Transition Metals and d-Block Metal Chemistry Flashcards
as elements with an incomplete d subshell or elements that can form a cation with an incomplete d subshell.
transition metals
Lanthanides and actinides have been called inner transition metals in the past. Nowadays, they are referred to as ______
f-block elements.
Each group of d-block metals is formed by three members and is therefore called a -______
triad
platinum group metals?
ruthenium (Ru), osmium (Os), palladium (Pd) and platinum (Pt).
refers to d-block metals of the second and third row
Heavierd-block metals
T or F
Nearly all d-block metals are hard, malleable and ductile, and conduct electricity and heat. Most of them will form one of the typical metal structures; except Mn, Zn, Cd and Hg.
T
only d-block elements known to produce a magnetic field.
iron (Fe), cobalt (Co) and nickel (Ni)
d-Block metals tend to readily form complexes with a characteristic color if their ground-state electronic configuration is different from d0 or d10. Complex formation is often characterized by a color change. For example,
[CoF6]3−is ____?,
[Co(NH3)H2O]3+is ____?
[Co(H2O)6]3+is ____?.
Green
Red
Blue
defined as chemical structures that consist of a central atom or metal ion, and the surrounding molecules or anions are called ligands
Coordination complexes
Group 10 consists of the nonradioactive members _________as well as
the radioactive element ______
nonradioactive members:
nickel (Ni), palladium (Pd) and platinum (Pt)
radioactive element:
darmstadtium (Ds)
is used as a hydrogenation catalyst, for H2/D2/T2 separation and purification as well as a catalyst in the Wackerprocess.
Palladium
was the first organo palladium reaction that was applied on an industrial scale. This facilitates the oxidation of ethylene to acetaldehyde.
Wackerprocess
also intensively used as a catalyst, for example, in HNO3 production, as oxidation catalysts, in petroleum reforming, in hydrogenations and in many more chemical processes, as well as for jewellery.
Platinum
is a yellow powder; widespread use a chemotherapeutic agent.
CDDP, cisplatinum or cisplatin
The platinum complex binds to DNA and causes cross-linking, which triggers the programmed cell death_____
(apoptosis).
specifically used as an effective therapeutic agent against ovarian, testicular, uterus, bladder and head and neck cancers
Cisplatinis
Group 8: nonradioactive members?
iron (Fe), ruthenium (Ru) and osmium (Os), as well as the radioactive element Hassium (Hs).
T or F
All three nonradioactive elements in silvery white, hard transition metals with a high melting point. in Group 8
T
most common element within the entire earth;most of the earth’s core is____
Iron
are two of the rarest elements on earth.
Ruthenium and osmium
Iron :Fe (Latin: _____) and atomic number 26.
ferrum
one of the most used metals because of the relatively low production costs and its high strength.
Iron
found in many everyday items, from foodcontainers to screw drivers or any type of machinery.
Iron
are a necessary trace element used by almost all living organisms with the only exceptions being a few prokaryotic organisms that live in iron-poor conditions.
Iron Ions
