الخصائص الكيميائية تينيسين (25 حقيقة يجب أن تعرفها)


Tennessine is a chemical element that is observed as one of the heaviest semi metallic element. Let us discuss more facts about tennessine in details below.

Tennessine is known to be a synthetic element with very short lifetime due to its heavy form. It is also known as the second heaviest element among all. It is also called as the penultimate element as electrons are filled subsequently in the penultimate shells following Hund’s rule and Aufbau’s principle.

Tennessine is produced artificially from nuclear reactions from unequal nuclei which is expensive. Let us learn properties like density, weight, block about tennessine below.

Tennessine symbol

The atomic symbol or chemical symbol of tennessine is Ts named after Tennessee region as it was founded in universities by scientists in that region.

Atomic symbol of tennessine with atomic number and mass number on extreme bottom left and top left.

Tennessine group in periodic table

Tennessine belongs to group 17 of the periodic table. Group 17 generally has 7 valence electrons and it is called a halogen family.

Tennessine period in periodic table

Tennessine is a 7th period element in the periodic table. It occupies the last period from halogen family due to the most expanded electronic shell.

Tennessine block in periodic table

Tennessine is a p-block element as observed from its electronic configuration. The last electron gets filled in the 7p shell making it a p block element.

Tennessine atomic number

The atomic number of tennessine is 117. It has 117 protons in the nucleus of Ts and 117 electrons to neutralize the positively charged protons.

Tennessine atomic weight

The atomic weight of tennessine is 294 amu ( atomic mass unit ). The number of neutrons can be calculated using Mass No. – Atomic No. = 294 – 117 = 177 neutrons in Ts.

Tennessine Electronegativity according to Pauling

The electronegativity of tennessine according to Pauling scale has not yet been estimated as Ts is extremely unstable with a very short lifetime.

Tennessine atomic Density

The atomic density of tennessine is 7.3 g/cm3. It has higher density than water due to its large size and well packed crystal structure.

Tennessine melting point

The melting point of Tennessine is in between 350-550 0C. It requires heat in this range to undergo phase transformation from solid to liquid.

Tennessine boiling point

The boiling point of Tennessine is in the range of 610 0C. Ts requires heat as high as this to be in equilibrium between liquid and gaseous state.

Tennessine Van der waals radius

The Van der Waals radius of tennessine is not yet estimated but its atomic radius is estimated to be 138 pm empirically.

Tennessine ionic/covalent radius

The ionic or covalent radius of tennessine is measured to be in between 156 to 157 pm obtained by extrapolating the graph. It is greater than atomic radius.

Tennessine isotopes

Isotopes are chemical elements originating with same atomic number but different mass number. Let us check if Ts has its isotopic forms.

Tennessine has two isotopic forms differing only by the number of neutrons present in their respective nucleus. Ts isotopes with its half lives, decay mode and abundance is listed below.

Tennessine electronic shell

Electronic shell is a chemical representation in scientific manner about how the electrons present in an element are distributed accordingly in the orbits. Let us discuss below.

The electronic shell of tennessine is 2, 8, 18, 32, 32, 18, 7. The last orbit takes up only 7 electrons as it should be from its group name, 17.

Tennessine energy of first ionization

The first energy of ionization of Tennessine 742.9 kJ/mol.  The first electron will be removed from the 7s shell when Ts is in gaseous state.

Tennessine energy of second ionization

The second energy of ionization of Tennessine is 1435.4 kJ/mol. The second energy is higher than the first one as the Zممثل المؤسسة.

Tennessine energy of third ionization

The third energy of ionization of tennessine is 2161.9 kJ/mol. This is the highest among the 3 as Zممثل المؤسسة is greatest with high electrostatic forces of attraction.

Tennessine CAS number

The CAS number of tennessine is 54101-14-3 which is unique for only Ts to find about its structural properties and other facts during database search.

Tennessine ChemSpider ID

The ChemSpider ID of tennessine has not yet been found as less discovery is made due to its unstable nature.

Tennessine allotropic forms

Allotropes are chemical substances that exist in same physical state with different chemical properties. Let us check if Ts has its allotropic forms below.

 The allotropic forms of tennessine has not been discovered yet due to the heavy form with short lifetime.

Tennessine chemical classification

The chemical classification of tennessine is given below

  • Tennessine is a synthetic heavy element.
  • Tennessine is a halogen.
  • Tennessine has short lifetime with alpha decay mode to smaller units.

Tennessine state at room temperature

Tennessine is found to exist in الحالة الصلبة in semi metallic form due to its heavy form with high density and excess electron forms metallic bonding.

Is Tennessine paramagnetic?

Paramagnetic is a character observed in paramagnetic materials that has unpaired electrons or dipoles that is attractive to external magnetic field. Let us check below.

Tennessine is a paramagnetic as it has one unpaired electron the 7p shell that can align its magnetic dipole to the external المجال المغنطيسي to show magnetism.
