Platinum is placed below gold in the
.Silver, gold, and platinum are metals with the least reactivity.Platinum is chemically inert and will not oxidize in air at any temperature. It is resistant to acids and is not attacked by any single mineral acid but dissolves readily in aqua regia. The metal is rapidly attacked by fused alkali oxides and by peroxides and will react with fluorine and, at red heat, with chlorine.

Is platinum a reactive metal?
Platinum is chemically inert and will not oxidize in air at any temperature. It is resistant to acids and is not attacked by any single mineral acid but dissolves readily in aqua regia. The metal is rapidly attacked by fused alkali oxides and by peroxides and will react with fluorine and, at red heat, with chlorine.
Which is the least reactive metals?
Platinum is the least reactive metal. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Consequently, platinum is often found chemically uncombined as native platinum.
Is platinum more inert than gold?
Platinum is even more inert & non-reactive than gold. We craft platinum jewelry in Pt 950 only, i.e. 95% Platinum which is a much higher purity than even 22K Gold, which is only 91.6% pure.
Why is platinum less reactive than gold?
Metals which are higher in the electrochemical series displace metals which are lower. Hydrogen has an electrode potential of +0.00. As to which is more reactive platinum or gold the answer is platinum with an electrode potential of +1.18 while gold has an electrode potential of +1.70.

What is gold’s reactivity?
Reactivity. Gold is one of the least reactive elements on the Periodic Table. It doesn’t react with oxygen, so it never rusts or corrodes. Gold is unaffected by air, water, alkalis and all acids except aqua regia (a mixture of hydrochloric acid and nitric acid) which can dissolve gold.
Which is the least reactive element in reactivity series?
We know that reactivity series is arranged in such a way that as we move from bottom to top, reactivity of the metals increases. As we can see in the series, out of all the given options gold is the least reactive metal.
Why is gold least reactive?
Gold is unreactive because the nucleus of the gold is heavy such that the electrons must travel at the speed of light. The 6s electrons in the gold are less accessible for bonding and their energy is dissimilar to many reactants. This gold makes unreactive.
Platinum or Gold? Which Precious Metal Will Set The Pace In 2021?
Images related to the topicPlatinum or Gold? Which Precious Metal Will Set The Pace In 2021?
Which is the most reactive and least reactive metal?
Solution : Most reactive metal : K (potassium) , Least reactive metal : Au (gold).
Which metal is most reactive?
The most reactive metal on the periodic table is francium. Francium, however, is a laboratory-produced element and only minute quantities have been made, so for all practical purposes, the most reactive metal is cesium.
Is platinum better than gold?
Gold: Value. Platinum is almost always more valuable than gold. It’s a rarer metal, and platinum rings have higher densities and purities than gold rings. You also need more platinum to make a ring, so they often cost 40-50% more than gold.
Why is platinum reactive?
Platinum is rapidly attacked by fused alkali oxides and peroxides and also by fluorine and chlorine at about 500 °C. It is capable of absorbing large volumes of hydrogen, and, with palladium, it is one of the most reactive platinum metals.
Is platinum a gold?
While Platinum is a naturally white metal, White Gold is made by combining pure gold (which is yellow in colour) with alloying metals such as Palladium. Because of the yellow metal content, White Gold is actually slightly grey/off-white in colour. This can be corrected by a surface treatment called Rhodium plating.
Which of the following are least reactive?
Black phosphorus is thermodynamically most stable form of phosphorus as it is a highly polymerised form of phosphorus. Hence it is least reactive.
Why is gold and silver least reactive?
silver and gold is a good conductor of electricity because of its sea of delocalised electrons between the layers of metal ions. However it is not highly reactive because you would need a lot of energy to break the metallic bonds within each of those layers.
Can platinum rust?
Known as the precious metals, platinum, gold and silver are all pure metals, therefore they contain no iron and cannot rust.
Which is the correct order of reactivity series?
3) There is the order of reactivity of metals and in order to remember this order, one has to recite this order in any possible simple form. The order of reactivity of metals is as follows, Potassium > Sodium > Lithium > Calcium > Magnesium > Aluminium > Zinc > Iron > Copper > Silver > Gold.

What are reactive metals?
Reactive metal is a group of metal elements that can form a reaction with acids, water, mineral acids and powerful oxidizing acids. This group can be identified with the activity or reactivity series, which determines the most reactive metals from highest to lowest.
Is platinum less reactive than hydrogen?
Many transition metals such as iron, chromium, nickel, tin, zinc, and lead are more reactive than hydrogen. However, metals like gold, copper, and platinum are less reactive than hydrogen. Anything below lead will NOT react with hydrogen.
