Question

.Explain the position of isotopes of elements in Mendeleev's periodic table and modern periodic table



Dont spam ❌ .​​

Answer 1

Explanation:

Since isotopes have the same atomic number they haven't been given any specific position in the modern periodic table. According to Mendeleev's Periodic Law, isotopes of an element must be given separate places in the periodic table because they have different atomic masses.

Answer 2

Answer:

Based on periodic law an isotope is an element which must have a separate place in the periodic table. However there are no places for isotopes in the Mendeleev periodic table. Since isotopes have the same atomic number they haven't been given any specific position in the modern periodic table.
