The type of element an atom belongs to is determined by the number of protons in the nucleus. Iron, for example, always has 26 protons. The number of neutrons can vary. In naturally occurring iron there are four stable isotopes iron-54 (5.82 percent) 28 neutrons iron-56 (91.66 percent) 30 neutrons iron-57 (2.19 percent) 31 neutrons iron-58 (0.33 percent) 32 neutrons When doing calculations it is assumed the iron is close to this mixture and so the Atomic Mass will be calculated as the average weight of an iron atom.

What is kryptons average atomic mass number?
The Atomic Mass of krypton is 83.80(1) if you round 84
Weighted average atomic mass?
What is weighted average atomic number
What is the average atomic mass compared to the atomic mass?
Atomic Mass is the number of protons and neutrons in an atom.
How is the mass number different from the average atomic mass?
The mass number is the total number of protons and neutrons in an atom's nucleus, while the average atomic mass is the weighted average of the masses of all isotopes of an element based on their abundance in nature. The mass number is a whole number, while the atomic mass is a decimal value.
What is the difference between the atomic number and average atomic mass?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Which is the average of the mass number of an element isotpes?
The atomic weight or atomic mass.
What is the atomic mass number of 28.09?
The atomic mass number of an element is the sum of the number of protons and neutrons in its nucleus. To get the atomic mass number of 28.09, it typically corresponds to the average atomic mass of an element on the periodic table. For example, the element silicon has an average atomic mass of approximately 28.09, indicating that a silicon atom has an atomic mass number of around 28.
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 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 difference between mass number relative atomic mass and average atomic mass?
The mass number is the total number of protons and neutrons in an atom's nucleus. Relative atomic mass is the weighted average mass of all the isotopes of an element, taking into account their natural abundance. Average atomic mass is the weighted average mass of an element's isotopes in a given sample, considering their abundance in that sample.
Atomic mass differnet from the atomic mass number why is that?
The atomic mass is an average, allowing for the relative abundances of different isotopes.
What does a mass number determine?
mass number = number of protons + number of neutrons DIFFERENT FROM ATOMIC MASS atomic mass = weighted average of all the isotopes of that element
