Electrons are ejected by the photoelectric effect when the surface of the metal rubidium is illuminated with 300 nm ultraviolet radiation. The kinetic energy of each electron was measured and found to be 3.3 x 10-19 J. What is the maximum wavelength of light that can remove an electron from a sample of rubidium? L What would be the kinetic energy of the electrons if 240 nm light were used?
Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
a. Electrons are ejected by the
What would be the kinetic energy of the electrons if 240 nm light were used?
b. Sulfur and fluorine form several different compounds. Decomposition of a sample of one such compound produced 4.45 g of fluorine and 1.25 g of sulfur, while decomposition of a different compound produced 4.43 g of fluorine and 1.87 g of sulfur.
Calculate the mass of fluorine per gram of sulfur for each, and show that these results are consistent with the Law of Multiple Proportions.
c. Teal-colored light has a wavelength of 491.4 nm. Express this as frequency and wave number.
