A transition metal ion exists in its highest oxidation state. It is expected to behave as :
a chelating agent
a central metal in a coordination compound
an oxidising agent
a reducing agent
C.
an oxidising agent
A transition metal ion exists in the highest oxidation states. It is expected to behave as an oxidising agent.
The highest magneticmoment is shown by the transition metal ion with the configuration :
3d2
3d5
3d7
3d9
In the periodic table metals usually used as catalysts belong to
f-block
d-block
p-block
s-block
An element with atomic number 21 is a
halogen
representative element
transition element
alkali metal
Mercury is a liquid metal because
it has a completely filled s orbital
it has a small atomic size
it has a completely filled d orbital that prevents d-d overlapping of orbitals
it has a completely filled d orbital that causes d-d overlapping
