The ground state is the lowest energy state of the atom. When the atom absorbs energy, it can move to a higher energy state, or excited state. 3. Under what circumstances can an atom emit a photon? A photon is emitted when an atom moves from an excited state to its ground state or to a lower-energy excited state. 4.
The ground-state electron configuration is the most basic and simplest way to represent the electrons of an element in the orbitals. It is also the most stable arrangement. A maximum number of electrons in each subshell is given by its degeneracy, 2(2l+1). Configuration Writing Practice 1. Write a ground state electron configuration for each neutral atom. Ground state means that all of the lowest possible energy levels (up to the proper number of electrons for the element) are filled. a) Na b) Pb c) Sr d) U e) N f) Ag g) Ti h) Ce i) Cl j) Hg 2.
Diagram of orbital energy levels in an one-electron atom (H) The fourth quantum number: electronic spin The spin quantum numenber s : describes the spin of the electron within that orbital. It can have two values: +1/2 and –1/2. Fondamental state } Excited states All orbitals having the same value of n (principal quantum number) have the same ... Sep 12, 2018 · The stability depends on the electron configuration of the atom. Figure 01: Arrangement of Electrons in Orbitals of Nitrogen Atom Moreover, if we consider the magnetic properties of a chemical element, there can be three major types of magnetism as diamagnetic, paramagnetic and ferromagnetic elements.
