Chemical elements that pass through electronic devices were added to the "Endangered List"



Scientists have created a list of items used in everyday gadgets.

Some materials commonly used in mobile phones and other devices are listed as "a serious threat". This includes gallium, arsenic, yttrium and silver.

Scientists have developed a periodic table that highlights the scarcity of 90 natural elements, with around 30 used in mobile phones.

It highlights the lack of 90 natural elements with about 30 used in mobile phones

The updated periodic table (pictured ) was the goal is to noted the paucity of the 90 natural elements, with about 30 used in mobile phones [19659008] It is estimated that around 10 million smartphones are discarded or replaced each month in the European Union alone. Scientists have expressed concerns that there will be an increasing shortage of some elements due to limited supply, the elements that are in conflict zones and the inability to fully recycle.

The European Chemical Society (EuChemS) represents more than 160,000 chemists and developed the table to highlight both the remaining availability of all 90 elements and their vulnerability.

The table will be presented today in the European Parliament by Catherine Stichler and Claire Moody.

The event will also highlight the discovery of the oldest known recent table of the periodic table opened last year at the University of St Andrews.

Action was taken to certify and preserve the big and fragile graphics after it was found among the old equipment in 2014.

Dmitry Mendeleev made his famous discovery about periodicity in 1869, and the graphics of the University of St. Andrews Professor David Cole-Hamilton, an honorary professor of chemistry at the university, has questioned the replacement of mobile phones every two years and has called on consumers to recycle old phones properly.

Professor Cole-Hamilton said, "It's amazing that everything in the world is made of just 90 building blocks, 90 natural chemical elements.

"There is a limited amount for everyone and we use some so fast that they will be scattered around the world in less than 100 years.

"Many of these items are in jeopardy, so do you really need to change your phone every two years?"

Ms Stihler sai d: "When we mark the 150th anniversary of the periodic table, it is amazing to see it updated for the 21st century.

"It's also deeply worrying to see how many items are on the list of endangered people, including those that make up mobile devices.

"This is a lesson for all of us to take care of the world around us, as these naturally occurring elements will not last forever if we do not increase global recycling levels and governments put in place a real circular economy."

Elements in red on the periodic table are at most at risk of complete exhaustion in the foreseeable future.

A chemical component in the modern world, but not used in mobile phones, which is helium, the second lightest of all elements.

  Ask most of the chemists who have found the periodic table and you will almost certainly get the answer Dmitry Mendeleev (pictured). The Russian scientist is the first to publish a version of the table that we will recognize today in 1969.

Ask most of the chemists who have discovered the periodic table, and you will almost certainly get a response by Dmitri Mendeleyev (pictured). The Russian scientist is the first to publish a version of the table that we will recognize today in 1869.

HOW IS THE PERIODIC TABLE CREATED?

Chemists have always looked for ways to arrange the elements to reflect the similarities between their properties.

The modern periodic table lists the elements in order of increasing the atomic number – the number of protons in the nucleus of the atom

Historically, however, relative atomic masses are used by scientists trying to organize the elements. This is mainly because the idea that atoms are composed of smaller sub-atomic particles – protons, neutrons and electrons – has not been developed. However, the basis of the modern periodic table is well established and even used to predict the properties of undiscovered elements long before the concept of the atomic number is developed.

Ask most chemists who have found the periodic table, and you will almost certainly get the answer, Dmitry Mendeleev.

The Russian scientist is the first to publish a version of the chart we will recognize today in 1869, but does he deserve all the credit?

A number of other chemists before Mendeleev explore the patterns of the properties of the elements that were known at that time.

The earliest attempt to classify the elements was in 1789 when Antoine Lavalier grouped the elements based on their properties in gases, non-metals, metals and land.

Several other attempts were grouped in the next decades.

In 1829, Johann Debereren recognizes the triads of elements with chemically similar properties, such as lithium, sodium and potassium, and shows that the properties of the middle element can be predicted by the properties of the other two

while at a conference in Karlsruhe , Germany did not get a more accurate list of the atomic mass of the elements in 1860, real progress was made towards the discovery of the modern periodic table.

Professor David Cole-Hamilton called on people not to release birthday balloons in the atmosphere, as inert gas is needed for MRI scanning and deep-sea diving.

There is no chemical way of producing helium; Earth supplies come from very slow radioactive degradation of alpha, which occurs in the rocks.

He said, "Having balloons with helium on your birthday, you can prevent people from having an MRI scan."

"We recycle it from MRI scanning and most of it from deepwater diving, but we are not

" In both applications it is recycled, but helium is very light, if it falls into the atmosphere it can escape. ] "If we recycle, I think it will be good, but if you gradually put bubbles into the atmosphere, then the time will be shorter."

"The term is shorter than Indian ten years."

The professor explained of the world that about six years helium is supplied by a mine in

Smartphones could become inaccessible without better recycling not the chemicals in them, he added.

  The periodic table (pictured) found during laboratory testing is considered to be the oldest in the world, the school table dating back to about 1885 was found in the chemical Faculty of St. Andrews University

] Professor Cole-Hamilton added supplies to Indian, co it is used to create smartphone and television screens that had to do after 20 years.

Indium is also used in optical fiber lasers for cold welding of electrical components and in blue LEDs

He said: "This ore will run out in about 20 years at the speed we use. We will be able to [build mobile phones] but it will become much more expensive

"We will have to pay more for it, and probably people at the bottom of the spectrum of economic activity will find everybody much more difficult, but can it

"But I think this will not happen because scientists are waking up to the fact that this is a problem."

Describing what he thinks should happen to avoid exhaustion of the elements, "Above all, we need to reduce the number of mobile phones. We are exchanging one million mobile phones in the UK every month.

Second, we need to be able to replace the battery, then we need to recycle all the elements in it and we need to look for replacements that are more abundant

Asked who is responsible, he said, "The consumer and, of course, the manufacturers because they want to sell more phones want to change their mobile phone more often.

a recycling process for materials. & # 39;

Mobile phones and other electronic devices rely on many electronics that may soon be in short supply. Many are still in surplus, but some of them will potentially disappear naturally in the next century.
