2.

"Quackism" is a recently discovered element with the symbol Q. It is located in group 7A in the same group as chlorine, bromine and iodine.

"Jokim" is a recently discovered element with the symbol J. It is located in group 4A of the periodic table with carbon and silicon.

Draw the Lewis structure of SeQ₂. (1 atom of selenium and two atoms of quackism.)
