Chapter 7: Q27 E (page 394)

Write the Lewis structure for the diatomic molecule \({{\rm{P}}_{\rm{2}}}\), an unstable form of phosphorus found in high temperature phosphorus vapor.

Short Answer

Expert verified

The Lewis structure for the diatomic molecule \({{\rm{P}}_{\rm{2}}}\) is:

Step by step solution

01

Define Chemical Bonding

A chemical bond is a long-term attraction between atoms, ions, or molecules that allows chemical compounds to form.

02

Writing the Lewis structure

(a) The first step is to figure out how many valence electrons there are. As there are two atoms in total, the total amount of valence electrons on each is.

(b) Next, we'll use a single bond to connect both. Due to both atoms using one electron to create a single connection, four valence electrons are left on each atom.

(c) However, each atom's octet is not fulfilled. As a result, both atoms will use their two additional electrons to create a triple bond.

Therefore, the Lewis structure is:
