Palladium is a chemical element with symbol Pd and atomic number 46. It is a rare and lustrous silvery-white metal discovered in 1803 by William Hyde Wollaston. He named it after the asteroid Pallas, which was itself named after the epithet of the Greek goddess Athena, acquired by her when she slew Pallas. Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). These have similar chemical properties, but palladium has the lowest melting point and is the least dense of them.
Over half of the supply of palladium and its congener platinum goes into catalytic converters, which convert up to 90% of harmful gases from auto exhaust (hydrocarbons, carbon monoxide, and nitrogen dioxide) into less-harmful substances (nitrogen, carbon dioxide and water vapor). Palladium is also used in electronics, dentistry, medicine, hydrogen purification, chemical applications, groundwater treatment and jewelry. Palladium plays a key role in the technology used for fuel cells, which combine hydrogen and oxygen to produce electricity, heat, and water.
The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number (number of protons), electron configurations, and recurring chemical properties. This ordering shows periodic trends, such as elements with similar behavior in the same column. It also shows four rectangular blocks with some approximately similar chemical properties. In general, within one row (period) the elements are metals on the lefthand side, and non-metals on the righthand side.
The rows of the table are called periods; the columns are called groups. Six groups (columns) have names as well as numbers: for example, group 17 elements are the halogens; and group 18, the noble gases. The periodic table can be used to derive relationships between the properties of the elements, and predict the properties of new elements yet to be discovered or synthesized. The periodic table provides a useful framework for analyzing chemical behavior, and is widely used in chemistry and other sciences.
Welcome to the Investors Trading Academy talking glossary of financial terms and events. Our word of the day is “Palladium”. Palladium is an important component in electronics, and is used in many new technologies such as fuel cells. As a commodity, it has drawn the attention of investors because it is not easily substituted, and is an important component of catalytic converters. Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals. It is a metal used in many types of manufacturing processes and is found in electronics and industrial products. Palladium is an element found in the periodic table (atomic number 46), and is considered to be rare. The majority of the world's supply comes from mines located in the Unit...
This video illustrates the visual differences between the white metals used in the jewellery industry. It shows the difference between Palladium, Platinum, White Gold & Titanium. It also explains why most jewellery shops sell white gold that changes colour & why RING jewellers white gold does not!

Monolithic Ceramic Capacitors (MLCC's) from older electronics contain up to 2% Palladium & 10% Silver by weight depending on processing methods and quality of mlcc. Whilst very current mlcc's may contain less Palladium then before, those high end electronics are just coming into play, most electronics a scrapper will find is 4 years old or more, meaning e-waste of today can still be loaded with high Pd content mlcc's. MLCC's from factory supplies that are sold in 1kg bags online do not contain much Palladium or Silver, Only buy MLCC's from scrapped PC's which are higher grade then aftermarket copies. we are all trying to learn so if you have more info to share about mlcc's and palladium recovery then tell us about it. Palladium spot price is holding steady so well worth picking mlcc's....
For our updated Palladium video, we are mining the Royal Society archives for the story of its discovery - a tale of money, an asteroid and stolen samples? The discovery was made by William Hyde Wollaston.

There's a Wonderland for Alice,
There's a tall beanstalk for Jack,
The sleepy train will take you there,
So safely down the track,
With the sandman at the throttle,
You'll be off to dreams and back,
It's pillow time again.
You will meet all your storybook friends
As you go down Mother Goose Lane,
Romp with Jack and Jill,
Up and down the hill,
And try to put Humpty together again.
Close your sleepy eyes and listen
While we take a little hop,
The candy whistle's blowing,
Don't you miss your station stop,
So, good night, my weary farer,
Pleasant dreams to you, old top,
It's pillow time again.
You will meet all your storybook friends
As you go down Mother Goose Lane,
Romp with Jack and Jill,
Up and down the hill,
And try to put Humpty together again.
Close your sleepy eyes and listen
While we take a little hop,
The candy whistle's blowing,
Don't you miss your station stop,
So, good night, my weary farer,
Pleasant dreams to you, old top,
It's pillow time again,
It's pillow time again,
It's pillow time again,
It's pillow time again,
It's pillow-pillow time again.
