Question

_________ is a value that depends on the distribution of an element's isotopes in nature and the masses of those isotopes.

a) Atomic number
b) Atomic radius
c) Atomic structure
d) Atomic weight

Answer 1

The atomic weight is a value that depends on the distribution of an element's isotopes in nature and the masses of those isotopes. It is calculated as the weighted average of the masses of all the element's naturally occurring isotopes.

Step-by-step explanation:

The value that depends on the distribution of an element's isotopes in nature and the masses of those isotopes is the Atomic weight. The atomic weight is the weighted average of the masses of all the element's naturally occurring isotopes. It is calculated by multiplying the mass of each isotope by its relative abundance and summing them up.
