The table below shows two conclusions about atoms based on experiments by Rutherford and Bohr. Name of scientist Experimental Process Conclusion about atoms Rutherford Fire radioactive particles through thin gold foils and detect them on a screen The nucleus is the center of the atom with electrons revolving around it in orbits Bohr Check the spinning motion of electrons Electrons are found outside the nucleus of the atom at various levels called shells, arranged like layers of an onion Which of these statements best explains why Rutherford and Bohr visualized the atom differently? They studied atoms of different elements. They had different focuses in their experimental process. They did not believe in agreeing on a single model of the atom. They did not have instruments to take accurate measurements.
