Hint: We know that calcium is a compound symbol \[Ca\] and nuclear number \[20\]. As a basic earth metal, calcium is a receptive metal that shapes a dim oxide-nitride layer when presented to air. Its physical and compound properties are generally like its heavier homologues strontium and barium.
Complete answer:
We must have to remember that both Magnesium and Calcium have a place with a similar group (II) and are fit for losing electrons which are liable for their reactivity. Magnesium lies above Calcium in Group II. As we drop down a gathering, the powerful atomic charge on valence shell electrons diminishes because of which losing electrons become simpler. Hence Calcium is more receptive than Magnesium.
Additional information:
We have to know that the science of calcium is that of a normal substantial basic earth metal. For instance, calcium unexpectedly responds with water more rapidly than magnesium and less rapidly than strontium to deliver calcium hydroxide and hydrogen gas. It likewise responds with the oxygen and nitrogen noticeable all around to shape a combination of calcium oxide and calcium nitride. When finely isolated, it suddenly consumes in air to deliver the nitride. In mass, calcium is less receptive: it rapidly shapes a hydration covering in soggy air, however underneath \[30\% \] relative stickiness it very well might be put away inconclusively at room temperature.
Note:
We must have to remember that the calcium, strontium, barium, and radium are constantly viewed as antacid earth metals; the lighter beryllium and magnesium, additionally in group \[2\] of the table, are frequently included also. By and by, beryllium and magnesium vary altogether from different individuals from the gathering in their physical and compound conduct: they act more like aluminum and zinc separately and have a portion of the more fragile metallic character of the post-change metals, which is the reason the conventional meaning of the expression "antacid earth metal" bars them. This characterization is for the most part out of date in English-language sources, yet is as yet utilized in different nations, for example, Japan. Therefore, examinations with strontium and barium are more pertinent to calcium science than correlations with magnesium.
