If an element has three isotopes with known masses what information is needed to find the average atomic mass of the element?
The abundance percentage of each isotope
If an element has 3 isotopes with known masses what other information is needed to find the average atomic mass of the element?
You would also need to know the abundance of each of the isotopes, i.e., how much percent of each you will typically encounter.
What is the atomic number of As?
if you look @ the Periodic Table, you will find the tiny # above the element... that is its atomic #.
How do you find out the atomic number of an element?
Atomic number is the no. of protons or no. of electrons in an atom .
How do you find the number of nucleons?
To find the number of neutrons in an atom, first find the atomic weight of the element and round that number to the nearest whole number. Then, find the atomic number of the element. Subtract that number from the atomic weight and the number of neutrons will be found.

If an element has 3 isotopes with known natural abundance percentages what other information is needed to find the average atomic mass of the element?
You still need to know the number of protons present in order to find the atomic mass.
What is the difference between average atomic mass and atomic mass?
Why is the atomic mass an average?
Because there can be many different forms of that element. So they they find the mass of all the forms of that element and make is an average.

You would also need to know the abundance of each of the isotopes, i.e., how much percent of each you will typically encounter.
How is average atomic mass determined from isotopic masses?
The atomic mass that you see on the periodic table is an average mass taken from all of the element's known isotopes. Simply find the average of all of the masses of the isotopes of an element.
What are the steps in the process of calculating average in atomic mass given data about the isotopes of an element?
I can't find it
What is the average atomic mass of tungsten?
If you look on a periodic table under the element tungsten which is represented as W, you will find the atomic mass on the top right side. It's average weight is 183.84 and the atomic number of 74
What is the atomic number of atoms?
how do you find the atomic number for an element?
What is atomic number and where can you find an element's atomic number?
The atomic number is the number of protons in the element. For example calcium has 20 protons, so that means it has an atomic number of 20. You can find the element's number on the periodic table; its usually the number on top of the element's symbol
What is an atomic number and where can you find one listed?
the atomic number is the number of protons of an element. The atomic number specifically identifies an element. You can find it on the Periodic Table of Elements.
