Many energy levels of electrons and low effective nuclear charge/low Coulombic force.
p px py pz
the principal energy levels of valence electrons increase.
because it lower than Ba as you go down ionization energy increases
The principal quantum number describes the size of the orbital. Because they have opposite electrical charges, electrons MORE.
The nuclear charge increases and electrons are added to successively higher principal energy levels.
Principal energy levels are an atom's major energy levels, ranging in value from 1 to 7. Energy sublevels are contained within principal energy levels, and their number increases as the value of the principal energy level increases.

Principal quantum numbers (n).

Each period corresponds to the number of shells (energy levels) contained in the atom.
Each period in the periodic table corresponds to a principal energy level.http://wiki.answers.com/Each_period_in_the_periodic_table_corresponds_to_what#ixzz18t3CP9fk
There are nuclear energy levels, but they're not "the same" as the electronic energy levels.
The answer is B
Transition elements can form bonds by losing electrons from both the outermost and next to the outermost principal energy levels.

the principal energy levels of valence electrons increase.
