The work function (binding energy) is the energy that must be supplied to cause the release of an electron from a photoelectric material. The corresponding photon frequency is the threshold frequency. The higher the energy of the incident light, the more kinetic energy the electrons have in moving away from the surface. The work function for nickel (used in rechargeable batteries) is equivalent to 483.4 kJ/mol photons. Use this information to calculate the energy, wavelength, and velocity of ejected electrons. What is the maximum wavelength (in nm) at which the electron can be removed from nickel? h = 6.626 x 10-34 J·s; C = 2.998 x 108 m/s

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.
