{'superphosphate': [0, 0, 1, 0], 'magnesium': [1, 0, 2, 3], 'metal atom': [0, 0, 1, 0], 'potassium': [1, 0, 0, 2], 'sodium': [10, 2, 12, 23], 'calcium': [2, 0, 0, 4], 'mg': [1, 0, 4, 6], 'na': [0, 0, 2, 2]}

In superphosphate, the metal atom present is calcium (Ca). Superphosphate is a fertilizer that is commonly used in agriculture to provide plants with the essential nutrient phosphorus. It is produced by treating phosphate rock with sulfuric acid to break it down and make it more soluble.

The metal atom present in superphosphate is calcium. This means that the compound contains calcium ions (Ca2+), which are important for plant growth and development. Calcium is a macronutrient that is required by plants in relatively large quantities. It plays a crucial role in cell wall development, enzyme activation, and various metabolic processes.

Options 1, 2, and 4 (sodium, potassium, and magnesium) are not the correct metal atoms present in superphosphate. Sodium and potassium are both alkali metals and are not typically found in superphosphate. Magnesium, on the other hand, is an alkaline earth metal and is not the metal atom present in this compound.

Therefore, the correct answer is option 3: calcium (Ca).
