What is the least reactive material?

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.

What are the least reactive metals?

Silver, gold, and platinum are metals with the least reactivity. They are found in nature.

Where are the least reactive?

The reactivity of an element can be determined by looking at the electron configuration of the element. The least reactive elements are those who have a full outermost valence shell ie they have 8 electrons in the outer shell so elements such as helium, neon, radon or the transition elements.

Which metal is not most reactive?

These elements react explosively with air and water, and are nearly impossible to isolate for this reason. The most reactive non-metal is hands down element 9, Fluorine. I suppose the most reactive metal would be element 55 (Cs) Cesium or 87 (Fr) Francium, both being in the first column or the periodic table.

What is the least reactive non metal?

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 least reactive gold or platinum?

A metal below hydrogen in the reactivity series will not react with dilute acids. Platinum is placed below gold in the reactivity series.

What is the most and least reactive metal?

In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a greater tendency to lose electrons and form positive ions ….The reactivity series.

Element	Reaction with water
Lithium	Quickly
Calcium	More slowly

What is the least reactive group?

Noble gases
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 least reactive non metal?

Helium
Helium is the least reactive non metal. Helium is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert gas.

Which is the least reactive metal in the reactivity series?

As we can see in the series, out of all the given options gold is the least reactive metal.

Which is the least reactive alkali metal?

lithium (Li)
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.

What is the least reactive noble gas?

Overview. Noble gases are nonreactive, nonmetallic elements in group 18 of the periodic table. They include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). Noble gases are the least reactive of all known elements, because with eight valence electrons, their outer energy levels are full.
