Which elements are the least reactive?

Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.

Which metals are least reactive and why?

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.

How do you find least reactive?

Explanation: 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.

What are the top 3 most reactive metals?

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.

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.

What are the most reactive metals in the periodic table in order?

The most reactive metals in the periodic tables are the alkali metals, followed by the alkaline earth metals. Was this answer helpful?

Which is the most unreactive metal?

Gold is the most unreactive metal of the above-given options.

What is the order of reactivity in the periodic table?

Chemical reactivity of the elements

Period - reactivity decreases as you go from left to right across a period. The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity.

Which is the least reactive metal gold or platinum?

Platinum is placed below gold in the reactivity series.

What are the two most reactive metals?

Metallic character is associated with the elements that are metals. Most of the metals are hard, have high melting/boiling points, and are malleable as well as ductile. Among Sodium and Potassium, Potassium is the most reactive metal as it has lower ionization energy than sodium due to its bigger atomic size.

Which of the following is more reactive?

Hence, ICl is most reactive.

What is the most reactive nonmetal in order?

The most reactive nonmetal is fluorine.

Where are the least reactive metals located on the periodic table?

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.

Why is the reactivity series in that order?

The reactivity series of metals is a chart listing metals in order of decreasing reactivity. In general, the more reactive a metal is: the more vigorously it reacts with other substances. the more easily it loses electrons to form positive ions (cations)

Which of the following metals is most reactive?

Calcium or potassium which are present towards the top of the reactivity series are highly reactive metals as they can displace metals present below. From the given options, calcium is placed the highest in the activity series, and so, is the most reactive metal.
