How are atomic mass and atomic number different?

Atomic number is the number of protons in the nuclei of the atoms of an element. Atomic number is unique to each element. Atomic Mass is the combined mass of the protons, neutrons, and electrons in an atom of an element.


What elements have the atomic number 12 and atomic mass 8?

There is no element with an atomic number of 12 and an atomic mass of 8. Atomic number corresponds to the number of protons in an atom, while atomic mass is the sum of protons and neutrons. The atomic number of an element cannot be smaller than its 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.

Distinguish between the atomic number and mass number of an element?

The atomic number of an element is the number of protons in the nucleus of each atom of the element. Mass number is a property of a particular isotope of the element rather than of the element itself: The mass number is the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope.

How do you calculate neutrons for elements in the periodic table?

them mass number of an element is the total amount of nuetrons and protons in the element , and the atomic number is the amount of protons ( and electrons) in the element simply subtract the atomic number from the mass number and you'll have the number of neutrons in the element hope this helped x
