The positions of isotopes in the modern Periodic Table are not explicitly shown; instead, elements are represented as whole entities, with isotopes being variations of these elements based on their neutron count. The periodic table is organized by atomic number, which corresponds to the number of protons in an element's nucleus. Isotopes of an element share the same atomic number but have different atomic masses due to varying numbers of neutrons. The average Atomic Mass listed on the table reflects the weighted average of all naturally occurring isotopes of an element.
Isotopes are not specifically located in the modern periodic table because they have the same number of protons (same element) but different numbers of neutrons. However, isotopes of an element share similar chemical properties due to their identical electronic configurations.
The periodic table would be disturbed only if isotopes of a new element are discovered, because a periodic table is based on order of atomic number, not atomic mass. If new isotopes of a previously known element were discovered, the atomic mass shown in the periodic table might be changed, but this is very unlikely because the atomic masses shown in a periodic table are based on the naturally occurring distribution of isotopes, and any newly discovered isotopes would probably occur only in very small fractions of the total.
1.) The atomic mass in Mendeleev's periodic table does not increase regularly. therefore, it was impossible to predict the number of elements between two elements.The Modern periodic table has been made according to the increasing atomic number (Modern Periodic Law states that 'The properties of an element are the periodic function of its atomic number). The atomic number gives us the number of protons in the nucleus of an atom. the atomic number increases by one as we go from one element to the next. thus, this makes it easy to ascertain how many undiscovered elements may be there between two known elements.2.) Mendeleev's periodic table was made according to increasing atomic masses. we know that of an element have same chemical properties and atomic number, but different atomic masses. So, the concept of isotopes can not be satisfied.The Modern periodic table is according to increasing atomic numbers. Therefore, the problem of isotopes is easily dealt with.
Isotopes of Chlorine-35 and 37 have different atomic wt. but same atomic number. And in the modern periodic table, the elements are arranged in order of their atomic number AND NOT atomic wt. hence, Chlorine-35 and 37 occupy same place in the periodic table.
Yes.The modern periodic table is organized by atomic number. The elements properties are found to be periodic.

Many more elements are known today then when Mendeleev laid out his table. In addition, he arranged his table by atomic mass and there are places in the periodic table where mass does not always increase. An example is between tellurium and iodine.
