ATOMIC MODEL
• See Atomic Model Timeline worksheet for specifics.
ELECTRONS
• Quantum Mechanical (QM) Model- This is the currently accepted model of the atom.
o Erwin Schrödinger wrote an equation which describes _______________________________
__________________________________________________________________________.
▪ These locations are not definite because of the Heisenberg Uncertainty Principle.
• Each of the following terms gives a more specific description of where an electron probably is.
In Chemistry… In CB South, for example…
o Energy level, n
o Sublevel, l
o Orbital, ml
o Spin, s
• Energy Levels, n-
o An electron may NOT be found _____
_______________________________.
o Higher n = higher energy (typically)
o To determine how many electrons fit into a given
energy level, use this formula: _____
o The maximum number of electrons is 32.
o Electrons will occupy the
________________________________ first.
• Sublevels (subshells), l-
o Energy levels contain __________________ consisting of ________________ (shapes)
where there is a ________________ probability of finding an __________________.
o Orbitals can hold up to _____________ electrons.
o Sublevels hold the orbitals and can hold 1, 3, 5, or 7 orbitals.
