Note:
(a) "Tennessee is the second US state to be recognized with an element; California was the first. Element names can come from places, mythology, names of scientists or traits of the element. Other examples: americium, einsteinium and titanium."
(i) californium
https://en.wikipedia.org/wiki/Californium
(symbol Cf and atomic number 98; first made in 1950 at the University of California Radiation Laboratory in Berkeley)
(ii) americium
https://en.wikipedia.org/wiki/Americium
(symbol Am and atomic number 95; first produced in 1944 by the group of Glenn T. Seaborg from Berkeley, California, at the metallurgical laboratory of University of Chicago)
(iii) titanium
https://en.wikipedia.org/wiki/Titanium
(symbol Ti and atomic number 22; was discovered in Cornwall, Great Britain, by William Gregor in 1791 and named by Martin Heinrich Klaproth for the Titans of Greek mythology)

(b) "moscovium (mah-SKOH'-vee-um), symbol Mc, for element 115, and tennessine (TEH'-neh-seen), symbol Ts, for element 117. The discovery team [for both new elements] is from the Joint Institute for Nuclear Research in Dubna, Russia, the Oak Ridge National Laboratory and Vanderbilt University in Tennessee, and the Lawrence Livermore National Laboratory in California."

Dubna
https://en.wikipedia.org/wiki/Dubna
(a town in Moscow Oblast; home to the Joint Institute for Nuclear Research [JINR], an international nuclear physics research center and one of the largest scientific foundations in the country)

(c) periodic table
https://en.wikipedia.org/wiki/Periodic_table
("The first 94 elements exist naturally, although some are found only in trace amounts and were synthesized in laboratories before being found in nature. Elements with atomic numbers from 95 to 118 have only been synthesized in laboratories")

Note where elements 115 to 118 are located in the table.
