The pH scale measures how acidic a substance is. The pH scale ranges from 0 to 14.

Neutral value of pH scale is equal to 7.

If the pH is less than 7, then it is Acidic.

If pH is Greater than 7, then it is Basic.

Mercury is a liquid metal at room temperature. Basically, it is because Mercury is bad at sharing of electron since Mercury has a behavior of the valence electron. Mercury has a low melting point and furthermore, mercury is exceptionally poor electrical and thermal conductor and doesn't form diatomic molecules in the gas.

Symbol: Hg

Atomic number: 80

Melting point: -38.83 `C

Boiling point: 356.7 `C

Sir J.J Thomson had discovered the electron. It was the most powerful innovation of analytical invention in 1897. Thomson suggested that one of the Fundamental Unit was more than 1000 times smaller than an atom. This subatomic particle is currently known as the ‘Electron’. He did his experiment on the properties of Cathode rays.

J.J Thomson also discovered Isotope.

Inert Transition Elements belong to F block.

Inert transition elements include elements with Atomic Number 57-71, which are also known as Lanthanide and elements with Atomic Number from 89-103, which are considered Actinides.

There are four blocks in the Modern Periodic Table.

Total elements in the Periodic Table: 118

The first 94 elements occur naturally whereas elements from 95 to 118 have only been synthesized in Laboratories or through Nuclear reactors.

Ionic Bond also called as Electrovalent Bond. A Bond formed by the complete transfer of one or more electrons from one atom to another atom is called an Ionic bond, ex-NaCl.

Ionic bond has a high melting point and boiling point. They are bad conductor of electricity because their charge carriers cannot move through the Crystal.
