Bulge Bracket Hardos discussion

Notes

neild hendrik bohr from Denmark

went to cambridge for his PhD with his translated thesis in English

his father es also an academic and had all sorts odd smart people hanging out at the home which is where bohr and his brother learned so much

Rutherford moved to Montreal and became professor

He worked with Frederick Soddy and found out that radio activity was the transformation of one element into another through the emission of radiation

Alpha particle Frederick thought was a helium atom that had lost two electron's

isotopes were founded by Sodds, the helper of Rutherford in Canada. they were radio elements that shared the same characteristics of other atoms but only differed in weight

it's not the weight of an element that gives it its place in the table of elements. it's actually its nuclear charge.

in the interaction between radiation and between radiation and matter energy was absorbed and omitted in packets of varying size rather than continuously

bohr tried to build a new atom model saying that electrons followed a specified orbits while not releasing any energy

momentum is equal to mass time's velocity

in a straight line

in s circle it's the same but also multiplied by the radius of the circle, in this case the atom

spectroscopy:the study of absorption and emission of radiation by atoms and molecules
