In Dmitri Mendeleev's Periodic Table, elements were arranged in order of increasing Atomic Mass. Mendeleev noticed that when elements were organized this way, they exhibited periodic trends in their chemical properties. This arrangement allowed him to predict the existence and properties of undiscovered elements by leaving gaps in the table. His work laid the foundation for the modern periodic table, which is now organized by atomic number instead.
What else can I help you with?
Which two elements on the periodic tabel would have been placed in different groups in moseleys periodic table but not in mendeleevs?

What method did Dmitri used organize the elements?
According to Dmitri, properties of elements are periodic function of their atomic masses. He placed elements possessing same chemical properties together.
What was Dmitri medeleevs contribution to the periodic tale?
Mendeleev arranged the elements in order of increasing atomic mass.He placed the elements in rows and columns.
Why is iodine placed on the periodic table of elements?
The periodic table is an array of various elements. Iodine is an element. Hence it finds it place on the periodic table.
What is the section of elements that are placed outside of the periodic table called?
The elements that are placed outside of the periodic table are called transactinides. These elements are usually placed in a separate row below the main table and are synthetic elements that do not occur naturally on Earth.

When new elements are placed into the periodic table what happens?
If new elements are placed, then they would be appended in the periodic table. It won't disturb existing periodic table.
What method did mendeleev use to organize the element?
Dmitri Mendeleev organized the elements based on their atomic mass, grouping similar elements together and leaving gaps for undiscovered elements. This led to the creation of the periodic table, where elements with similar properties were placed in the same column.
Which elements in the periodic table are by the place?
Metals are placed at the left. Non-metals are placed at right in periodic table.
Elements in a periodic table in common?
The periodic table contain all chemical elements, placed in a rational order.
What is the name for the elements that have been removed from period 7 and instead placed below the periodic table?
The elements that have been removed from period 7 and placed below the periodic table are called the "lanthanides" and "actinides". These elements are also known as the "rare earth elements" and they are placed separately to conserve space on the periodic table.
Why does Thorium belong on the periodic table?
All chemical elements are placed in the periodic table.
