Answer : The Lewis structure of
shows that the central phosphorus atom has 1 non-bonding and 3 bonding electron pair(s).
Explanation :
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 are shown by 'dot'.
The given molecule is, phosphorous trifluoride.
As we know that phosphorous has '5' valence electrons and fluorine has '7' valence electrons.
Therefore, the total number of valence electrons in phosphorous trifluoride,
= 5 + 3(7) = 26
According to electron-dot structure, there are 6 number of bonding electrons and 20 number of non-bonding electrons.
The Lewis structure of
shows that the central phosphorus atom has 1 non-bonding and 3 bonding electron pair(s).
The Lewis-dot structure of
is shown below.
