1. Be careful; nitrogen is NOT a transition element. The element you are thinking of is nickel,
which is a transition element and has the chemical symbol "Ni" (different from that of nitrogen,
which is "N"). Now, transition elements are those elements whose atoms have incomplete d-
sub-shells, meaning that their electron configurations include a partly, not completely, filled d-
sub-shell.
(1) Let's take a look at the electron configuration of nickel:
[Ar] 4s2 3d8
Notice that the d subshell, only contains 8 electrons, while elements whose d sub-shells are full
have 10 electrons. Also, sorry, but nitrogen can't possibly be a transition element because it
doesn't have any d electrons in its electron configuration,
(2) Why are such special elements called "transition elements"?
Transition elements are placed on the periodic table in the intermediate d-block, which is the
relatively large middle section of the table which partitions alkali metals and alkaline earth
metals to the left of the table, and metalloids and non-metal elements to the right of the table.
Also, the physiochemical properties of transition elements are similarly "in transition"; the
unpaired, low-reactivity d electrons cause these elements to have several different oxidation
states, thus causing them to be in a state of transition.
