Please the order of reactivity of metals is determined by the electrochemical series not oxidation number. The electrochemical series lists metals in decreasing order of areactivity. The Reactivity of a metal is a measure of how easily oxidised it is, which means that the most easily oxidised metals will be higher in position than the least oxidised metals. So here is the series
K - Potassium
Na - Sodium
Ca - Calcium
Mg - Magnesium
Al - Aluminium
Zn - Zinc
Fe - Iron
Sn - Tin
Pb - Lead
Cu - Copper
Hg - Mercury
Ag - Silver
Au - Gold
Out of all the options, Zinc is the lowest in the series, which means it the least reactive and least easily oxidised
Please-potasium
Sir-sodium
Call-calcium
Me-magnesium
Alumni-aluminium
Zin-zinc
Is-iron
The-tin
Leader-lead
Here-hydrogen
Cobblers-copper
Make-mercury
Slippers-silver
Good-gold...
Lollss..just formed it for u guyz
I don't know maybe the easiest way is;
Please (Potassium K+)
Stop (sodium Na+)
Calling (calcium Ca2+)
Me(Magnesium Mg2+)
A(Aluminium Al 3+)
Careless(Carbon C)
Zebra(Zinc Zn2+)
Instead (Iron Fe2+)
Try(Tin Sn2+)
Learning (Lead Pb2+)
How(Hydrogen H+)
Copper(Cu2+)
Save(Silver Ag)
Gold(Au 2+)
I guess this should do the thing 👀
Plz guys d ans is vry correct.NB= d questn said least easily oxidized.analyzn d questn,Na is most easily oxidized wit oxidatn number of +1, followed by Ca nd Zn wit +2 before Al wit +3.xo d ryt ans is Al.Take it 2 Rome.
The fact that Zinc is below Aluminum in the electrochemical series makes Zinc through correct answer
metallic oxides of metals depends on the position of the metal in the electrochemical series.
GUYS I THINK THE OXIDISED HERE IS REFERING TO INCREASE IN OXIDATION STATE.ALUMINIUM HAS THREE ELECTRONS IN THE OUTERMOST SHELL AND IS CLOSER TO THE NUCLEUS THIS WILL LEAD TO A HIGH ATTRACTIVE FORCE OF THE NUCLEUS ON THE ELECTRON IN THE OUTERMOST SHELL THEREBY REQUIRING A HIGH IONIZATION ENERGY TO OXIDIZE IT(REMOVE ELECTRON FROM IT).
According to the table of activity series of metal and from the option zinc is the least oxidized and not aluminum
The answer is zinc. The order of some common metals in the electromotive series, starting with the most easily oxidized, is: lithium, potassium , calcium, sodium, magnesium , aluminum , zinc , chromium, iron, cobalt, nickel, lead, hydrogen, copper, mercury, silver, platinum, and gold.
The ans is zinc. Everybody should know that. K-potassium
N-sodium
C-calcium
M-magnesium
A-aluminium
Z-zinc
F-iron
S-tin
P-lead
H-hydrogen
C-copper
H-mecury
A-silver
A-gold
Electropositivity decreases down the series as well as the ease to oxidize. Zinc is the ans since it comes after aluminium
sodium(Na)....( 1)
calcium(ca).....( 2)
zinc(zn)............( 2)
Aluminium(Al)..( 3)
so...when the oxidation state increase, it will be easily to oxidize and the oxidation state of Al is the highest...so, it will be easily oxidized
sodium(Na)....( 1)
calcium(ca).....( 2)
zinc(zn)............( 2)
Aluminium(Al)..( 3)
so...when the oxidation state increase, it will be easily to oxidize and the oxidation state of Al is the highest...so, it will be easily oxidized
