The physical difference between silver and platinum is in terms of color. Pure silver is more whitish in color while platinum is more grayish than white. Silver has a lower density than platinum.
The chemical symbols for gold, silver, and platinum are Au, Ag, and Pt, respectively.
Platinum readily forms alloys with metals like iridium and ruthenium. These alloys enhance the properties of platinum, such as improving its hardness and resistance to corrosion. Additionally, platinum can be combined with metals like gold and silver to create attractive jewelry pieces.
the physical properties of magnesium can best be describes as a: shiny metal b: silver, shiny, metallic solid c: dissolves in viegar d: reacts with vinegar
What is the physical properties for fine sea salt
u can find out on ur own.
Yes, the luster of silver jewelry is a physical property. Luster refers to the shininess or reflective quality of a material's surface, which is a characteristic that can be observed without changing the chemical composition of the silver.
A silver spoon has physical properties such as being shiny, metallic, malleable, and a good conductor of heat and electricity.
Silver is not a property. It is a substance with chemical and physical properties. Silver colour is a property (physical)
Silver is a soft metal. Platinum is a similar color but does not change its shape easily and does not tarnish. Platinum is worth more than silver and gold.
Gray and shiny
If you look at the periodic table,and silver's location (amongst gold, palladium, rhodium, & platinum, amongst others') and you look at some of it's properties (soft like gold, platinum like catalytic activity, highest electrical and thermal conductance of ANY pure element) then silver is most like both gold and platinum. It conducts like gold, and shares with it many similar physical properties (soft, malleable and dense). Also, silver can behave much like the platinum group metals (with the exception of rhodium), in it's catalytic abilities. Although not noble, it has many noble'esque qualities. So I'd say, silver is most like palladium, then platinum, followed closely by gold. This, having assigned characteristic, and weighing them proportionally in the best way I know how.
grayish silver metalloid
grey solid
Yes, the luster of platinum jewelry is a physical change. The luster is a result of the surface properties of the platinum metal, such as its reflection of light, without any alteration to the chemical composition of the metal.
Silver, platinum, and mercury, they are the closest molecularly to gold.
Silver metallic color is a physical property, as it relates to the way light is reflected off the surface of the silver metal. Chemical properties, on the other hand, involve changes in the chemical composition of a substance.
