There is no average atomic number. The atomic number of an element is the number of protons in the nuclei of its atoms. It is a whole and finite number. The elements are arranged in order of increasing atomic number on the Periodic Table.

Atomic number of germanium?
Atomic No.: 32 Average Atomic Mass: 72.64
How would the modern periodic table would be different if elements were arranged by average atomic mass instead of by atomic number?

What does the number below each symbol represent?
The average Atomic Mass
How do you find the protons and electrons?
To find the number of protons, you use the atomic number. The atomic number is always the same number of protons. To find the average number of neutrons, you use the atomic mass and take away the number of protons. For example Oxygen has an atomic number of 8 and an atomic mass of 16.01, so since it has an atomic number of 8, it always has 8 protons, and since oxygen has a mass of 16.01, it has an average of 8.01 neutrons (the math: 16.01 mass-8 protons=8.01 neutrons). If your dealing with isotopes, you round the mass number. The mainest isotope is 8 neutrons in oxygen, but there is a few oxygen atoms that have 9 neutrons which is why the average mass is little higher than 16.
What does the number 24.305 represent for magnesium?
That is the average atomic mass for Mg.
Weighted average atomic mass?
What is weighted average atomic number
How do you calculate average atomic number of an element?
There is no average atomic number. The atomic number of an element is the number of protons in the nuclei of its atoms. It is a whole and finite number. The elements are arranged in order of increasing atomic number on the periodic table.
Atomic number of germanium?
Atomic No.: 32 Average Atomic Mass: 72.64
What is kryptons average atomic mass number?
The average atomic mass number of Krypton is approximately 83.8 atomic mass units.
What is the difference between average atomic mass and atomic mass?
How do you use atomic number and average atomic mass to calculate the number of each of the three subatomic particles?
The atomic number is the amount of protons which will equal the amount of electrons. The average atomic mass minus the number of protons will equal the amount of neutrons.
How many protons and neutrons are in the nucleus of the atom?
No it is not the atomic number. We call it mass number.
What is the average atomic mass compared to atomic mass?
Atomic mass is the number of protons and neutrons in an atom.
What is the average atomic number of lithium?
the atomic no.of lithium is 3
Is the atomic number and the atomic weight the same?
No, the atomic number is the number of protons and electrons in a given element. The atomic weight is the weighted average of the isotopes in a natural environment.
What does an atomic mass number consist of?
The atomic mass consists of the number of protons plus the number of average neutrons.
What is the isotope number used for on the periodic table?
There is not an isotope number on the Periodic Table of Elements. There is an atomic number (# of protons) and the average atomic mass. The average atomic mass is the weighted average of all the naturally occurring isotopes for each element. This number is not a whole number, because it is an average of all the isotopes for a particular element.
