Noble gases are the least reactive of all known elements. That’s because with eight valence electrons, their outer energy levels are full. The only exception is helium, which has just two electrons.
for instance, What is the least reactive metal?
Platinum is the least reactive of all the options. Aluminium, iron are also formed in combined forms in the natural surroundings.
significantly, Which is more reactive N or NE?
Neon: 1s2, 2s2, 2p6. As we can see from the electronic configurations, neon has a fully filled outer shell and hence is non-reactive. … Hence, it is much easier for oxygen to complete its octet, as compared to nitrogen and that is why, oxygen is more reactive than nitrogen.
also Which family is the most reactive?
The family that contains the most reactive metals are the alkali metals.
Which is the least reactive element in period 3? Silicon. Silicon (symbol Si) is a group 14 metalloid. It is less reactive than its chemical analog carbon, the nonmetal directly above it in the periodic table, but more reactive than germanium, the metalloid directly below it in the table.

Why is copper the least reactive metal?
Copper is below zinc in the reactivity series so will be unable to displace it in the compound and there will be no reaction.
Which is the least reactive metal silver or gold?
The order of intensity of reactivity is known as reactivity series. Reactivity of element decreases on moving from top to bottom in the given reactivity series. In the reactivity series, copper, gold, and silver are at the bottom and hence are least reactive.
How will you show that silver is less reactive than copper?
When silver is dipped in a copper sulphate solution, no reaction occurs. This means silver cannot displace copper from the copper sulphate solution. Hence, it shows that silver is chemically less reactive than copper.
Is potassium the most reactive metal?
– So, out of given metals, Potassium is the most reactive metal. Therefore, potassium is the most reactive metal among the given options.
Which metal is highly reactive?
Caesium, the most reactive metal in the periodic table, reacts extremely violently – hence why it can’t be demonstrated in a classroom! This can be compared to other common metals, such as iron and copper, which produce no reaction when dropped into water.
Which is more reactive Cl or NE and why?
It is easier for the nucleus to attract 7 electrons than 8 electrons. More is the number of electrons , less is the ability to be attracted to the nucleus. Hence Cl- is bigger than Cl atom.
What are the 2 most reactive groups?
The two most reactive groups of elements are the alkali metals and the halogens, because of their valence electrons.
What is the most non reactive metal family?
Group 18: Noble Gases
Group 18 elements are nonmetals called noble gases (see Figure below). They are all colorless, odorless gases. Their outer energy level is also full, so they are the least reactive elements.
Which is the most reactive nonmetal family?
1. What are the halogens? The halogens are a group of elements found in group 17 of the periodic table. Their name means salt-producer, and they are the most reactive non-metal elements.
What is the most reactive element in period 3?
Chlorine, sulfur, phosphorus, and silicon are all strongly oxidizing… And that’s seven out of eight elements……..
How do you know which element is 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 nonmetal family is the most reactive?
Halogens are the most reactive nonmetals on the periodic table. The halogens are so reactive due to their electronic configuration.
What metal is less reactive than copper?
Platinum, however, is less reactive than copper and so cannot displace copper from a copper sulfate solution.
Is zinc more reactive than copper?
The metals that form positive ions by losing electrons more readily. A more reactive metal displaces a less reactive metal from salt solution. Such reactions are called displacement reactions. … Therefore, zinc is more reactive than copper.
What is the most reactive metal in order?
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.
Which is the most reactive metal family?
The family that contains the most reactive metals are the alkali metals.
Why is magnesium more reactive than copper?
Due to the relative reactivity of metals, given in the reactivity series, when combined they compete to form ionic compounds with other chemicals. More reactive metals will displace (push out) less reactive metals from metal salt compounds. … The magnesium displaces the copper as it is a more reactive metal.
What is the least reactive metal in Period 3?
Silicon. Silicon (symbol Si) is a group 14 metalloid. It is less reactive than its chemical analog carbon, the nonmetal directly above it in the periodic table, but more reactive than germanium, the metalloid directly below it in the table.
Which of these is less reactive than copper?
Platinum, however, is less reactive than copper and so cannot displace copper from a copper sulfate solution.
What copper is more reactive than silver?
Copper is more reactive than silver so it is placed above silver.
