well you look at the periodic table of elements. the atomic number equals the number of protons. Then subtract the number of protons from the atomic mass (both protons and nuetrons have atomic mass units of 1 and electrons equal 0). That will give you the number of nuetrons.
An atom with 8 protons will have an atomic number of 8. Checking the periodic table, we see this element is oxygen. The isotope of oxygen with 8 neutrons is 16O.
The atomic number on the periodic table is the number of protons for the element.
It is the Element Tin
The element with 50 protons on the periodic table is tin, which has the atomic number 50.
The atomic number tells us the number of protons in the nucleus of an atom. It determines the element's identity and its place on the periodic table. Elements with different atomic numbers have different chemical properties.
The number of protons is the atomic number of the element.
