1. Identify the elements: calcium (Ca), magnesium (Mg), sodium (Na), potassium (K), iron (Fe), zinc (Zn), copper (Cu), iodine (I), selenium (Se), chromium (Cr), manganese (Mn), molybdenum (Mo), fluoride (F), chloride (Cl), phosphorus (P), sulfur (S), cobalt (Co).
2. Classify each element as a major mineral or trace mineral based on daily requirement (major > 100 mg, trace < 100 mg).
3. Major minerals: calcium, magnesium, sodium, potassium, phosphorus, sulfur, chloride.
4. Trace minerals: iron, zinc, copper, iodine, selenium, chromium, manganese, molybdenum, fluoride, cobalt.
5. Place each element in the correct column of the table: “Major Minerals” or “Trace Minerals”.
6. Verify that all 17 elements are placed and none are missing.
7. Ensure no element is listed in both columns.
8. Double-check classification against standard nutritional guidelines.
9. Complete the table by writing each element’s symbol in the appropriate cell.
10. Review for accuracy and neatness before submission.
