Below is a representation of 50 atoms of a fictitious element called varsenum(Va
Va). The red spheres represent Va
Va-142, the blue spheres Va
Va-143, and the green spheres Va
Va-144
Assuming that the sample is statistically representative of a naturally occurring sample, which isotope has the highest isotopic abundance?
Enter the symbol of the element followed by a hyphen and the mass number (e.g., U-234).
The atomic mass of the element would be closer to the mass of which isotope?
Enter the symbol of the element followed by a hyphen and the mass number (e.g., U-234).
Va-142
Step-by-step explanation
Va-142 has the highest abundance because red colored Balls are more than others and Atomic mass also would be closer to this.
