Answer 1

Answer:

Na, Zn, Cn, Hg

Explanation:

Sodium is a chemical element with the symbol Na (from Latin natrium) and atomic number 11. therefore its symbol is Na.

Zinc and chemical symbol Zn come from the Latin Zincum, which means "white thin layer" or "white sediments". therefore its symbol is Zn.

Hydrargyrum, the Latin name for Mercury (Hg), was taken from the original Greek hydrargyros, which meant “water silver.” Also historically known as “quicksilver,” elemental mercury is a shiny silver metal that is liquid at room temperature. therefore its symbol is Hg
