Which metal is the least reactive? Platinum is the least reactive metal.Complete answer:
Platinum is the least reactive of all the options. Aluminium, iron are also formed in combined forms in the natural surroundings. Whereas Platinum is not found in combined state at natural sites.– Potassium metal has more number of shells compared to sodium and thus it becomes easy to remove one electron from its outermost orbital ( less ionization enthalpy). – So, out of given metals, Potassium is the most reactive metal. Therefore, potassium is the most reactive metal among the given options.

Which 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.
Which is the least reactive metal among the following?
Explanation: According to the reactivity series of metals, silver lies at the bottom, hence it is least reactive than others.
What is the most reactive metal least reactive?
In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements. The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive.
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 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.
Which is the least reactive metal gold or platinum?
Platinum is the least reactive metal. So, platinum is less reactive than gold.
Which is the most reactive metal?
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 copper or silver?
The correct answer is Copper.
Which is least reactive metal silver or lead?
Therefore, the correct answer is (B) Silver.
Which metal is most non reactive?
Helium is the least reactive non metal. Helium is a chemical element with the symbol He and atomic number 2.
What is the most reactive metal least reactive Brainly?
Answer. Least reactive metals –gold, silver, titanium, palladium, platinum.

Which of the following elements is least reactive Brainly?
Helium is the least reactive element in the reactive series.
Why is copper not reactive?
On the other hand, copper is placed lower than hydrogen in the activity series of metals (which means that it is less reactive than hydrogen) and therefore does not react with HCl .
