Integrated Physics and Chemistry – Unit 2: The Structure of Matter Experiment: Atomic Structure In this experiment‚ you will have a chance to test the hypothesis that Ernest Rutherford used when determining the size of the nucleus. In his "gold foil experiment‚" Rutherford shot alpha particles at gold atoms. Once he realized that the alpha particles were hitting a concentrated positive mass‚ he developed the nuclear model of the atom. Next‚ he set out to determine the relative size of the nucleus

Richmond Manuel Ulan sa Tag-araw (Reaction Paper) Before I watched the film‚ I am aware that the genre and contents of it is all about the Climate Change and Global Warming. Having that thought‚ I know that it will be related to our subject which is all about environmental health. If our mother earth’s health is at risk‚ everything that is involved to it is also affected. If we are doing wrong to our mother earth‚ it will surely give us a negative feedback. For me‚ our nature as a person is

Dalton was the first scientist to help contribute to the atomic theory. He based his thought process off of Democritus‚ an ancient Greek philosopher‚ who stated that at one point you will not be able to break down matter anymore‚ he called this basic building block an atom (meaning not divisible). Democritus believed that everything around us such as metal‚ water‚ and wood were atoms‚ but Dalton believed and proved that it could be more basic than that. He started thinking of compounds such as water

judgment and misconduct that the past government had put in place. The constitution hill also briefly illustrates what South Africa’s past was like as there was apartheid and non-whites had no rights. It is important for our history and what made SA what it is today and because many of our great leaders and freedom fighters have been in the constitutional hill. It is an important part of history because it shows the democratic state that South Africans were in before 1994 and the pain‚ struggle
