Overview. Mercury is a transition metal. A transition metal is one of the elements found between Groups 2 (IIA) and 13 (IIIA) on the periodic table. The periodic table is a chart that shows how chemical elements are related to one another.Mercury has long been known as quicksilver, because it is a silver liquid.ercury is the only liquid metal. In fact, there is only one other liquid element, bromine. Bromine is a non-metal. Mercury can be frozen (changed into a solid) at a temperature of â38.85Â°C (â37.93Â°F). It can be changed into a gas (boiled) at 365.6Â°C (690.1Â°F). Its density is 13.59 grams per cubic centimeter.
Phosphorus atoms have 15 electrons and 15 protons with 5 valence electrons in the outer shell. Characteristics and Properties. Phosphorus is a highly reactive element and, as a result, is never found on Earth as a free element.Elemental phosphorus comes in various allotropes (different crystal structures) including white, red, violet, and black phosphorus. The two major forms of phosphorus are white and red.hosphorus atoms have 15 electrons and 15 protons with 5 valence electrons in the outer shell. Characteristics and Properties. Phosphorus is a highly reactive element and, as a result, is never found on Earth as a free element.
