Which element does X represent in the following expression superscript41 and subscrit 20X?
Updated: 12/1/2025
In the expression ( ^{41}{20}X ), the element represented by X is calcium (Ca). The superscript 41 indicates the mass number (the total number of protons and neutrons), while the subscript 20 indicates the atomic number (the number of protons), which corresponds to calcium on the Periodic Table. Thus, ( ^{41}{20}Ca ) represents a specific isotope of calcium.
