No, Dmitri Mendeleev did not know about isotopes. When he created the Periodic Table in the 1860s, the concept of isotopes—atoms of the same element with different numbers of neutrons—had not yet been discovered, as it was introduced later in the early 20th century. Mendeleev's work was based on the understanding of elements as unique entities, defined by their Atomic Mass and chemical properties, without the knowledge of isotopic variations.
What else can I help you with?
Did mendeleev know about protrons?
No, Dmitri Mendeleev did not know about protons. The concept of protons was not discovered until later in the 20th century, after Mendeleev's time. Mendeleev is most famous for creating the periodic table of elements.
What did Dimtri Mendeleev did not know about the periodic table?
Only some elements were discovered during the life of Mendeleev.
What are the disadvantages of Johann doberiners periodic table?
Mendeleev ignored the order of atomic mass for few elements. He was not able to fix those elements which were having isotopes.
Was helium included in Mendeleev's original periodic table?
No, he did not know about it. Helium was discovered in spectrographs of the Sun in 1868 and isolated in 1895. Mendeleev's original table skipped from hydrogen (1) to lithium (3).
Name the elements whose atomic masses corrected by mendeleev?
The atomic masses corrected by Mendeleev are those of beryllium, indium, and uranium. Mendeleev was able to accurately predict the properties of these elements based on their corrected atomic masses.
Did mendeleev know about protrons?

What did Dimtri Mendeleev did not know about the periodic table?
Only some elements were discovered during the life of Mendeleev.
How did Mendeleev know where to leave space in his table?
Mendeleev arranged the elements in order of increasing related Atomic Mass
What did Dmitri Mendeleev do during the Industrial Revolution?
Mendeleev laid the foundation for theperiodictable that we know today
What are the disadvantages of Johann doberiners periodic table?
Mendeleev ignored the order of atomic mass for few elements. He was not able to fix those elements which were having isotopes.
The first periodic table was arranged by?
Demitri Mendeleev. He arranged it by atomic mass
How do you isotopes in a sentence?
No one will ever know.
Was helium included in Mendeleev's original periodic table?
No, he did not know about it. Helium was discovered in spectrographs of the Sun in 1868 and isolated in 1895. Mendeleev's original table skipped from hydrogen (1) to lithium (3).
How do you know whether not atoms are isotopes?
Isotopes of a chemical element have a similar number of protons but a different number of neutrons.
What are some uses of isotopes in chemistry?
I Don't know
How do you know that hydrogen has isotypes?
every element has isotopes.
What is Doctor Mendeleev's full name?
Dmitri Mendeleev
