Isotopes and their prevalence are not shown on the periodic table. Instead, the atomic weight shown for each element is an average of the atomic weights of all naturally-occurring isotopes (calculated from percentages occurring on Earth).

What can you not find on the periodic table?
Isotopes of each element.
What is the abbreviation for potassium in the periodic table?
The abbreviation for potassium is " K " in the periodic table. It is placed in group-1 of the periodic table.
Were are the lanthanides placed on the periodic table?
After lanthanum, thus the name.
Where are the lanthanides placed in the periodic table?
Lanthanides are placed in a special row under the classical periodic table; but this arrangement is only a convention.
Is there any acid or alkalis on the periodic table?
Acids are not on the periodic table. Acids are compounds, the periodic table is only for elements.
Where are the isotopes of the same elements having different atomic masses placed in the periodic table?
same slot
Why do individual isotopes not appear on the periodic table?
In the periodic table only the chemical elements appear; but tables for isotopes also exist.
Are most of the periodic table isotopes?
No most of them are not isotopes. Few elements exist as isotopes.
What group is astatine in the periodic table?
Astatine is placed in group-17 in the Periodic Table. Its symbol is At.
WHAT IS FE2O3 IN PERIODIC TABLE?
Compounds are not placed in the periodic table.
Where are there actnoides placed on the periodic table?
Actinoids are placed in a separate row under the periodic table.
What can you not find on the periodic table?
Isotopes of each element.
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.
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 do radioactive atoms start on the periodic table?
After lead, all elements on the periodic table have only radioactive isotopes.
What is the position of isotopes in the modern periodic table?
Isotopes are atoms of same element having different atomic mass, but the same atomic number. Isotopes have not been given separate place in the modern periodic table.
What group is co3 in the periodic table?
CO3 is not placed in periodic table. Only elements are arranged in periodic table.
