Silver has a threshold frequency of 1040 THz, while gold has a threshold frequency of 1330 THz. Lasers having a wavelength of 315 nm are shone on sheets of silver and gold in a photoelectric effect experiment. Will any electrons be ejected from the samples? Electrons will not be ejected from the silver or the gold sheets. Electrons will be ejected from the gold sheet but not from the silver sheet. Electrons will be ejected from the silver sheet but not from the gold sheet. Electrons will be ejected from both the silver and the gold sheets, and the electrons ejected from gold sheet will have more kinetic energy than the electrons ejected from the silver sheet. Electrons will be ejected from both the silver and the gold sheets, and the electrons ejected from silver sheet will have more kinetic energy than the electrons ejected from the gold sheet.

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.
