Are you looking for an answer to the topic “Which is the least reactive in the given metals Class 8?“? We answer all your questions at the website Ecurrencythailand.com in category: +15 Marketing Blog Post Ideas And Topics For You. You will find the answer right below.
Answer: Gold does not corrode in air. It is the least reactive metal.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.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.

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.
Which metal is the least reactive in the 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.

What are the 2 least reactive metals?
Silver, gold, and platinum are metals with the least reactivity.
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.

The reactivity series.
| Element | Reaction with dilute acids |
|---|---|
| Copper | Very slowly |
| Silver | Barely reacts |
| Gold | Does not react |
Why is gold the least reactive metal?
Since the 6s orbital with one electron is contracted, this electron is more tightly bound to the nucleus and less available for bonding with other atoms. The 4f and 5d orbitals expand, but can’t be involved in bond formation since they are completely filled. This is why gold is relatively unreactive.

Which metal is less reactive copper or iron?
Copper is less reactive than iron. Since, according to the atomic structure, iron has four unpaired shells in its three sub shells, while copper only has one electron. As a result, iron can react faster than copper.
Where are the least reactive elements on the periodic table found?
Noble gases are nonreactive, nonmetallic elements in group 18 of the periodic table. Noble gases are the least reactive of all elements. That’s because they have eight valence electrons, which fill their outer energy level.

Which is the most reactive metal answer?
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.
Which is the least reactive metal gold or platinum?
Platinum is the least reactive metal. So, platinum is less reactive than gold.
Why is silver the least reactive metal?
Refrences. Explanation: According to the reactivity series of metals, silver lies at the bottom, hence it is least reactive than others.
What is one of the least reactive chemical elements?
The least reactive elements are the noble gases. Within this group, helium is the least reactive element, forming no stable compounds. Metal can have multiple oxidation states and tend to have intermediate reactivity. Metals with low reactivity are called noble metals.
Which of the following elements is least reactive Brainly?
Helium is the least reactive element in the reactive series.
Which of the following group of elements are least reactive?
Group 18 elements are the least reactive elements.
Which of the following is least reactive with oxygen?
The least reactive metal with oxygen in the list is C. Copper.
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.
