Verified step by step guidance1
This question is about the historical development of the periodic table, which is a fundamental concept in chemistry but not a calculation problem.
Dmitri Mendeleev is credited with creating the first widely recognized periodic table by organizing elements based on their atomic masses and properties.
To answer the question, recall that Mendeleev published his periodic table in the 19th century, specifically in the year 1869.
This date is significant because it marked the first time elements were arranged in a systematic way that predicted the properties of undiscovered elements.
Therefore, the correct answer to when Mendeleev first published his periodic table is 1869.
