** Atom and Introduction to Nuclear physics ** Introduction Alpha-particle scattering 2.1 Experimental set-up ➢ Alpha particle o is a high-energy helium nucleus with 2 protons and 2 neutrons. o has 2 positive charges. ➢ Gold foil was chosen since it has a high atomic mass. Thin gold foil‚ ~10-6m was bombarded by high-energy alpha particles. ➢ Angular deflections/ scattering of alpha particles were measured by observing

nuclear fusion play in the Sun? Nuclear fusion is when two atomic nuclei combine into one heavier nucleus. Nuclear fusion plays the role of providing energy for the Sun. This energy is created as nuclear fusion occurs following the steps of the proton-proton chain reaction. 3. How are sunspots and solar flares similar? How are they different? Sunspots and solar flares are similar in the way that magnetic fields are involved‚ or are believed to be involved with both occurrences. Sunspots occur where

bases required the transfer of a proton in order for there to be a reaction. An acid will donate a proton (proton donor)‚ forming what is considered to be a conjugate base. When the base accepts a proton (proton acceptor)‚ the conjugate acid is formed. In the example below‚ we have Ammonia and Water forming Ammonium and a Hydroxide ion. In the forward reaction‚ H2O loses a proton‚ forming OH-. This becomes

accurate and continue moving through the body until they exit‚ some of them are absorbed into surrounding healthy tissue. The most common areas of the body that are damaged by this type of radiation therapy is the bladder and other surrounding organs (Proton Therapy). Radiation itself is a known cause of cancer and this risk may outweigh the benefits for some when selecting a treatment option. Aside from potentially damaging normal functioning tissue‚ X-ray therapy causes minimal side effects in its

The mitochondrion obtains its source of energy from the movement of protons down a concentration gradient (chemiosmosis)‚ this difference in gradient is what directly powers formation of ATP. Proton by proton they cross ATP Synthase were ADP will join a phosphate to form ATP. A total of 32 ATP are form from
