Question

Enter the electron configuration for the ion most likely formed by phosphorus. Express your answer in the order of orbital filling as a string without blank space between orbitals. For example, the electron configuration of Li could be entered as 1s^22s^1 or [He]2s^1.

Answer 1

Answer:

1s2 2s2 2p6 3s2 3p6

Explanation:

Phosphorus is a non metal. It gains electrons to form ions. The most likely ion formed is the phosphide, where it gains three extra electrons.

Total number of electrons in Phosphide = 15 + 3 =18

The electronic configuration is given as;

1s2 2s2 2p6 3s2 3p6

Answer 2

Electronic Configuration can be defined as the electron distribution of an atom or molecule in an atomic or molecular orbit. The atomic orbit consists of the s, p and d orbitals.

The Atomic number of Phosphorus is 15.

Thus, the Electronic configuration of Phosphorus is 1s² 2s² 2p6 3s² 3p³.
