Calcium is more reactive than magnesium.
Barium would be more reactive than magnesium because it is located lower in the alkali earth metal group on the Periodic Table. Elements located lower in a group tend to have more reactive properties because of their larger atomic radius and lower ionization energy.
Do you ever remember having seen calcium metal in the open? Magnesium alloys are seen much more frequently on car wheels, etc. That suggests that calcium by nature is more reactive than Magnesium.
Why is that so? Because the atomic number of calcium (20) is higher than the atomic number of Magnesium (12). The atomic number is also the number of electrons and since calcium has a higher number of electrons, it has a higher atomic radius (197 pm) compared to the atomic radius of Magnesium (160 pm).
Since the outlying electrons in a calcium atom is further away from the nucleus than Magnesium, it also becomes easy for this electron to drift away and react with other elements, thus giving in to the higher reactive nature compared to Magnesium.
In the group 2 elements, the reactivity of the metals increase as you move down the group. The order of reactivity in group 2 is barium, strontium, calcium, and magnesium.

Which is more reactive barium magnesium or beryllium?
Barium is more reactive than magnesium, and beryllium is less reactive than both. Reactivity generally increases as you move down a group on the periodic table, so barium is more reactive than magnesium due to its position in the same group.
Is silver more reactive then magnesium?
No, magnesium is more reactive than silver. Magnesium reacts readily with oxygen to form magnesium oxide, whereas silver is relatively unreactive.
Would magnesium and iron nitrate react?
Yes, magnesium and iron nitrate would not react under normal conditions because magnesium is less reactive than iron, and iron nitrate is typically stable and not easily reduced by magnesium.
Is iron more reactive than magnesium?
No, magnesium is more reactive than iron. Magnesium reacts more readily with oxygen and water compared to iron, forming magnesium oxide and magnesium hydroxide respectively.
Which element would be most reactive be sr or ba?
Barium (Ba) would be more reactive than strontium (Sr) because barium is located further down the Group 2 elements in the periodic table. As you move down the Group, the reactivity of the elements tends to increase due to the larger atomic size and lower ionization energy, making barium more reactive than strontium.
Which is more reactive barium magnesium or beryllium?
Barium is more reactive than magnesium, and beryllium is less reactive than both. Reactivity generally increases as you move down a group on the periodic table, so barium is more reactive than magnesium due to its position in the same group.
When evaluating reactants BaO plus Mg one needs to determine if magnesium is more active?
Barium is more reactive than magnesium.
Which is more reactive barium or cesium?
Cesium is more reactive than barium. Cesium is located lower down in Group 1 of the periodic table, making it more reactive than barium, which is further up the group. Cesium readily reacts with air and water, while barium is less reactive in comparison.
Element M reacts with chlorine to form a compound with the formula MCl2 It is more reactive than magnesium and smaller than barium This element is?
Element M is calcium. It reacts with chlorine to form calcium chloride (CaCl2). Calcium is more reactive than magnesium and smaller than barium on the periodic table.
Is magnesium more reactive than sodium?
sodium is more reactive than magnesium!
Is Sodium is more reactive than magnesium.?
sodium is more reactive than magnesium!
Is magnesium highly reactive or non reactive?
Magnesium is one of the more reactive metals; it rarely exists in nature elementally.
Is silver more reactive then magnesium?
No, magnesium is more reactive than silver. Magnesium reacts readily with oxygen to form magnesium oxide, whereas silver is relatively unreactive.
Which element is more reactive Mg or Ba?
Barium (Ba) is more reactive than magnesium (Mg) because as you move down a group on the periodic table, reactivity tends to increase. Barium is located below magnesium in Group 2 of the periodic table, which means it has an additional electron shell that is further away from the nucleus, making it easier to lose electrons and react.
Element M reacts with chlorine to for a compound MCl2 Element M is more reactive than magnesium and has a smaller radius than barium the element is?
Element M is likely calcium. It is more reactive than magnesium and has a smaller radius than barium, making it a good fit for the given properties. Calcium forms a compound MCl2 when reacting with chlorine.
Would magnesium and iron nitrate react?
Yes, magnesium and iron nitrate would not react under normal conditions because magnesium is less reactive than iron, and iron nitrate is typically stable and not easily reduced by magnesium.
Is iron more reactive than magnesium?
No, magnesium is more reactive than iron. Magnesium reacts more readily with oxygen and water compared to iron, forming magnesium oxide and magnesium hydroxide respectively.
