Answer : The correct representation of Lewis-dot structure for 5A element, Arsenic is shown below.
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
The number of valence electrons shown by 'dot'.
The given molecule is, Arsenic
The atomic number of arsenic = 33
As we know that the number of electrons is equal to the number of atomic number.
So, the number of electrons = 33
The electronic configuration of arsenic is, [tex][Ar]3d^{10}4s^24p^3[/tex]
The number of valence electrons present in arsenic = 5
The Lewis-dot structure of arsenic is shown below.
