Yes, this is the ground state of magnesium.
The given configuration is belonging to the ground state of Mg.
The arrangement of electrons in atomic or molecular orbitals within an atom, molecule, or other physical structure is known as the electronic configuration. For instance, the neon atom's electron configuration is 1s2 2s2 2p6, which means that 1, 2, and 6 electrons, respectively, are present in each of the 1s, 2s, and 2p subshells.
According to electronic configurations, each electron moves individually within an orbital while being surrounded by an average field produced by all other orbitals. Slater determinants or configuration state functions are used to mathematically describe configurations.
Physicists and chemists use a common nomenclature to indicate the electron configurations of atoms and molecules. For atoms, the notation consists of a list of the labels for each atomic subshell, such as 1s, 2s, 2p, 3s, and 3p for phosphorus, with a superscript indicating how many electrons are assigned to each subshell. For instance, hydrogen's configuration is 1s1 because it possesses one electron in the first shell's s-orbital. Lithium's configuration is represented as 1s2 2s1 because it possesses one electron in the (higher-energy) 2s-subshell and two in the 1s-subshell.The chemical formula for phosphorus (atomic number 15) is 1s2 2s2 2p6 3s2 3p3.
