What is the electron configuration of ground-state neutral magnesium (Mg)? - Correct
Answer 1s22s22p63s2
Mg has an atomic number of 12 on the periodic table. This means that ground-state
neutral Mg has 12 protons and 12 electrons. These 12 electrons are assigned to orbitals
in the order represented by the arrangement of the s-block and p-block on the periodic
table: 1s22s22p63s2.
