How is the atomic weight of an element found?
you add the number of protons (the atomic number) to the number of neutrons
How is the number of neutrons in an atom found?
The number of neutrons in an atom can be found by subtracting the number of protons (which is the atomic number) from the mass number. The mass number is the sum of protons and neutrons in the nucleus of an atom.
What is the atomic number and what does the atomic number indicate?
Atomic number is the number of protons in the nucleus of an atom. The periodic table is arranged in an order of increasing atomic numbers.
Which element has lowest atomic number and is not found in nature?
Hydrogen has the lowest atomic number, and is not found in nature as individual atoms, but is found in nature as the diatomic molecule, H2.
Who found a relationship between the wavelengths of x-rays and the atomic number of elements?
Henry Moseley found the relationship between the wavelengths of x-rays and the atomic number of elements. He proposed that the atomic number of an element is better defined by the number of protons in the nucleus rather than by its atomic mass.

How atomic number is related to proton number?
The atomic number is the number of protons found in the nucleus of an atom.
How is the atomic weight of an element found?

The number of neutrons in an atom can be found by subtracting the atomic number from the?
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.
How is the number of neutrons in an atom found?
The number of neutrons in an atom can be found by subtracting the number of protons (which is the atomic number) from the mass number. The mass number is the sum of protons and neutrons in the nucleus of an atom.

Which element has lowest atomic number and is not found in nature?
Hydrogen has the lowest atomic number, and is not found in nature as individual atoms, but is found in nature as the diatomic molecule, H2.
Can atomic number be found on the periodic table?
The atomic number is the number located in the upper left corner of the element on the periodic table. Elements are listed in order of increasing atomic number.
What is the atomic number of argon?
The atomic number of argon is 18. It is a noble gas with the symbol Ar and is found in group 18 of the periodic table.
