### What is the weighted average of the atomic masses of an element's naturally occurring isotopes is called the?

The atomic weight that is listed on the periodic table for each element is the weighted average of the atomic masses of an element's naturally occurring isotopes. So you are describing atomic weight as it is used on the periodic table.

### The atomic mass of an element is defined as the weighted average mass of that element's?

For the chemical elements the correct expression is atomic weight.This value is the weighted average mass of the natural isotopes of this element.

### What is the weighted average of the masses of all naturally occurring isotopes of an element?

The atomic weight of the element (syn.: mass number).

### What is the average of all the naturally occurring isotopes of a particular element?

The average of all the naturally occurring isotopes of a particular element are an element's atomic Mass.

### Which statement best explains why most atomic masses on the periodric table are decimal numbers?

Atomic masses are a weighted average of the naturally occurring isotopes.

### What element has the neutron number of 30.69?

This is the weighted average neutron number for the naturally occurring isotopes of nickel, which has the atomic number 28 and the gram-atomic mass of 58.69. In an individual isotope, the neutron number is always the isotopic atomic mass number minus the atomic number, and the same principle applies to the weighted average neutron number for the naturally occurring isotopes of an element.

### What is the average atomic mass compared to atomic mass?

Atomic mass is the number of protons and neutrons in an atom.

### When the masses of all naturally occurring isotopes of a particular element are averaged the result is called an elements what?

The weighted average of all of the natural occuring isotopes for a particular element is called its Atomic Weight (or Relative Atomic Mass)
