Mg atom consists of 12 electrons with the electronic configuration as 2, 8, 2 . Q: Write the ground state electron configuration of each of the following atoms. This causes the magnetic fields of the electrons to cancel out; thus there is no net magnetic moment, and the atom cannot be attracted into a magnetic field. I. A. Rb + B. Atoms and ions that have the same electron configuration are said to be isoelectronic. Precipitation of the carbonate ion with barium ion 4. precipitation of the . What is the electron configuration for a nitride ion? explain? . Arrange them in order of increasing radius: rb+, y3+, se2-, br-, sr2: compare the elements na, o, mg and p. place the elements in order of increasing.
