Question
Chapter 7, Problem 20QP
Interpretation Introduction
Interpretation:
The electron configuration for each given
Concept introduction:
The electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals.
Electron configurations describe each electron as moving independently in an orbital, in an average field created by all other orbitals.
The atomic number of a neutral atom is equivalent to the number of protons or electrons.
Aufbau's Principle states that the electrons are filled in the atomic orbital in the increasing order of their energy. Also, it gives the direction of the increasing
