Zinc-Zinc is a lustrous bluish-white metal. It is found in group IIb of the periodic table. It is brittle and crystalline at ordinary temperatures, but it becomes ductile and malleable when heated between 110°C and 150°C
Calcium-Calcium is a silvery-white, soft metal that tarnishes rapidly in air and reacts with water. Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium
Xenon-Xenon is a rare, odorless, colourless, tasteless, chamically unreactive gas. It was regarded as completely inert until, in 1962, Neil Barlett reported synthesis of xenon haxafluoroplatinate. In a gas filled tube xenon emits blue light when excited by electrical discharge.
Platinum-Platinum is a silver-white metal — it was once known as "white gold." It is extremely resistant to tarnishing and corrosion (which makes it known as a "noble metal") and is very soft and malleable, making it easy to shape; ductile, making it easy to stretch into wire; and unreactive, which means it doesn't oxidize
Silicon-Silicon is the most abundant electropositive element in The Earth's crust. It's a metalloid with a marked metallic luster and very brittle. It is usually tetravalent in its compounds, although sometimes its bivalent, and it's purely electropositive in its chemical behaviour.
