Answer:
.
Step-by-step explanation:
Since the atomic number of vanadium is
, there would be
electrons in this atom.
The maximum number of electrons in each subshell (
,
,
, etc.) is:
for each
subshell (
,
,
, etc.),
for each
subshell (
,
, etc.,) and
for each
subshell (e.g.,
.)
By the Aufbau Principle, the first few electron subshells are filled in the following order:
,
,
,
,
,
,
.
To find the electron configuration of Vanadium, start by filling the subshells in the order from the Aufbau Principle. Keep track of the total number of electrons that be placed so far:
(the
subshell is now full,
electrons placed in total.)
(
electrons in total.)
(
electrons in total.)
(
electrons in total.)
(
electrons in total.)
(
electrons in total.)
By the Aufbau Principle, the next subshell would be
, which holds up to
electrons. However, since there are only
more electrons to be placed, the
subshell of this atom will not be entirely filled:
.
The resultant electron configuration of this atom would be:
.
