How many protons in lithium 7
WebWij willen hier een beschrijving geven, maar de site die u nu bekijkt staat dit niet toe. WebThe number of neutrons in an element is obtained from the difference between the number of atomic masses and the number of atoms. That is, neutron number (n) = atomic mass number (A) – atomic number (Z) We know that the atomic number of lithium is 3 and the atomic mass number is about 7 (6.938). Neutron (n) = 7 – 3 = 4.
How many protons in lithium 7
Did you know?
WebSo A is the mass number, which is equal to the number of protons, that's the atomic number which we symbolized by Z, plus the number of neutrons. So A is equal to Z plus N. And for protium, let's look at protium here. So in the nucleus there's only one proton and zero neutrons, so one plus zero gives us a mass number of one. WebBuild an Atom - PhET
