Write the iupac name and symbol of the element with atomic number 119.

Explanation

The electronic configuration of boron atom in ground state and excited states are as follows:

Boron undergoes `sp^(3)` hybridisation. Out of four hybrid orbitals, two hybrid orbitals of each boror atom overlap with half filled Is orbital of the two hydrogen atoms. It forms covalent bonds.

Third half filled hybrid orbital of one boron atom and empty hybrid orbital of another boron atom overlap simultaneously with the half filled orbital of H-atom. Empty hybrid orbital is shown by dotted line. Thus, the bond formed is known as three centred electron pair bond and the shape of delocalised electron cloud formed is just like a banana. These bonds are called banana bonds.
