The ground state electron configuration of ground state gaseous neutral platinum is [Xe]. 4f 14 . 5d 9 .
How do you write the electron configuration for platinum?
The ground state electron configuration of ground state gaseous neutral platinum is [Xe]. 4f 14 . 5d 9 .
Why is platinum an electron configuration?
Those elements with such configuration are generally very reactive(SODIUM has one unpaired electron, which is donated by it to reach the nearest noble gas configuration). ... Platinum is called a NOBLE METAL and it is so stable.
What is the electron of platinum?
| Name Platinum | Number of Protons 78 | Number of Neutrons 117 | Number of Electrons 78 | Melting Point 1772.0° C |
|---|
Why does platinum have a weird electron configuration?
Because it is in Group 10, Period 6 and all elements in that group are required to end with the 5d and 6s orbitals. And since it MUST use 6s, it is natural to put 1 electron in it (simply to show it exists, based on the element’s placement on the periodic table).
Where can platinum be found?
The majority (about 80 percent) of platinum is mined in South Africa . Approximately 10 percent is mined in Russia, and the rest is found in North and South America, according to the U.S. Geological Survey.
Why platinum has different configuration?
(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 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.
What is the period of platinum?
| Group 10 1768.2°C, 3214.8°F, 2041.4 K | Period 6 3825°C, 6917°F, 4098 K | Block d 21.5 | Atomic number 78 195.084 | State at 20°C Solid 195 Pt |

Is Platinum an exception in electron configuration?
Electronic Configuration of Platinum
If we follow the Afbau principle the electronic configuration of Pt will be 1s 2 2s 2 p 6 3s 2 p 6 d 10 4s 2 p 6 d 10 f 14 5s 2 p 6 d 8 6s 2 but Pt have an exception . ... Most common oxidation states of the Platinum are +2 and +4.
What is the charge of platinum?
| atomic number 78 | boiling point 3,827 °C (6,920 °F) | specific gravity 21.45 (20 °C) | oxidation states +2, +4 | electron configuration [Xe]4f 14 5d 9 6s 1 |

How can I test platinum at home?
The simplest tests are heating and discoloration . If the item is heated, for example, in a Bunsen flame, platinum will be more difficult or impossible to melt and the platinum will not discolour. The effect of acid is another basic test. None of the common acids will attack Pt.
