Mercury (Hg) Element Facts - Atomic Number 80, Symbol Hg, Atomic Weight 200.59 #3585137 (License: Personal Use)

This periodic table tile displays mercury (Hg), a dense, silvery-white liquid metal at room temperature and the only metal that is liquid under standard conditions. Its atomic number is 80, atomic weight is 200.59 u, and its electron configuration is [Xe] 4f¹⁴ 5d¹⁰ 6s², reflected in the shell notation 2-8-18-32-18-2 shown on the tile. Mercury is historically used in thermometers, barometers, and electrical switches, though modern applications are limited due to its high toxicity.

This image is commonly used in educational chemistry resources, science websites, and digital textbooks to illustrate elemental data for mercury. It serves users seeking quick reference on atomic structure, physical properties, or periodic trends-especially students, teachers, and researchers.
