Why is platinum at the bottom of the reactivity series?

They require more energy to be separated from their ores, and become stronger reducing agents, while metals present at the bottom of the series are good oxidizing agent. Displaces H2 gas from water, steam and acids and forms hydroxides. Silver, gold, and platinum are metals with the least reactivity.

Is platinum most 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 reactive yes or no?

Platinum is one of the least reactive metals. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal.

Is platinum more reactive or less reactive?

Platinum, however, is less reactive than copper and so cannot displace copper from a copper sulfate solution.

What elements have the highest reactivity?

Reactivity of Group 1 Elements Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.

What is the least reactive element?

Noble gases
Noble gases are the least reactive of all known elements. Their outer energy levels are full because they each have eight valence electrons. The only exception is helium, which has just two electrons.

Why platinum is not reactive?

Platinum is one of the “noble” metals that is known for being highly unreactive. Platinum is so stable that it cannot even be attacked by most acids – only the strongest acid solutions, such as aqua regia (a mixture of anhydrous nitric and hydrochloric acids) can cause it to react.

Which is less reactive platinum or gold?

The more reactive the metal, the more rapid the reaction is. Platinum is placed below gold in the reactivity series.

Which metal is less reactive gold or platinum?

Both gold and platinum are known as noble metals. Gold is much more less reactive than platinum. They dissolve in aquaregia ( 3 parts of HCl and 1 part of HNO3).

Which element is most reactive and why?

Alkali metals (situated far away from transitional metals and noble gases) are the most reactive elemental group. Cesium is second from the bottom of this group, with 6 electron shells, so it fits all the characteristics of a reactive atom, therefore making it the most reactive element.

How can you tell which metal is more reactive?

The primary difference between metals is the ease with which they undergo chemical reactions. The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive.

Which element is not reactive at all?

Noble gases are the least reactive of all known elements. That’s because with eight valence electrons, their outer energy levels are full. The only exception is helium, which has just two electrons.

Which is more reactive N or NE?

This Answer Now. Neon: 1s2, 2s2, 2p6. As we can see from the electronic configurations, neon has a fully filled outer shell and hence is non-reactive. Hence, it is much easier for oxygen to complete its octet, as compared to nitrogen and that is why, oxygen is more reactive than nitrogen.

Why gold is more reactive than platinum?

Reactions of metals with dilute acids The more reactive the metal, the more rapid the reaction is. Platinum is placed below gold in the reactivity series.
