What is the correct electron configuration of phosphorus
🔄 Click to see definition
Definition1/11
Phosphorus has an electron configuration of 1s2 2s2 2p6 3s2 3p3.
Another way to write that is [Ne] 3s2 3p3. The [Ne] represents the
fact that the beginning of phosphorus' electron configuration is
the same as Neon's.

🔄 Click to see definition
Definition1/11
The lone pair repels the electrons of the adjacent bonds more so
than does a bonding pair of electrons, so thus alters the molecular
geometry of the molecule.
