The Periodic Table was invented by Dmitry Mendeleyev. He grouped every known element and he used this table to predict the existence of other several elements. Mendelevium name pays homage to Dmitry Mendeleyev.
The name curium is derived from the name of the well known family of scientists - Curie.

An atom is the smallest amount of an element that still retains that element's properties. An atom is made up of protons, neutrons, and electrons. Protons have a positive charge, and are part of the nucleus. Neutrons have no charge, and are part of the nucleus as well. Electrons have a negative charge, and orbit the nucleus. Scientists also believe that protons and neutrons are made up of quarks.
Curium was named after Marie and Pierre Curie. The element was not discovered by Marie and Pierre Curie, but Curium is radioactive and Marie and Pierre Curie were well known for their pioneering work regarding radioactivity.
Mendelevium
If you mean Dimitri Mendeleev. Then it's the element: mendelevium

I assume you know that Dmitri Mendeleyev was the man that discovered the periodic table and left spaces for future findings of elements. He also has an element names after him. He wrote a book. He is a great guy.
ascending atomic weight, what the element reacts to and how
He wrote information that is found on the periodic table: the atomic number, the element, the mass number and etc.
He is out of his element. The scientists have isolated a new element.
the scientists can synthesize a transmutation element by artificial transmutation of a lighter element
Relationships between the properties and the element, lack of permanent position
what element is used and why do scientist chose it
There were gaps in the periodic table a hundred years ago because investigators had not discovered some elements yet, though there was a "place" for them in the array. Recall that through the genius of Mendeleyev, the elements had been given an "order" owing to their chemical properties. By creating a "chart" (the first periodic table), Mendeleyev could see where elements "would be" though none had yet been discovered. He could predict that eventually an element would appear "here" on the table and would have a "these" properties because of the arrangements in the array or table of element.
scientists knew that oxygen was a element as it had the atoms of only O i,e. oxygen and helped in increase in combustion
