Iwill give ! because of the structure of the electron cloud, as particles were radiated onto a gold atom, what was observed during rutherford's experiment? (5 points) select one: a. electron cloud absorbed the particles b. particles that struck the nucleus went straight c. particles that struck the nucleus are absorbed d. electron cloud allowed the particles to pass through

Order the following from smallest to largest atom, electron, quark, proton, neutron, molecule, nucleus

16. why must the number of electrons lost equal the number of electrons gained in every redox reaction? use 3 – 4 sentences in your own words to address this question. 18. what type of radiation is emitted when chromium-51 decays into manganese-51? show the nuclear equation that leads you to this answer. 19. a radioactive nucleus alpha decays to yield a sodium-24 nucleus in 14.8 hours. what was the identity of the original nucleus? show the nuclear equation that leads you to this answer.

Select all of the statements which are true. electrons are located in shells or orbits around the atom. electrons orbit slowly around the atom. electrons travel in one flat path around the nucleus of an atom. the valence of an atom is determined by the number of electrons in the atom's outermost shell.
