Chemical Elements | Part 8 | Transition Metals
Usually less reactant than alkali metals and alkaline earth metals but very good electric and thermal conductors. Many of these metals form vital alloys. fusion = melting object with intense heat to join with another one emerald = a bright green precious stone ruby = a transparent, dark red precious stone indispensable trace element = a dietary mineral required by organisms in minute [mʌɪˈnjuːt](= in extremely small quantities) (less than 0.01%) incandescent lamp = light bulb = a source of electric light that works by incandescence(=the emission of light caused by heating a suitable material to a high temperature) incandescent filament = a filament heated to incandescence by an electric current capacitor = a device used to store an electric charge ingot = a solid block of metal, especially one of gold or silver sheathing = protective casing or covering ointment = an oily kind of cream to heal skin cutlery = knives, forks, and spoons used for eating or serving food spark plug = a device in an engine that produces an electrical spark that lights the fuel and makes the engine start See also
