Answer 2

Answer:

mercery - Hg is the modern chemical symbol for mercury. It comes from hydrargyrum, a Latinized form of the Greek word (hydrargyros), which is a compound word meaning "water-silver" – since it is liquid like water and shiny like silver.

tungsten - The word tungsten means “heavy stone” in Swedish. The chemical symbol for tungsten is W, which stands for wolfram. Element Tungsten (W) belongs to group 6, atomic Number 74 and d−block.

bromine - Bromine is a chemical element with the symbol Br and atomic number 35. ... The mass of bromine in the oceans is about one three-hundredth that of chlorine. At standard conditions for temperature and pressure it is a liquid; the only other element that is liquid under these conditions is mercury.

Atomic number (Z): 35

Atomic radius: empirical: 120 pm

Density (near r.t.): Br2, liquid: 3.1028 g/cm3

Heat of vaporisation: (Br2) 29.96 kJ/mol

Led - Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point.
