Correct Answer: Element 101
Solution : The correct option is Element 101 .
In 1955, the synthetic element provisionally named Mendelevium (symbol: Md, atomic number: 101) was indeed named in honour of Dmitri Mendeleev, the Russian chemist who created one of the first periodic tables. Mendeleev's work laid the foundation for the modern periodic table, which organises elements based on their atomic number and properties. Mendelevium is a transuranium element, meaning it has an atomic number greater than that of uranium.
