No, sodium and calcium are not metalloids; they are both classified as metals. Sodium is an alkali metal, while calcium is an alkaline earth metal. Metalloids, on the other hand, have properties that are intermediate between metals and nonmetals, with elements like silicon and germanium being typical examples.
Sodium is a metal, having atomic number 11.
No. Sodium and calcium, both being metals, will not combine chemically. Table salt is a compound of sodium and chlorine.
When calcium reacts with sodium carbonate, calcium carbonate and sodium bicarbonate are formed. This reaction is a double displacement reaction where the cations and anions switch partners. Calcium carbonate is insoluble and precipitates out of the solution, while sodium bicarbonate remains dissolved.
Calcium ascorbate and sodium ascorbate are both forms of ascorbic acid (vitamin C) combined with a mineral. However, they are not the same; calcium ascorbate contains calcium, while sodium ascorbate contains sodium. Both are used as dietary supplements and have similar benefits, but their mineral content may affect their absorption and the choice for individuals with specific dietary needs or restrictions.
B statement is correct.
Sodium and calcium are metals, while chromium is a metal.

Calcium carbonate is insoluble and precipitates out of the solution, while sodium bicarbonate remains dissolved.
Both sodium and calcium can occur with a variety of other metallic elements or silicon. Perhaps you would like to review the wikipedia article about feldspar.
The element found in both lime and lye is calcium. Lime is calcium oxide (CaO) and lye is sodium hydroxide (NaOH), which can be produced from the reaction of calcium hydroxide (Ca(OH)2) with sodium carbonate.
Heparin sodium and heparin calcium are both types of heparin, but they differ in terms of the counter ions they are bound to. Heparin sodium has a sodium ion as a counter ion, while heparin calcium has a calcium ion. This difference can affect the dosage and administration of the medication.
Calcium ascorbate and sodium ascorbate are both forms of ascorbic acid (vitamin C) combined with a mineral. However, they are not the same; calcium ascorbate contains calcium, while sodium ascorbate contains sodium. Both are used as dietary supplements and have similar benefits, but their mineral content may affect their absorption and the choice for individuals with specific dietary needs or restrictions.
B statement is correct.
Sodium bicarbonate (NaHCO3) is soluble in water; calcium carbonate (CaCO3) is practically insoluble in water.
Elements ending in -ium are metals. Sodium and Calcium are alkali metals.
The reactions of sodium hydroxide and calcium hydroxide with sulfuric acid will produce sodium sulfate and calcium sulfate respectively (water will be another product in both reactions. Sodium sulfate is soluble in water and so will remain in solution. Calcium sulfate, however, is insoluble and will precipitate as a solid.
