Filling orbitals - Study guides, Class notes & Summaries

Honors Chemistry Final Exam Review with Certified Solutions What is the term for the energy required to break a bond in one mole of a gaseous molecule? Bond Dissociation Energy What is the name of the rule that describes the filling of orbitals in an atom, stating that electrons occupy degenerate orbitals singly before pairing? Hund’s Rule What is the term for the temperature at which the vapor pressure of a liquid equals the external pressure? Boiling Point What is the ...

Which orbital is the electron in? - Answer-l (L) value which orientation is the electron in? - Answer-m sub L value n value - Answer-use periodic table (period #) L value - Answer-what orbital its in (s, p, d, f) m sub L value - Answer-what orientation of the orbital is it in?---every electron in the atom has unique values for n, l, ml Electron configurations show... - Answer-which orbitals are in an atom and how the electrons fill the orbitals Electron configurations focus on... - Answe...

CHEMISTRY A LEVEL WITH SATISFIED SOLUTIONS What are the two elements which are exceptions to the electron configuration? - CORRECT-The two exceptions for this is copper and chromium. In both cases, the 4s subshell contains only one electron, even though there are electrons in the 3d subshell. To explain this, its because the 3d subshell is more stable when it is either half full, or completely full. So in the case of chromium, by having only one electron in the 4s subshell, ...

Pauli exclusion principle - ACCURATE ANSWERS no two electrons in an atom may possess identical sets of the four quantum numbers Aufbau principal - ACCURATE ANSWERS states that when the electrons of an atom are all in the ground state, they occupy the orbital's of the lowest energy, thereby minimizing the atoms total electronic energy. Hunds rule - ACCURATE ANSWERS when filling a set of degenerate orbitals, the number of unpaired electrons will be maximized and these electrons will have pa...

Introduction to Quantum Mechanics Graded A+ Back to Bohr: Bohr gave us Quantization Quantization means electrons can only exist in certain discrete energy levels (like a staircase, they can only completely be on the first or second stair but never in between stairs different distances from ground) If you recall rings= orbits e- must be in a _______ and e- are different distances(or E) from ________ orbit; nucleus Bohr was Bad: Bohr model of the atom could predict the ____________ _...
