How many protons in lithium 7
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. WebAnswer (1 of 3): Hey, are you the same person who wants to know who is buried in Grant’s Tomb? “Mass number” refers to the total of protons + neutrons in the nucleus of an atom. The way to refer to a specific isotope, with a set number of protons and neutrons, is by following the name of the ele...
