When it comes to the world of metals, there are some that are considered valuable, while others are seen as worthless. Protactinium, formerly known as protoactinium, is a silvery-gray actinide metal with the symbol Pa and atomic number 91. While it is highly reactive and breaks down easily, it is not the most worthless metal out there. In fact, in comparison to other metals, Protactinium is relatively valuable.
Iron is the least expensive metal on the planet and it’s mass is the most plentiful of all the elements. Iron is found in ores which is why it’s so abundant. It also makes up most of Earth’s core, which produces the planet’s magnetic field – protecting us from cosmic rays and solar winds. While it’s not the most valuable, it’s certainly not the most worthless.
When it comes to the most useless metal, Thulium takes the cake. It may seem like the butt of jokes, but it actually has some applications. Thulium is one of the standard 92 elements found in nature and while it may be the most worthless, it still has some uses.
When it comes to the most valuable metal, Rhodium takes the cake. It is 30 times rarer than gold and is highly sought after. It is used in many different industries, including automotive, jewelry and even electronics.
For those looking for metals that will last forever, there are none. While some metals may last for a very long time, they eventually break down and degrade. The so-called “poor metals” are usually considered to include aluminium, gallium, indium, thallium, tin, lead, bismuth, and polonium. Germanium and antimony may also be included in this grouping, although they are usually considered to be metalloids.
Overall, when it comes to the world of metals, there are many different levels of value. Protactinium may not be the most worthless metal out there, but it is still a valuable element. Iron may not be the most valuable, but its mass makes it plentiful and useful. Thulium may be the most worthless, but it still has some applications. And Rhodium is the most valuable metal on the planet, due to its rarity. Whatever your metal needs may be, you can be sure to find something of value.

Is there a useless element?
The periodic table is an incredible tool that scientists have used for centuries to categorize and identify the elements that make up our world. From the most common elements like oxygen and hydrogen to the rarest and most exotic, like uranium and plutonium, the periodic table has something for everyone. But what about the elements that don’t appear on the table, the ones that are so rare they are almost never seen and so useless they don’t even have a name? Is there such a thing as a “useless element”?
The answer is yes, and it’s not just rare elements that are considered useless. Some of the most common elements can also be classified as useless, depending on how they are used. For example, helium is a noble gas that is often used to fill balloons, but it is also a very expensive resource that is used in a variety of industrial applications. In these cases, helium is considered useless because it is too expensive to use in large quantities or for long periods of time.
What is a useless element?
As mentioned above, some of the most common elements can be considered useless depending on their application. However, there are some elements that are almost never seen and are considered completely useless. For example, protactinium is a highly toxic and extremely rare element that is extracted from spent nuclear fuel for the sole purpose of scientific research. Despite its rarity, protactinium is considered completely useless because it has no practical applications.
Other atoms like oxygen and nitrogen cannot exist independently as they do not have stable electron configurations. These elements are also considered useless because they cannot exist in a form that can be used for any practical purpose.
What are finite resources?
Finite resources are resources that are limited and can eventually run out. Some of these resources, such as sun and wind, are renewable and will likely never run out. However, others, such as minerals, fossil fuels, and even the air we breathe, are non-renewable, so it’s actually possible to lose them forever.
What is the most useful rare-earth element?

Is PR a metal?
Praseodymium, often shortened to PR, is a rare metal found on the periodic table of elements. It is a soft, malleable, silvery-yellow metal and is part of the lanthanide group. Praseodymium is the third most abundant rare earth element and has a wide range of potential applications.
Reaction to Oxygen and Water
Praseodymium reacts slowly with oxygen when exposed to air. This creates a green oxide which does not protect the metal from further oxidation. It is more resistant to corrosion in air than other rare metals, but it must still be stored under oil or coated with plastic. It also reacts rapidly with water.
Storage and Magnetic Properties
The metal is best stored sealed in a plastic covering either in vacuum or in an inert atmosphere. Praseodymium is strongly paramagnetic, and an unstrained single-crystal sample will order antiferromagnetically at 0.03 K (−273.12 °C, or −459.62 °F). However, if praseodymium is strained, it may order at temperatures as high as about 20 K (−253 °C, or −424 °F).
Uses of Praseodymium
A major use of the metal is in a pyrophoric alloy used in cigarette lighter flints. Praseodymium compounds have different uses as well. The oxide is used in carbon electrodes for arc lighting, and it is known for its ability to give glass a nice yellow colour. This glass filters out the infrared radiation, so it is used in the goggles which protect the eyes of welders. The salts are used to colour enamel and glass.
Praseodymium is a rare metal found on the periodic table of elements. It is a soft, malleable, silvery-yellow metal and is part of the lanthanide group.
