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, Which metal is more reactive than copper?
Displacement order
Magnesium is more reactive than copper, so magnesium can displace copper from a copper sulfate solution to create magnesium sulfate.
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.

Is sodium or copper more reactive?
The most reactive metals, such as sodium, will react with cold water to produce hydrogen and the metal hydroxide: … Copper and silver will react with nitric acid; but because nitric acid is an oxidizing acid, the oxidizing agent is not the H+ ion as in normal acids, but the NO3− ion.
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 Aluminium more reactive than copper?
Aluminium appears less reactive than copper. … The protective oxide layer forms instantly the aluminium is exposed to the air.
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.
Why is copper not reactive?
In this case, zinc is more reactive than hydrogen, but copper is less reactive than hydrogen. It means that zinc can displace hydrogen from HCl, but copper cannot. … So that makes zinc generally more reactive than copper, and in relation to hydrogen.
What is more reactive magnesium or copper?
During the reaction: For example, magnesium is more reactive than copper. When a piece of magnesium is dipped into blue copper sulfate solution: brown copper coats the surface of the magnesium.
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.
What copper is more reactive than silver?
Copper is more reactive than silver so it is placed above silver.
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.
Why is silver not reactive?
Silver is a rather unreactive metal. This is because its filled 4d shell is not very effective in shielding the electrostatic forces of attraction from the nucleus to the outermost 5s electron, and hence silver is near the bottom of the electrochemical series (E0(Ag+/Ag) = +0.799 V).
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.
Why is aluminum is more reactive than copper?
Aluminium has more free electrons for reactions compared to copper with less free electrons.
Which metal is less reactive copper or zinc?
Zinc is more reactive than Cu and Fe metal. Iron displaces copper from its solution. Therefore, copper is less reactive than iron. Copper does not displace any metal therefore it is the least reactive.
