Henry Moseley
What else can I help you with?
Is a chart that displays all elements by atomic numbers and can be used to determine the number of valence electron for some elements?
the periodic table
How do people use uranium rays?
Uranium has many applications but the use of emitted rays is not important.Uranium is used as nuclear fuel or for atomic bombs.
What are atomic numbers used for?
It is to define the elements according to their groups.
Is a pair of numbers used to determine the position of a point on a graph?
On a 2-D graph, a pair of numbers are used to determine the position of the point on a graph.
What did British scientist Henry Moseley determine?
British scientist Henry Moseley determined the concept of atomic number as the basis for the modern periodic table, demonstrating that it is a more fundamental property of an element than its atomic mass. He also used X-ray spectroscopy to accurately determine the atomic numbers of elements, which led to a more organized and predictive arrangement of the elements in the periodic table.
How is a atomic number determined?
Atomic number of any element is determined by its X-ray diffraction. Since, X-rays have very high penetrating power, they are used for such purposes. The X-ray diffraction provides idea about the composition of an atom and hence scientists are able to determine the properties of the element.

Can Atomic mass be used to determine molecular mass?
Yes, the accumulation of atomic masses of the atoms within a molecule is the molecule's molecular mass.
What is the set of numbers that is used to identify the element?
The atomic number generally. the atomic number is the number of protons(or electrons) an atom has.
Is it true that the mass number can be used to determine the number of electrons in an atom?
no --- atomic number
What atomic number is 47 used to make photographic film?
The element with atomic number 47 is Silver (Ag). It is used in photographic film, as well as solar panels, water filtration, X-rays, and disinfectants.
What is the device used to determine atomic masses?
A mass spectrometer is a device used to determine atomic masses by separating and measuring the mass-to-charge ratio of ions. By analyzing the deflection of ions in a magnetic or electric field, the mass spectrometer can provide accurate measurements of atomic masses.
