Following the series K+,Na+,Ca2+,Mg2+,Al3+,Zn2+,Fe2+,Sn2+,Pb2+,H+........ And so on,we can observe that their electropositivity decreases down the series. That means that K+ is more electropositive than Na+,which is now electropositive than Ca2+ and so on.that is why sodium can be displaced from a solution of its salt by potassium,while calcium can be displaced out of a solution of its salt by sodium and so on.
Let's break down the electrochemical series! It's like a list of elements (mostly metals) arranged in order of how easily they lose or gain electrons.
* Electropositivity means how easily a metal loses electrons to become a positive ion.
* Electronegativity means how strongly a non-metal attracts electrons to become a negative ion.
Now, let's look at your options:
* A. Electropositivity of metals increase down the series: This is incorrect. The most electropositive metals are at the top, meaning they lose electrons most easily.
* B. Electropositivity of non-metals decrease down the series: Non-metals are not really the focus of the electrochemical series, it focuses more on metals, and how easily they lose electrons.
* C. Electronegativity of non-metals decrease down the series: While electronegativity is important, the electrochemical series is primarily about how metals lose electrons, not how non-metals gain them.
* D. Electropositivity of metals decreases down the series: This is correct! As you go down the electrochemical series, metals become less likely to lose electrons.
So, the correct answer is D. Electropositivity of metals decreases down the series.
this just doesnt sit right, imagine.. are you trying to say electropositivity and negativity of non metals both increase down the group??? of course not.
the question has an error.
there should be 2 electronegativity and 2 electropositivity choice of options there, instead we have 3:1
makes 2 options correct.
pls there is difference between electroch..and activity series...option a is d best
c is correct...i av a formula called PAREN...It means atomic radius and electronegativity increace across d P-period and decreaces down d group...so opt c is ryt.
