What is platinum electron configuration?
[Xe] 4f14 5d9 6s1
Why is platinum an electron configuration?
the observed electronic configuration of platinum (Z=78) is [Xe] 4f14 5d9 6s1. It has one unpaired electron in its d-orbital and one unpaired electron in its s-orbital. Platinum is called a NOBLE METAL and it is so stable.
Why is the electron configuration of platinum different?
(i)It can be looked as that the 5d sub shell electrons are shielded better by the completely filled 4f sub shell electrons to make 5d to be lower energy than the 6s orbital. (ii) This energy difference decreases all the more due to another effect called EINSTEIN’S RELATIVISTIC EFFECT.
Why platinum has d9 configuration?
It comes from relativistic effects, electron correlation and shielding effects. Often it is said that the outer orbitals are less compact than the inner ones, which is true if one calculates and analyses them, but a stronger effect is that outer electrons are shielded and therefore the nucleus attraction is weaker.
Why is platinum 5d9 6s1?
Platinum is the element present in d ” block element . Atomic number of Platinum is 78. Electronic configuration of Pt is [Xe] 4f14, 5d9 , 6s1. Pt ^+4 means that 4 electrons are removed from the valence shell of the Pt atom , forming a cation with (+4) positive charge on it .
Is Platinum an exception?
For example, ruthenium, rhodium, silver and platinum are all exceptions to the Aufbau principle because of filled or half-filled subshells. In the lower atomic numbers, the difference in energy levels for the normal sequence of electron shells is larger and exceptions are not as common.
Why is platinum so stable?
Although platinum atom has an electron configuration of [Xe] 4f14 5d9 6s1, its electron configuration in metal platinum is most likely [Xe] 4f14 5d10 6s0, which has a closed subshell. Now with this config its obvious for the metal to be highly stable.
Is platinum bad for your health?
* Platinum may cause a skin allergy. If allergy develops, very low future exposure can cause itching and a skin rash. * Platinum may cause an asthma-like allergy. Future exposure can cause asthma attacks with shortness of breath, wheezing, cough, and/or chest tightness.
Total worldwide reserves of platinum metals are estimated to be some 69,000 metric tons. Almost all of it, some 95 percent, is located in the Earth’s crust of South Africa….Platinum metal reserves worldwide as of 2020, by country (in metric tons)
Platinum is 30 times more rare than gold. If all the platinum ever mined were melted and poured into an Olympic-sized pool, the platinum would barely reach your ankles.
Who is the largest producer of platinum?
Anglo Platinum in South Africa is the world’s largest platinum producer. A subsidiary of Anglo American, the company processes nearly 40 percent of all newly mined platinum annually. The Anglo Platinum precious metal refinery (PMR) is located near two of the largest platinum mines in the world.

Where is platinum found in nature?
Platinum is found in its pure native form or in platiniridium, a natural alloy of platinum and iridium. Platinum is present in thin sulfide layers in certain mafic igneous bodies and is mined in Canada, Russia, South Africa, the USA, Zimbabwe and Australia.
What things contain platinum?
The versatile platinum group metals (PGMs)”platinum, palladium, rhodium, iridium, ruthenium and osmium”can be found in products we use every day, such as catalytic converters, drugs and medical devices, and many, many electronic devices.
How did platinum get its name?
The name is derived from the Spanish ‘platina’, meaning little silver.
