Atomic masses are determined by mass spectrometry. The atomic number is identic with the number of protons in the atom - depends on position in the Periodic Table.
Every elements has atomic number, elements identity determined the number of protons in its nucleus.
You think probable to atomic number, equal to the number of protons in the atomic nucleus.
increasing atomic number and repeating properties
by atomic number
Elements are arranged in a periodic table by atomic number, lower on top and left. Atomic masses have no direct relationship to the arrangement of atoms, although generally atoms with higher atomic numbers will have higher atomic masses. (There are at least three exceptions for atoms with atomic numbers differing by 1.)
Why are atomic masses of elements not generally whole numbers? The atomic masses listed on the periodic table are a weighted AVERAGE of an element'sisotopes. ... An element's atomic number is the number of protons in its nucleus. Number of protons specifies atom type.
Number of protons in the nucleus (=atomic number)
He determined the number of protons of the elements, which is called the atomic number.
the properties of elements are determined by the structures of their atoms.
Different atoms and elements that have different number of protns, neutrons and electrons.Duh!
Since you have isotopes of elements. Isotopes are elements with different number of neutrons hence why the different atomic masses for the same elements.
Yes, it is the atomic number i.e. number of protons that determines an element's identity.
