Question

Write the electron configurations of P and Cl using both spdf and orbital box diagrams.

Answer 1

Answer:

Explanation:

Here, we want to write the electronic configurations for the given atoms

Spdf Notation:

Here, we start by knowing the atomic number of the atoms. The atomic number is the same as the number of electrons for an electrically neutral atom

For Phosphorus:

The number of electrons is 15

We have the spdf notation as follows:

$1s^2\text{ 2s}^2\text{ 2p}^6\text{ 3s}^2\text{ 3p}^3$

For Chlorine, the number of electrons is 17

We have the spdf notation as follows:

$1s^2\text{ 2s}^2\text{ 2p}^6\text{ 3s}^2\text{ 3p}^5$

Orbital Diagram:

For the orbital diagram, we simply fill in the orbitals as shown in the spdf notation

Each subshell contains 2 maximum number of electrons of opposite spin

For Phosphorus, we have it that:

For Chlorine, we have it that:
