Oxygen is placed in the second period of the Mendeleev table.
Mendelevium
Element 101, mendelevium, was named after Dmitri Mendeleev, the Russian chemist who is credited with creating the periodic table of elements. Mendeleev's work laid the foundation for organizing and understanding the properties of elements.
Dmitri Mendeleev created the periodic table to organize and classify the elements based on their properties and atomic weights, allowing for easier understanding and prediction of element behavior.

Oxygen is placed in the second period of the Mendeleev table.
The element discovered by Mendeleev in 1871 was germanium. Mendeleev predicted the existence of this element and its properties before it was actually discovered.
The first element of the Mendeleev's periodic table is hydrogen (H).

This element is mendelevium (element 101).
The basic organization structure was by atomic mass, which while it may follow a trend of increasing with each progressing element on the modern table, which is organized by atomic number or number of protons, there are a few exceptions, such as Argon having a greater atomic mass than Potassium, even though Argon has one less proton.
