What is the value for the kinetic energy for a n -3 bohr orbit electron in zeptojoules? 1 zeptojoule # 1e-21 joule remember to use canvas-friendly scientific notation (e. g. 1 billionth1e-9) required precision-3% sanity check: answers should be between 50 and 2200.

that tool would be a compass

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

i think tornado but not 100%
