What is the order of reactivity of elements?
The reactivity series follows the order, from most reactive to least reactive:
- Cesium.
- Francium.
- Rubidium.
- Potassium.
- Sodium.
- Lithium.
- Barium.
- Radium.
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.
What is reactivity series in periodic table?
The reactivity series of metals, also known as the activity series, refers to the arrangement of metals in the descending order of their reactivities. The data provided by the reactivity series can be used to predict whether a metal can displace another in a single displacement reaction.
What is the order of reactivity of metals?
The order of reactivity of metals is as follows, Potassium > Sodium > Lithium > Calcium > Magnesium > Aluminium > Zinc > Iron > Copper > Silver > Gold.
Which is highly reactive element?
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). However, francium is an unstable radioactive element, only found in trace amounts.
What is the trick to learn reactivity series?
Short Trick to Remember Reactivity Series
“Please send charlie’s monkeys and zebras in lead & hydrogen cages in mountains securely guarded by Plato.” In the above-given sentence, first alphabet of every word denotes the elements of the reactivity series in order of their reactivity from highest to lowest.
What is the least reactive element?
Helium
Helium is the least reactive of the non-metallic elements. Helium is a chemical element with the atomic number and the symbol . It’s an inert gas that’s colourless, odourless, tasteless, and non-toxic.
Which is the correct order of reactivity series?
Na > Ca > Mg > Al > Zn > Fe > Sn > Pb > Cu > Ag. Was this answer helpful?
What is the easiest way to learn the reactivity series?
- The reactivity series is the series of metals arranged in decreasing order of their reactivity.
- The mnemonic to remember the reactivity series of metal is : Please send cats, monkeys and zebras in lovely happy cages made of silver, gold & platinum.
What are the top 10 least reactive metals?
The least reactive metals would be Platinum, Gold, Palladium, Osmium and Silver and in the decreasing order.
Which element is less 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 is the most non reactive element?
Helium is the least reactive of the non-metallic elements. Helium is a chemical element with the atomic number and the symbol . It’s an inert gas that’s colourless, odourless, tasteless, and non-toxic.

What is the easiest way to learn periodic table?
Memorization Strategies
- Break down the table into sections.
- Spread out the memorization process.
- Learn the elements in a song.
- Make nonsense words made from element symbols.
- Use color to learn element groups.
- Use a mnemonic device to help remember the order of the elements.
Which element is highly reactive?
An element’s reactivity is its tendency to lose or gain electrons. Fluorine (F) is the most reactive metal.
What element is most reactive?
Fluorine: The Most Reactive And Indispensable Chemical Element In Our Daily Lives. Fluorine is a remarkable chemical element – not only because of its unique reactivity.
What is the correct order of decreasing reactivity?
Mg > Al > Zn > Fe.
Which of the following is more reactive?
Fluorine is the most reactive element among the given elements.
Why is K more reactive than Li?
The tendency to loose electrons is greater in potassium than that in lithium. This is because in lithium the valence electrons are closer to the nucleus therefore the attractive forces between nucleus and valence electrons are very strong.
Which group of elements is highly reactive?
alkali metals
The two most reactive groups of elements are the alkali metals and the halogens, because of their valence electrons.
Which element has greatest reactivity?
The most reactive elementary group is alkali metals (situated far apart from intermediate metals and noble gases). Cesium is second from the bottom of this group, has 6 shells of electrons, and it matches the features of a reactive atom, making it the most reactive element.
What are the 5 least reactive metals?
Silver, gold, and platinum are metals with the least reactivity. They are found in nature.
What is the easiest way to learn reactivity series?
How we can learn reactivity series?
In order to remember the reactivity series of metals in the chemistry periodic table, one must remember the first letter of the metals. It denotes the reactivity series of periodic table elements that rearrange from the highest to the lowest level in terms of atomic structure.
How can I memorize chemistry?
For example, a mnemonic to memorize the first elements of the periodic table is “Hi, he lies because boys can not operate fireplaces.” This translates into hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine. You could choose other words to stand for the letters.
