Explanation:
chlo·ro·phyll
noun
a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. Its molecule contains a magnesium atom held in a porphyrin ring.
The transition metals can form a variety of complexes because can lose as well as accept electrons .
<h3>What are transition elements?</h3>
The transition elements are those elements that are foud at the middle part of the periodic table having incompletely filled d orbitals.
These elements have a variable oxidation state. They can loose and accept electrons easily and this is why transition metal elements can form a variety of complexes with different colors and other properties.
