Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Mass number is the number of protons and neutrons in the nuclei of the atoms of a specific isotope of an element.
the Atomic Mass is found by adding up the masses of all the protons, nuetrons, and electrons of the atoms.
Every elements has atomic number, elements identity determined the number of protons in its nucleus.
No element has this atomic number. All atomic numbers are whole numbers.
The atomic number and number of protons are always the same in a normal element.
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.)
Atomic numbers are the number of protons and electrons in a atom.
The number of protons is the atomic number.
As atomic number rises so does the atomic mass. There is no close relationship. Atomic number is the number of protons in the nucleus. Average atomic mass takes the mass of naturally occurrring isotopes which include the mass of the varying numbers of neutrons present which account for a large proportion of the overall mass of an atom.
mass number=atomic number+no. of neutrons
The atomic number of a chemical element is identical to the number of protons.
Simply, the atomic number and the number of protons are the same. If the atomic number is 8, then there are 8 protons in the element.
The atomic number is the number of protons the element possesses.
The atomic number is equivalent to the number of protons; the number of neutrons is different for each isotope.
In 1914 Henry Moseley found a relationship between an element's X-ray wavelength and its atomic number (Z), and therefore rearranged the table by nuclear charge / atomic number rather than atomic weight. Before this discovery, atomic numbers were just sequential numbers based on an element's atomic weight. Moseley's discovery showed that atomic numbers had an experimentally measurable basis.
they describe the same thing. Proton numbers are unique to each element, as are atomic numbers
No relationship.
