Thallium

Properties and Uses Of Thallium

Thallium is a chemical element, which possess the symbol known as “Tl” alongside an atomic number of 81, just as it is written in the periodic table. The Thallium chemical is said to look similar to a tin, when it is being isolated, but exposing it to air makes it discoloured. The Thallium chemical was discovered by Claude – Auguste  Lamy and William Crookes back in the year, 1861.

As we said earlier the thallium chemical element contains 81 electrons, which resides inside an atom of this element. The electronic configuration of thallium is known as Xe 4f14 5d10 6s2 6p1, and it can be made artificially when you smelt lead and zinc. A fun fact you might not know is that Thallium can also be made, but as a by-product during the production of sulphuric acid.

Now let’s look at a summary of relevant attributes of Thallium:

Uses Of Thallium Chemical Element

Now, let us go through some of the uses of thallium element. the uses of thallium element includes the following:

  • It is used for the production of optic laser and also equipment which are related to optic laser.
  • Thallium is able to help you detect gamma radiation.
  • It is used in glass manufacturing.
  • It has proven to become rodents and insects killers during the early ages.
  • Thallium salts can be used as a skincare treatment, but it is also considered dangerous because it is naturally very toxic for the human skin and this could lead to some side – effects.
  • Thallium is used in infra – red photocells.

Although we couldn’t list all, but these are some of the uses of the thallium chemical element.

The Physical Properties Of The Thallium Chemical Element

According to researches, the thallium chemical element is considered to be a malleable metal, which shares similarity with Lead (Lead possess Atomic Number 82) when it comes to appearance. Now let’s list out some of it’s properties below:

  • The thallium chemical element is very sufficient and available.
  • It’s salts are stated to be toxic and isn’t good to be applied on the skin.
  • It is super soft
  • It melts very easily.
  • It has a kind of bluish – white, when it comes to appearance.

Some Amazing Fun Facts About The Thallium Chemical Element

  1. Do you know that the chemical element, “Thallium” originates from a Greek word, which is known as “Thallos” ?. The word, Thallos simply means green twig.
  2. Do you know according to researches about 25 isotopes of the thallium chemical element has been found ?
  3. Do you know you can find thallium chemical element as a mineral in several elements known as lorandite, hutchinsonite, and crooksite ?

The Chemical Properties Of The Chemical Properties Of The Thallium Chemical Element

So right now let’s look at some of the most important chemical properties of the thallium element, and they are as follow:

  • The thallium element possess a +3 and +1 oxidation state, Although the +1 is considered to be alot stable and also reveals the similar identity to an alkali metal.
  • It also reacts with the air to produce a drey oxide, which can be very poisonous when it experiences enormous heating. below is how the reaction plays out:

2Tl(s) + O2(g) → Tl2O(s)

  • It Produces what is known as thallium hydroxide, when it is being dissolved in water. see the reaction below:

2Tl(s) + 2H2O(l) → 2TlOH(aq) + H2(g)

  • Since we all know it can be poisonous, but one thing is that it dissolves slowly only for Sulphuric acid.
