Could two different elements have the same atomic number or the same mass number?

Question

Accepted Answer

∻Answer∻ ⚹ No, two different elements cannot have the same atomic number, but they can have the same mass number. ⚹ ∻Solution∻ ‖ a ⋮ Atomic number: The atomic number of an element is defined by the number of protons in its nucleus. Each element has a unique atomic number, which means no two different elements can have the same atomic number. ‖‖ b ⋮ Mass number: The mass number is the sum of protons and neutrons in the nucleus of an atom. Different elements can have the same mass number if they have different numbers of protons and neutrons that add up to the same total. For example, Carbon-14 ($^{14}C$) and Nitrogen-14 ($^{14}N$) both have a mass number of 14 but different atomic numbers (6 and 7, respectively). ‖ ∻Key Concept∻ ⚹ Atomic number and mass number ⚹ ∻Explanation∻ ⚹ The atomic number is unique to each element and defines the element, while the mass number can be the same for different elements if the sum of protons and neutrons is the same. ⚹◊Can two different elements have the same mass number⍭ Generate me a similar question◊
