Question 14

Named after American nuclear
chemist Glenn T. Seaborg

Answer 14

SEABORGIUM

Question 15

a synthetic element that can only be made a
few atoms at a time, does not have a commercial use. At present, it is only used in research.

Answer 15

RUTHERFORDIUM

Question 16

Named after Danish Physicist
Niels Bohr.

Answer 16

BOHRIUM

Question 17

An extremely radioactive
synthetic element.
Since only a few atoms of
tennessine have ever been
produced, it currently has no uses
outside of basic scientific
research.

Answer 17

DARMSTADTIUM

Question 18

only used for
research purposes in scientific
studies, to better understand its
properties, and to create heavier
elements.

Answer 18
