Short Answer

Expert verified
Question: Write the abbreviated ground state electron configurations for the following elements using the noble gas notation: (a) Phosphorus (P) (b) Arsenic (As) (c) Tin (Sn) (d) Zirconium (Zr) (e) Aluminum (Al) Answer: (a) P: [Ne]3s^2 3p^3 (b) As: [Ar]4s^2 3d^10 4p^3 (c) Sn: [Kr]5s^2 4d^10 5p^2 (d) Zr: [Kr]5s^2 4d^2 (e) Al: [Ne]3s^2 3p^1

Step by step solution

01

Identify noble gases for each element

Firstly, locate each element in the periodic table and determine the noble gas that precedes each element. Here are the noble gases for each element: (a) P (phosphorus) -> Ne (neon) (b) As (arsenic) -> Ar (argon) (c) Sn (tin) -> Kr (krypton) (d) Zr (zirconium) -> Kr (krypton) (e) Al (aluminium) -> Ne (neon)
02

Write electron configuration

Using the chosen noble gases, write the ground state electron configuration for each element in abbreviated form: (a) P -> [Ne]3s^2 3p^3 (b) As -> [Ar]4s^2 3d^10 4p^3 (c) Sn -> [Kr]5s^2 4d^10 5p^2 (d) Zr -> [Kr]5s^2 4d^2 (e) Al -> [Ne]3s^2 3p^1
