"Quantum Numbers and Electron Configurations Explained"

  • Carl Const is a senior high school student from Paranaque National High School.
  • Miguel Calvo Tanola has provided an answer that has not been seen yet.
  • Boron's electron configuration is 1s2 2s2 2p1.
  • Magnesium's electron configuration is 1s2 2s2 2p6 3s2.
  • Miguel Calvo Tanola and Edward have been commended for their participation in the lesson.
  • The four principal quantum numbers are discussed: principal, azimuthal, magnetic, and spin.
  • The principal quantum number (n) describes the energy and distance of an electron from the nucleus.
  • The azimuthal quantum number (l) defines the shape of the orbital and has values of 0, 1, 2, and 3.
  • The magnetic quantum number (m sub L) describes the orientation of electrons in space and the effect of an orbital in a magnetic field.
  • The spin quantum number indicates the spinning of electrons around their own axis and has values of +1/2 and -1/2.
