Atomic Number • Hydrogen has one proton in the nucleus, and 1 electron around its nucleus. • Oxygen has eight protons in the nucleus, and eight electrons around its nucleus. Mass Number • Mass number is
Atomic number: number of protons in the nucleus of the atom. It defines the chemical properties of the atom. Atomic mass: mass of one mole of atoms, in grams, averaged over all stable isotopes. The atom mass of a pure isotope is equal to the number of protons and neutrons. The unit ...
The changing models of atomic structure over time and the use of evidence to accept or reject particular models. Atomic structure in terms of the numbers of protons, neutrons and electrons for atoms and ions, given the atomic number, mass number and any ionic charge....
