Platinum Melting Point

The melting point of an element is the temperature at which it is converted from solid to liquid. Let us look into the melting point of platinum.

Platinum has a melting point of 2041.4 K, or 1768.30 C.

Platinum Boiling Point

The temperature at which an element’s vapour pressure equals that of the atmospheric pressure is its boiling point. Let’s talk about platinum’s boiling point.

The boiling point of platinum is 4098 K or 38250 C.

Platinum Vanderwaals Radius

Vanderwaals Radius is the half the distance between the centre of nuclei of two atoms held together by vanderwaal force. Let us study about the vanderwaals radius of platinum.

The vanderwaals radius of platinum is 175 pm. It is greater than its covalent radius.

Platinum Ionic or Covalent Radius

The covalent radius is half the distance between the centres of two covalently bound nuclei. Let us look into the ionic radius of platinum.

The Ionic or covalent radius of platinum is 136pm.

Isotopes of Platinum

Platinum Electronic Shell

The electrons present in an atom is filled in various electronic shells. Let us discuss about the electronic shell of platinum.

Platinum has six electronic shells. They are 2,8,18,32,17,1.

Platinum Energy for First Ionization

The amount of energy required to eject the most slackly held electron from an atom’s outermost shell is known as the ionisation energy.. Let us discuss about the first ionization energy of platinum.

Platinum has a first ionization energy value of about 870 KJ/mol. Since the most loosely held electron is far away from the nucleus it can be easily removed. So platinum has low first ionization energy.

Platinum Energy for Second Ionization

The energy needed to expel the electron from a monopositive ion is known as an element’s second ionisation energy.

The second ionization energy of platinum is found to be 1791 KJ/mol. Here the second electron is needed to be removed from the d orbital and it requires more amount of energy so that’s the reason for high second ionization energy for platinum.

Platinum Energy for third Ionization

The energy needed to expel an electron from a dipositive ion is an element’s third energy. Let us look into the third ionization energy of platinum.

There is no third ionization energy is found for platinum.

Platinum Oxidation States

The total number of electrons that the atom has gained or lost can be used to characterise its oxidation state. Let us discuss about the oxidation states of platinum.

Platinum has 10 oxidation States. They are -3, – 2 ,- 1, 0,+ 1,+ 2, + 3, + 4, + 5,+ 6.

Platinum Electronic Configuration

Electronic configuration is the arrangement of electrons of an atom in the various shells. Let us deal with the electronic configuration of platinum.

The electronic configuration of platinum is 4f14 5d9 6s1.

Allotropes is the existence of more than one chemical form of an element. Let us look into the allotrope of platinum.

There is no allotrope is found for platinum. It has only one solid form.

Platinum Chemical Classification

Chemical classification is the classification of an element dependent on the properties and electronic configuration. Let us look into chemical classification of platinum.

Platinum is a group d element or a transition metal where the last electron enters into the d orbital. Platinum belongs to group ten and period six of periodic table.

Platinum State at Room Temperature

The chemical state of an element is due to its electronic, physical and chemical properties. Let us look into the state of platinum at room temperature.

Platinum is a solid at room temperature.

Is Platinum Paramagnetic?

When an object has unpaired electrons, it is clearly a paramagnetic substance. Let us check whether platinum is paramagnetic or not.

Platinum is paramagnetic in nature. It is as a result of the unpaired electrons that are present there. 4f14 5d9 6s1 is the electrical configuration. Here there is a presence of unpaired electrons in both s and d orbital that indicate that it is paramagnetic in nature.

Conclusion

Platinum is a transition metal which is resistant to corrosion at even high temperature. It can cause numerous health issues when exposed to its salt. It is utilised in electrical contacts, electrodes, jewellery, and catalytic converters, among other things.
