The Bohr model

Students often get confused between Rutherford’s model and Bohr model of an atom. They interpret the postulates of both these models to be the same, which is incorrect. Rutherford’s model differs from Bohr’s model in the following ways:

Question

Can you explain to me how this is solved - If 112 g of silicon (Si) react completely with 64 g of oxygen (O) to form silica (SiO2), what is the atomic weight of silicon? I am supposed to solve it not using a periodic table and am very confused as to how to get to the answer in the book, 28.

When neptunium (Np) and plutonium (Pu) were discov-ered, the periodic table did not include the actinides, so these el-ements were placed in Group 7B(7) and 8B(8). When americium(Am) and curium (Cm) were synthesized, they were placed inGroup 8B(9) and 8B(10). However, during chemical isolationprocedures, Glenn Seaborg and his group, who had synthesizedthese elements, could not find their compounds among othercompounds of these groups, which led Seaborg to suggest theywere part of a new inner transition series. (a) How do the elec-tron configurations of these elements support Seaborg’s sugges-tion? (b) The highest fluorides of Np and Pu are hexafluorides, asis the highest fluoride of uranium. How does this chemical evi-dence support the placement of Np and Pu as inner transition el-ements rather than transition elements?

Before the neutron was discovered, the only possible constitution of a nucleus with a given (A,Z) was A protons and (A-Z) electrons, leaving a net charge of +Ze. Early indications were that the nitrogen nucleus (A = 14,Z = 7) had a total angular mo- mentum that was an integral multiple of ħ. Is this consistent with a nucleus made of A protons and A-Z electrons? How does the inclusion of neutrons change things?
