You have an unknown metal and a purple (violet) laser. When you shine the purple laser on the metal, nothing happens. You grab a different color laser with the same intensity, hoping to eject electrons from the metal. Which of these lasers MIGHT eject an electron? Both blue and green None of these lasers have the potential to eject electrons. All of these lasers will eject electrons. Both red and yellow Yellow Green Blue Red

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.
