As electrons get to higher and higher energy levels, the harder it
is to locate them because the radius of the ________________
is greater. Thus, the probability of locating an electron will be
more difficult. 16 05-Sep-13 Radial Probability Graphically

3d Distance from nucleus Summary
• Zeff is always less than the charge on the nucleus because
inner electrons shield or screen the outer electron.
• In a many-electron atom, for a given value of n, Zeff
decreases with increasing value of l.
• The larger the value of Zeff for an electron, the more stable
it is. as it is feeling the pull by the protons.
• In a many-electron atom, for a given value of n, the
energy of an orbital increases with increasing value of l. 19...
