History of Teneso
Discoverer
This element was discovered by a joint team from the Central Institute for Nuclear Research in Dubná, Russia, and the National Laboratory in Tennessee, USA, known as Oak Ridge.
Where was the element teneso discovered?
It was discovered at Oak Ridge National Laboratory belonging to Vanderbilt University in Tennessee, United States; The Central Institute for Nuclear Research in Dubná was also involved in the discovery.
In what year was this element discovered?
In 2010, it was given the name Teneso because of where it was synthesized, at Oak Ridge National Laboratory in Tennessee, USA.
Properties
Atomic and physical properties
As an element of the periodic table belonging to group number 17, it is part of the group of halogens; group 17 is composed of 5 halogens, which are:
- Chlorine
- Bromine
- Fluorine
- Iodine
- astatine
Each of these elements gives rise to an ns2np5 Electron configuration and has 7 electrons in its valence shell; Time is believed to behave similarly to that exhibited by the halogens, mentioned above, in many ways.
The exact melting and boiling points of teneso are not known. This element has been given different values between 350-5000C and higher values such as 350-5500C and 6100C which exceed the values corresponding to all the other elements of the halogen group and including astatine. .
Over time, more studies were done, later revealing values that predict a boiling point of 3450C, making it similar to the value of astatine; In experimental cases, the values can be 5030C.
Chemical properties
Elements such as chlorine, bromine, fluorine, astatine and iodine use the octet rule to achieve a more stable electron configuration, in which they accept another electron, completing 8 electrons in their shell of valence and forming the Electron configuration of a noble gas.
When two atoms of Ununseptium (which is the systematic and temporary name given to Teneso before its final naming) come together, they are expected to form a diatomic molecule, since Teneso cannot only fulfill the rule of l octet by completing 8 electrons in its shell valence but also by the formation of covalent bonds.
oxidation states
The oxidation states of teneso are:
- -1 which is the most unstable.
- +5
- +3
- +1 this one being the most stable.
Characteristics of Teneso
- Symbol: Ts
- Number: 117
- Group: 17, known as the halogen group.
- Belonging to period 7, block p.
- Atomic mass: 294 u
- Condition: The condition of this element is unknown in its natural form, however it is considered solid.
- Appearance: The appearance of this item is unknown; it is thought to be probably dark in color,
- Metal considered highly radioactive and synthetic.
What uses can we give to teneso?
It is an element produced in controlled quantities and has only been used in the context of scientific research, so no other uses are known at this time.
Can it have harmful effects on health or even on the environment?
This element does not represent a great danger because it is not produced naturally, which is recommended to be careful when producing it (even in small quantities) because it is a very radioactive element and its bad handling fact It can be harmful to the health of the individual and cause damage to the environment.
That was all for today my chemistry minds, hope the info was helpful!!!
