What is the orbital diagram?
Orbital diagrams are a pictorial description of electrons in an atom. In order to figure out where electrons go in an atom we have to follow 3 main rules. The first one being the Auf Bau Principle, the Auf Bau Principle states that each electron occupies the lowest energy orbital available.
How many orbitals does platinum have?
Platinum Atomic and Orbital Properties
Platinum atoms have 78 electrons and the electronic shell structure is [2, 8, 18, 32, 17, 1] with Atomic Term Symbol (Quantum Numbers) 3D3.
What is platinum electron configuration?
Why Platinum is 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. … HOW IS THIS STABILITY ACHIEVED WITH SUCH A CONFIGURATION.
How many shells does platinum have?
|Platinum is a transition metal
|Neutrons in most abundant isotope:
|2, 8, 18, 32, 17, 1
|[Xe] 4f14 5d9 6s1
What is the symbol of platinum?
Is platinum an element?
platinum (Pt), chemical element, the best known and most widely used of the six platinum metals of Groups 8–10, Periods 5 and 6, of the periodic table. A very heavy, precious, silver-white metal, platinum is soft and ductile and has a high melting point and good resistance to corrosion and chemical attack.
Why platinum has abnormal electronic 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).
How many protons and electrons are in platinum?
Platinum atoms have 78 electrons and 78 protons with 117 neutrons in the most abundant isotope.
How platinum is formed?
The metal is formed when minerals are eroded from their original spot and then carried by water somewhere else (this is called stream bed mining or alluvial mining). Workers sift through the sand or mud looking for gold, diamonds or platinum. Nowadays, platinum is more likely to be mined as ore from deep underground.
How is platinum found in nature?
Platinum in the Earth’s crust originates from ultra-mafic igneous rocks. It can therefore be associated with rocks like chromite and olivine. In nature, pure platinum is unknown and well formed crystals are very rare. Platinum is typically found as nuggets and grains.
How do you find platinum?
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.
Is platinum a ore?
Platinum is also mined as an ore . Platinum ores such as sperrylite and cooperite may be mined when they are found in quantities that make extraction economically feasible. In other situations, platinum is obtained as a by-product when ores of other metals, such as copper and nickel, are refined.
Is platinum a mineral or element?
Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name is derived from Spanish platina, a diminutive of plata “silver”.
Is platinum a silver?
While at first glance both silver and platinum appear silver in color, the two metals are actually easily discernible to the naked eye. Both have gray undertones, unlike white gold which has a warmer, yellow undertone, but platinum is much brighter and shinier and silver has a duller, gray appearance.
How do you extract platinum from catalytic converters?
To remove the platinum coating on the catalyst pieces, the catalyst pieces must be removed from the converter. This is done simply by turning up the catalytic converter lengthwise and pounding on one end with a blunt instrument until the catalyst pieces start to fall out of the lower, open end of the converter.
Is platinum a Hardmode ore?
Pre-Hardmode ores: Copper, Tin, Iron, Lead, Silver, Tungsten, Gold, and Platinum Ores, Hellstone, Obsidian, and Meteorite. Hardmode ores: Cobalt, Palladium, Mythril, Orichalcum, Adamantite, Titanium, and Chlorophyte Ores.
Is platinum a gold?
Because platinum rings are heavier and more pure than gold, they are more valuable. While gold and platinum are similar in price per gram, platinum is denser, so more of it is used when making a ring. Additionally, platinum rings are usually 95% pure platinum, while 14k gold is only 58.5% gold (18k gold is 75% gold).
Is platinum a white gold?
While Platinum is a naturally white metal, White Gold is made by combining pure gold (which is yellow in colour) with alloying metals such as Palladium. Because of the yellow metal content, White Gold is actually slightly grey/off-white in colour. This can be corrected by a surface treatment called Rhodium plating.
Can platinum be marked 925?
When an item is stamped “925 Platinum,” it means that it is made of 92.5% platinum. … You will also find pieces of jewelry that are marked “925 Silver” and “925 Gold.” Those terms mean exactly what the “925 Platinum” term means – that the item you are looking at contains 92.5% silver or gold.
Can you pawn platinum?
Can platinum be pawned? Yes, you can pawn platinum just like you can pawn any other precious metal like gold or silver. That said, if you would like to pawn your platinum it’s important to find a reputable pawn shop that will give you a fair price for your metal.
