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.
What else can I help you with?
What are elements determined by number?
You think probable to atomic number, equal to the number of protons in the atomic nucleus.
How are the abbreviations on the periodic table of elements determined?
by atomic number
What Moseley determine in element?
Moseley determined that the number of protons in the nucleus of an atom corresponds to the element's atomic number. This discovery led to the modern periodic table where elements are arranged in increasing atomic number.
Why the atomic mass numbers listed for elements on the Periodic Table are not whole numbers.?
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.
How is the atomic mass determined?
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
How was the atomic number and the atomic mass determined?
The atomic number of an element is determined by the number of protons in the nucleus, which can be identified through methods like spectroscopy and X-ray diffraction. Atomic mass is determined by the total number of protons and neutrons in the nucleus, which can be calculated based on the element's isotopic composition and their respective masses.
The ordering of the elements in the periodic table is determined?
Number of protons in the nucleus (=atomic number)
How are the atomic numbers and the atomic masses of the elements related to how the elements are arranged on peridoic table?
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.)
What is the relationship between the atomic number and the elements identity?
The atomic number of an element determines its identity. Each element has a unique atomic number, which is the number of protons in the nucleus of its atoms. This number defines the element and distinguishes it from other elements on the periodic table.
What has different atomic masses?
Different atoms and elements that have different number of protns, neutrons and electrons.Duh!
No two elements will have the what atomic number?
No two elements will have the same atomic number because the atomic number of an element is determined by the number of protons in the nucleus of an atom. Since each element has a unique number of protons, each element will have a unique atomic number.
The atomic weight of an element is determined by what?
The atomic weight of an element is determined by the weighted average of the masses of its isotopes, taking into account their abundance in nature. This value is typically found on the periodic table as the average atomic mass of the element.
