In the expression "41 20 X," the numbers likely represent atomic numbers in the Periodic Table. Atomic number 41 corresponds to niobium (Nb), and atomic number 20 corresponds to calcium (Ca). Therefore, X would represent the element that comes after calcium, which is scandium (Sc) with an atomic number of 21.
What else can I help you with?
Which element does X represent in the following expression superscript41 and subscrit 20X?
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.
What is an expression that's equivalent to (84 plus 16)?
An expression equivalent to (84 plus 16) is 100. You can also represent it as 84 + 16, which simplifies directly to 100. Additionally, it can be expressed as 120 - 20 or 50 + 50.
What is a expression of 20X20?
