British Dictionary definitions for gadolinium Symbol: Gd; atomic no: 64; atomic wt: 157.25; valency: 3; relative density: 7.901; melting pt: 1313±°C; boiling pt: 3273°C (approx.)
What is gadolinium used for in everyday life?
The major uses of gadolinium compounds include hosts for phosphors for fluorescent lamps, X-ray intensifying screens, and scintillators for X-ray tomography, and as a magnetic resonance imaging (MRI) contrast agent (in the form of water-soluble chelates).
What type of metal is gadolinium?
Gadolinium is a soft, shiny, ductile, silvery metal belonging to the lanthanide group of the periodic chart. The metal does not tarnish in dry air but an oxide film forms in moist air.
What Colour is gadolinium?
Gadolinium: Gadolinium (Gd) is a silvery white rare earth metal. That’s why silvery background is used in the picture to represent gadolinium. Gadolinium forms compounds which are used for making phosphors for color television tubes.

How do you write the electron configuration for gadolinium?
Thus, the electronic configuration of Gd(Z=64) is [Xe]4f75d16s2.
Why is gadolinium toxic?
Gadolinium is a rare earth metal that aligns with an MRI’s powerful magnetic field, but it is also toxic, so in its injectable form the metal is bound to chelating molecules to block its dangerous effects. Most of these molecules are then filtered through the kidneys and eliminated.
What are three interesting facts about gadolinium?
Here are some interesting facts about this metal:
- Gadolinium is silvery, malleable, ductile metal with a metallic sheen.
- Gadolinium, like other rare earth elements, is not found in pure form in nature.
- At low temperatures, gadolinium is more ferromagnetic than iron.
- Gadolinium has superconductive properties.

Is gadolinium a toxic metal?
Gadolinium is a rare earth metal that aligns with an MRI’s powerful magnetic field, but it is also toxic, so in its injectable form the metal is bound to chelating molecules to block its dangerous effects.
What is the symbol for dysprosium?
DyDysprosium / Symbol
Dysprosium is the chemical element with the symbol Dy and atomic number 66. It is a rare-earth element in the lanthanide series with a metallic silver luster.
What is the use of dysprosium?
Dysprosium is used in control rods for nuclear reactors because of its relatively high neutron-absorption cross section; its compounds have been used for making laser materials and phosphor activators, and in metal halide lamps.
What is the electronic configuration of gadolinium atomic number64?
Gadolinium (Gd) has a 4f75d16s2 electronic configuration outside the [Xe] core.
What is the atomic number of gadolinium?
64Gadolinium / Atomic number
Is gadolinium safe for humans?
Gadolinium is extremely safe, with serious adverse reactions occurring in roughly 0.03 percent of all doses. As researchers noted in studies from 2008 and 2015 of patients exposed to gadolinium over time, those who were neither pregnant nor in kidney failure have rarely experienced side effects.
Is gadolinium harmful to humans?
By itself, gadolinium is toxic. When used in contrast agents, the rare earth metal is bonded with a chelating agent. Bound to chelates, which vary across different gadolinium-based contrast agents (GBCAs), gadolinium is eliminated from the body.
What is the 64th element?
Gadolinium – Element information, properties and uses | Periodic Table.
Is gadolinium toxic to humans?
Toxicity is a side effect of GBCAs that can occur within hours after undergoing an MRI scan with one of these contrast agents. Or it can manifest years later in people who have gadolinium buildup in their bodies. Symptoms vary from person to person. The severity ranges from mild to severe.
What does dysprosium look like?
Characteristics: Dysprosium is a bright, soft, silvery-white, rare earth metal. It tarnishes slowly in air at room temperature and dissolves in both dilute and concentrated acids.
