Which two elements on the periodic tabel would have been placed in different groups in moseleys periodic table but not in mendeleevs?
bi and po
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.

How modern periodic law removed the defects of mendeleevs system of classification?
The properties of elements are the periodic function of their atomic numbers. REMOVAL OF DEFECTS OF MENDELEEV'S PERIODIC TABLE periodic table obtained on the basis of increasing atomic numbers has removed defects of Mendeleev's periodic table . 1) POSITION OF ISOTOPES : since the isotopes of the same elements have the same atomic number, they are given the same place in the table. 2) POSITION OF RARE EARTHS: These elements are separately placed at the bottom of table . similarly Acton elements ( which were discovered after Mendeleev ) are also placed at the bottom of the periodic table. 3) ANOMALOUS PAIRS. the arrangement according to the atomic number show that their placements are correct.
Where are landthanides and actinides actinides placed in the periodic table?
Lanthanides and Actinides are placed separately as the properties of these elements is quite different from the elements in periodic table.
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.
Why is iodine placed on the periodic table of elements?

Why does Thorium belong on the periodic table?
All chemical elements are placed in 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.
