When the masses of all naturally occurring isotopes of a particular element are averaged the result is called the element's .?
If the masses of the individual isotopes are on the scale where one atom of the isotope carbon-12 has a mass of 12 units, then the weighted average of the masses of all isotopes present in a natural sample of an element is called its relative Atomic Mass, r.a.m.

What is the average mass of an isotope?
You must specify the element whose isotopes you want the weighted average mass for. Otherwise there is no answer as just averaging the masses of isotopes without accounting for how much of each isotope is present in a sample of an element is meaningless. Also averaging masses of isotopes of different elements is also meaningless.
Why is atomic mass not a constant number?
The atomic mass is the average of all of the different isotopes of the element present in the sample. Samles taken from aound the worlld for some elements have slightly different isotope ratios and therefore have different atomic masses.
Why is there an average atomic mass?
There is an average atomic mass because all atoms of the same element do not have the same amount of neutrons (isotopes), therefore variations in atomic mass exist. The average atomic mass of an element is the estimated average of all the atoms of the same element, given the average of different isotopes in a scientific sample.
The time it takes for half of the radioactive element to decay is the element's what?
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
How is the mass number of an isotope different from the average atomic mass that is on the periodic table?
The mass number for a particular isotope of an element is a precise value. The average atomic mass for an element is the value you would measure for that element given all the isotopes it has and their abundance in the sample.
As a sample of a radioactive element decays its half-life?
No, the half life remains exactly the same throughout
How long will it take half of a radioactive sample to decay?
The length of time depends on the element and isotope, but the point at which half of the sample has decayed is known as the half-life.
How many different masses of the Cl2 molecule would you expect to find in a sample of chlorine gas?
three different masses.
What is the macroscopic sample element of zinc?
The chemical symbol of zinc is Zn; "macroscopic sample element" is a strange formulation in chemistry.
The color of light given off when a sample is heated corresponds to?
heated of the element heat absorbed by the sample amount of energy added to the sample energy difference between the ground state and exited states of an element.
