Calcium is more reactive. In the Periodic Table, Calcium is directly below Magnesium, which means that a calcium atom is larger than a magnesium atom. This means that the electrostatic attraction between the valence electrons of calcium and the nucleus is weaker than in magnesium(larger distance, smaller force). So, the valence electrons of calcium can easily be lost to form Ca2+ , which translates to Calcium being the more reactive metal.

Is k or mg more reactive?
Potassium (K) is more reactive than magnesium (Mg) because potassium is a more reactive metal due to its lower position in the reactivity series. Potassium reacts more violently with water and air compared to magnesium.
Is au more reactive then mg?
Yes, gold (Au) is less reactive than magnesium (Mg). Magnesium is more reactive because it readily loses electrons to form positive ions, while gold is relatively unreactive.
Which metal is more reactive Mg or Al?
Magnesium (Mg) is more reactive than aluminum (Al) because it is higher up in the reactivity series of metals. This means that magnesium can easily lose electrons to form positive ions in chemical reactions compared to aluminum.
How does the reactivity of the elements in group 2 change on descending the group?
As you go down the Group 2 (alkaline earth elements) elements they become more and more reactive. i.e. H2O+Ca=Ca(OH)2+H2 there is more hydrogen (g) created and at a faster pace than H2O+Mg=Mg(OH)2+H2.
Why is Mg more reactive than Zn?
Mg is more reactive than Zn because Mg has a lower electronegativity than Zn, meaning it is more likely to lose electrons in a reaction. Additionally, Mg has a smaller atomic radius, allowing it to react more readily due to stronger electron-nucleus interactions.
What kind of reaction is this Mg plus 2AgCl 2Ag plus MgCl2?
Calcium(Ca), being a more reactive element, reacts with FeCl3 to produce CaCl2 and Iron(Fe).3 Ca + 2 FeCl3 ----> 3 CaCl2 + 2Fe
Who is more active Mg or Ca?
Ca is more active because it has an atom that is large. The larger the distance the smaller the force. If you want more information you should visit Which_is_more_reactive_Mg_or_Ca_Why
Is Ca or Sc more reactive in science?
Calcium (Ca) is more reactive than scandium (Sc) in science. This is because calcium is a more electropositive element compared to scandium, making it more likely to undergo chemical reactions with other elements.
What in a single displacement reaction?
A more reactive metal pushes out a less reactive metal out of a compound element, eg. CuSo4+Mg=MgSo4+Cu
What is the equation balance and identify the type of reaction of Ca Mg(NO3)2?
The balanced equation for Ca + Mg(NO3)2 would be Ca + Mg(NO3)2 -> Ca(NO3)2 + Mg. This is a double displacement reaction, where the calcium (Ca) and magnesium (Mg) ions switch places with the nitrate ions (NO3).
Which is more basis Ca or Mg?
If you mean which is more basic, Calcium would be because it is more electronegative.
What does Ca and Mg in science stand for?
In chemistry Ca stands for calcium and Mg stands for magnesium.
