shell complete to acquire stability as they are stable by completing there pre-- penultimate shell ,,,they gain stability...As far as other elements are conCERND completion of their penultimate or ultimate shell,,gives them stability so they are outside the table
penultimate shell --- shell inner to valence or outermost or ultimate shell
ultimate shell--outermost shell
Partly for convenience, since a "super-wide" form periodic table would be too wide to fit on a single normal page. This is also justified chemically, because all of these elements have chemical properties very similar to each other and to other elements in column 3. Why_are_the_lanthanides_and_actinides_placed_below_the_periodic_table
They are not actually detached. They are only put at the bottom to condense the periodic table more reasonably. If you look at a picture of the extended periodic table you would see that they are right in there with the transition metals
To avoid having to print the table on even wider paper, thus turning it into the "Periodic Banner of the Elements".
Lanthanide and actinide are not individual elements they refer to a series or group of several elements which are on the periodic table

Is thorium belonged to f block elements?
No, thorium is not part of the f-block elements. It is classified as an actinide element, and it belongs to the actinide series of the periodic table.
What is einsteinium normal phase?
Einsteinium is a synthetic element and its normal phase is solid at room temperature. It is a radioactive metal with a silvery color and is part of the actinide series on the periodic table.
The group number and name where you will find sodium on the periodic table?
Sodium can be found in group 1 and it is listed in the periodic table as part of the alkali metal group.
What is unique about element 89-112?
Elements 89-112, known as the actinide series, are part of the f-block in the periodic table. They have unique electron configurations due to the filling of the 5f orbitals. These elements also exhibit a variety of oxidation states and have applications in nuclear energy and research.
What group does ununtrium belong to?
Ununtrium belongs to the group of elements known as the transactinides. These elements are part of the periodic table's seventh period and are characterized by their high atomic numbers and unstable radioactive properties.
What is Metallic element beginning With you?
Uranium (part of the actinide series of the periodic table)
Is Nobelium a metal?
Yes, Nobelium is a synthetic radioactive metal. It is part of the actinide series on the periodic table.
What is the eighty ninth element in the periodic table of the elements?
The eighty ninth element in the periodic table is Actinium, with the symbol Ac and atomic number 89. It is a radioactive element that is part of the actinide series.
Is berkelium a metal or a non metal?
Berkelium is a metal. It is a transuranium element and is part of the actinide series on the periodic table.
Is thorium belonged to f block elements?
No, thorium is not part of the f-block elements. It is classified as an actinide element, and it belongs to the actinide series of the periodic table.
What does Db on the periodic table of elements stand for?
Db on the periodic table stands for Dubnium. It is a synthetic element with the atomic number 105 and is part of the actinide series. Dubnium is highly radioactive and is produced artificially in laboratory settings.
Which element has the chemical symbol Cm?
The element with the chemical symbol Cm is curium. It is a radioactive metal and is part of the actinide series on the periodic table.
Which element family is usually shown separated frome the main part of the periodic table?
The lanthanide and actinide element families are typically shown below the main part of the periodic table to help conserve space. They are also known as the "f-block" elements.
What row does the actinides series occupy?
The actinide series is part of the seventh row of the periodic table, which is probably the highest row that contains elements stable enough to be identified.
Which element family is usually shown separated from the main part of the periodic table?
The lanthanide and actinide series are typically shown below the main part of the periodic table, known as the "f-block." These elements are often separated to keep the table compact, as they are very similar in properties and would make the table much wider if included in the main body.
Element named after albert einstien?
Einsteinium is the element named after Albert Einstein. It is a synthetic element with the atomic number 99 and is part of the actinide series on the periodic table.
Is carbon a family name or a rare earth element series?
Carbon is not a family name; it is a chemical element that is found in group 14 of the periodic table. It is not part of the rare earth elements series, which are a group of 17 elements in the lanthanide series and actinide series of the periodic table.
