Question

Suppose a new element with atomic number 120 is discovered.If some isotopes of this element have 122 neutrons and some have 124 neutrons,what can you infer about the atomic mass of the element?Explain you answer.

Answer 1

Answer:

I assume you are referring to the standard atomic weight of the elements when you write atomic mass. No elements beyond uranium has a standard atomic weight. The reason is explained by the organization assigned responsibility for the assignment of standard atomic weights,the international Union of Pure and Applied Chemistry commission on isotopic abundances and atomic weights.
