Difference Between Atomic Number and Atomic Weight ...
4. Distinguish between the atomic number and atomic weight of an atom of an element. 5. Discuss how isotopes of atoms of a particular element differ. 6. Given the atomic number of an atom, you should be able to determine the following: a. the number of protons; b. the number of electrons; c. the electron configuration of the atom;

Neutron number (N) = number of neutrons for an element (can vary from the number of protons. This is called isotopes) The atomic mass (A) = Z+N, Q: why not consider the electron mass as well? A unit of mass for atoms is called an atomic mass unit (amu) = 1/12 of the Carbon 12 (12C) isotope which is the most common isotope of carbon. Here A=12 ...

The atomic number drops by two and it becomes the element, thorium, with an atomic number of 90. Beta Particle, : Has a –1 charge; comes from a neutron being given off – the neutron gives off a beta particle (negative) and a proton (positive); the beta particle leaves and the proton stays in the nucleus.
