Rutherford created a planetary model for atoms after his experiments. imagine if rutherford's idea that electrons radiate energy while orbiting around a nucleus was true. which other model or scientific idea would have been strengthened by this? bohr's model of the atom would have been strengthened because bohr proposed that the energy of electrons is continuous. bohr's model of the atom would have been strengthened because bohr proposed that electrons can have only certain energy values. the idea that atoms are unstable would have been strengthened because the orbiting electron would lose energy and fall into the nucleus. the idea that atoms are unstable would be strengthened because the orbiting electron would absorb energy while moving and escape the pull from the nucleus.

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.

Pegmatites are igneous rocks in which the individual minerals are very large. typically, the minerals are all light-colored quartz, feldspar and muscovite. if you were given a black and white photograph of a pegmatite in a quarry (where the rock has been blasted and broken), what physical properties could you use to identify those three minerals in this hypothetical photo? describe each mineral and the specific diagnostic properties. be specific.
