Question

electronic configuration of the element 15​

Answer 1

Answer:

When we write the configuration we'll put all 15 electrons in orbitals around the nucleus of the Phosphorus atom. In writing the electron configuration for Phosphorus the first two electrons will go in the 1s orbital. ... Therefore the Phosphorus electron configuration will be 1s22s22p63s23p3.
