Ba=137.33
Cl= 2(35.453)= 70.906
O= 8(15.9994)= 127.9952
then add all the masses together
Total Molar Mass= 336.2312
The principal quantum number, <span>nn</span>, designates the principal electron shell. Because n describes the most probable distance of the electrons from the nucleus, the larger the number n is, the farther the electron is from the nucleus, the larger the size of the orbital, and the larger the atom is. n can be any positive integer starting at 1, as <span><span>n=1</span><span>n=1</span></span> designates the first principal shell (the innermost shell). The first principal shell is also called the ground state, or lowest energy state. This explains why <span>nn</span> can not be 0 or any negative integer, because there exists no atoms with zero or a negative amount of energy levels/principal shells. When an electron is in an excited state or it gains energy, it may jump to the second principle shell, where <span><span>n=2</span><span>n=2</span></span>. This is called absorption because the electron is "absorbing" photons, or energy. Known as emission, electrons can also "emit" energy as they jump to lower principle shells, where n decreases by whole numbers. As the energy of the electron increases, so does the principal quantum number, e.g., n = 3 indicates the third principal shell, n = 4 indicates the fourth principal shell, and so on.
Geiger–Marsden experiment(s)<span> (also called the </span>Rutherford gold foil experiment<span>) were a landmark series of experiments by which scientists discovered that every </span>atom<span> contains a nucleus where its positive charge and most of its mass are concentrated. They deduced this by measuring how an </span>alpha particle<span> beam is scattered when it strikes a thin metal foil. The experiments were performed between 1908 and 1913 by </span>Hans Geiger<span> and </span>Ernest Marsden<span> under the direction of </span>Ernest Rutherford<span> at the Physical Laboratories of the </span>University of Manchester<span>.</span>
