Which of the following will be more reactive than magnesium ()

Potassium(K) is the most reactive element than magnesium.

Explanation:

K is more reactive.

Explanation:

We follow the reactivity series to say which one is more reactive than the other.

Oxidation is loss of electrons by an atom or a species.

The element which gets oxidised easily is more reactive than the one which is less oxidised.

Zn undergoes more easily than Copper. Thus we say Zinc is more reactive than Copper.

Zinc is more reactive than copper thus it replaces copper in this reaction.

Copper cannot replace Zinc as it is less reactive. Thus No reaction occurs when Copper reacts with Zinc sulphate

We can observe this in the reactivity series or electrochemical series which is as follows

more reactive ……………………………………………………………………………….

…………………………………………………………………………………..least reactive

So, The Answer will be K and Ca.

Moving down a group, the reactivity decreases.

Hence we can say that K is more reactive than Mg.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
