Elements (metals) of the first transition series
The first transition series contains the elements that have the 3d
subshell as their outermost, highest-energy subshell. In terms of electron
allocation, the 3d subshell fills after the 4s subshell. Many of the
properties of the transition metals can be related to the 4s and 3d
All 10 elements in the first transition series are metals. Only scandium
and titanium are not necessary for good health.
There is about five grams of iron in your body. Most of this is
incorporated into haemoglobin molecules, which transport oxygen around the
body, and myoglobin, which is used to store oxygen in tissues. A deficiency
of copper or manganese can cause bone deficiencies. Cobalt is a component
of vitamin B, which is required for the formation of red blood cells.
