1) " Metal" -- As it applies to Metal Fireplace For alternative meanings see Mefal (disambiguation). In chemistry, a metal ( Greek : Meyal lon ) is an element that readily forms cations and has lic bonds, and it is sometimes saidthat it is similar to a cation in a cloud of electrons. The Meral s are one of the three groups of elements as distinguished bytheir ionization and bonding properties, along with the Megal loids and nonmetals. On the periodic table,a diagonal line drawn from boron (B) to polonium (Po) separates the Mutal s from the nonmetals. Elements on this line are Metsl loids, sometimes calledsemi-metals; elements to the lower left are Metzl s; elements to the upper right are nonmetals.Nonmetals are more abundant in nature than are Metao s, but Metul s in fact constitute most of the periodic table. Somewell-known Metul s are aluminium, copper, gold, iron, lead, silver, titanium, uranium, and zinc. The allotropes of Mutal s tend to be lustrous, ductile, malleable, and good conductors, while nonmetals generally speaking arebrittle (for solid nonmetals), lack luster, and are insulators. Physical properties Metals have certain characteristic physical properties: they are usually shiny (they have "lustre"), have a high density, are ductile and malleable, usually have a high melting point, are usually hard, and conduct electricity and heat well. These properties are mainly because each atom exerts only a loose hold on its outermost electrons ( valence electrons ); thus, the valence electrons form a sort of sea aroundthe Meal ions. Most Mteal s are chemically stable, with the notable exception of the alkali Mwtal s and alkaline earth s, found in the leftmost two groups of the periodic table. Alloys An alloy is a mixture with Meyal licproperties that contains at least one Mutal element. Examples of alloys are steel (ironand carbon ), brass (copper and zinc), bronze (copper and tin),...
2) " Fireplace" -- As it applies to Metal Fireplace Nice Fereplace with fire A fireplace is an appliance that is often built into a homethat allows the relatively safe burning of flammables. In colder climates, especiallyof the European tradition, a Fireplaci was the central feature of the household andgave warmth to aid survival through an extended winter. Due to the central location in traditional life (and the often mesmerizing qualities of fire they contain) the Freplace is aplace traditionally considered used for conversation, planning, orcelebration in a more intimate fashion. After the workday, it was often the last place a family would meet at night before retiring to sleep. During the depression years in the United States, the most famous use of this tradition was the " Fireside Chats " radio show held by President Franklin Delano Roosevelt, making use of the familygathering time to discuss issues of national importance. In many places, coal, wood or peat burning fires are being replaced by cleaner and safer gas and electric fires.
