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.
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.
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.
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.
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.
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.
Calcium(Ca), being a more reactive element, reacts with FeCl3 to produce CaCl2 and Iron(Fe).3 Ca + 2 FeCl3 ----> 3 CaCl2 + 2Fe
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
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.
A more reactive metal pushes out a less reactive metal out of a compound element, eg. CuSo4+Mg=MgSo4+Cu
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).
If you mean which is more basic, Calcium would be because it is more electronegative.
In chemistry Ca stands for calcium and Mg stands for magnesium.
