The standard state of phosphorus at 25∘C25∘C is P4P4. This molecule has four equivalent PP atoms, no double or triple bonds, and no expanded octets. Draw its Lewis structure.

Answer : The Lewis structure of is shown below.

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.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The representation of valence electrons of an atom by dots around the symbol of an element is said to be the Lewis-dot symbol.

In the representation of Lewis-symbol, one electron dot must put on each side of the element symbol then paired the electrons.

The given molecule is,

As we know that phosphorous has '5' valence electrons.

Therefore, the total number of valence electrons in = 4(5) = 20

According to Lewis-dot structure, there are 14 number of bonding electrons and 6 number of non-bonding electrons.

the pseudoscience are like beliefs, theories, or like practices that are considered scientific
