What is the least reactive element

<ul class="i8Z77e"><li class="TrT0Xe">Group 18 of the periodic table exhibits lowest reactivity.</li><li class="TrT0Xe">Elements with a full outermost valence shell, i.e., those with eight electrons in the outer shell, such as helium, neon, radon and others are the least reactive.</li></ul>

What is the least reactive metal element?

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.

What is the least reactive element and why?

The least reactive element of the periodic table is Noble gases. It is not reacting with the other elements in the normal state, for this reason, they are also called the inert gases.

What is the most reactive and least reactive?

Therefore, gold (Au) is the least reactive metal and potassium (K) is the most reactive metal. Q. Identify the most reactive and least reactive metals among the following. Q.

What are the 5 least reactive metals?

The least reactive metals would be Platinum, Gold, Palladium, Osmium and Silver and in the decreasing order.

What are the 3 most reactive elements?

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. Lithium, sodium, and potassium all react with water, for example.

Why is gold the least reactive metal?

Gold is least reactive metal because of higher standard reduction potential value.

What are the top 10 most reactive elements?

Top 10 Most Reactive Elements

Aluminum. Atomic number is 13. It's symbol is Al.
Zinc. Iron's symbol is Fe. It's atomic number 26. Iron is on of the Earth's most common element by mass.
Iron.
Copper. Lead is located in the carbon group. Melting point is 625 degrees Fahrenheit. It's symbol is Pb. ...

Which is least reactive copper or silver?

Copper is more reactive than silver so it is placed above silver.

What are the three least reactive metals?

Silver, gold, and platinum are metals with the least reactivity.

Which elements are more or less reactive?

The halogens, alkali metals, and alkaline earth metals are highly reactive.

The most reactive element is fluorine, the first element in the halogen group.
The most reactive metal is francium, the last alkali metal (and most expensive element).
The least reactive elements are the noble gases.

Which element is least reactive in water?

The correct answer is Option 2, i.e Lithium. All the elements given in the option are alkali metals. Among these lithium is less reactive with the water.

Is Lithium the least reactive?

Lithium is the least reactive because it is the one with the least electrons. That means the electrons are closer to the nucleus and therefore more attracted to it.

Is zinc the least reactive?

Gold is the least reactive metal as compared to copper, zinc and magnesium.

Which of the following are least reactive?

Metals like copper, silver and gold are at the bottom of the reactivity series and it is least reactive. Q.

What are the 4 most reactive metals?

Explanation: Alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). As you move down the column, the metals become more reactive because the nucleus gains more electrons and protons (more electron levels), weakening their electrostatic force.

Why is lithium less reactive?

Lithium is an alkali metal having higher value of oxidation potential and can easily lose electrons and do not react vigorously with water like the other alkali metals.

Why is the most reactive element?

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.

Which is more reactive iron or copper?

Iron is more reactive than copper as copper has less outer shells than iron, so copper is less likely to react with another element as it has a stronger hold over the electrons.
