The electron configuration for boron is 1s22s22p1. If your periodic table doesn't agree with this, your answers for elements near the f -orbitals may be slightly different. 1) sodium 1s 2 2s 2 2p 6 3s 1 2) iron 1s 2 2s 2 Atomic # Symbol. Name.

Some people find it easier to use the periodic table as the “road map”: As you move through the elements in order by atomic number, you are moving through the sub-levels from lowest to highest energy. Now, the energy of the eigenstate of the hydrogen atom characterized by the quantum numbers n, l, m is E = E0 / n2, where the ground-state energy E0 is specified in Equation ( [e9.56] ). Hence, the energy of the photon emitted during a 2P → 1S transition is ℏω = E0 / 4 − E0 = − 3 4 E0 = 10.2eV. 1s 2 2s 2: boron: 5: 1s 2 2s 2 2p 1: carbon: 6: 1s 2 2s 2 2p 2: nitrogen: 7: 1s 2 2s 2 2p 3: oxygen: 8: 1s 2 2s 2 2p 4: fluorine: 9: 1s 2 2s 2 2p 5: neon: 10: 1s 2 2s 2 2p 6: sodium: 11: 1s 2 2s 2 2p 6 3s 1: magnesium: 12: 1s 2 2s 2 2p 6 3s 2: aluminum: 13: 1s 2 2s 2 2p 6 3s 2 3p 1: silicon: 14: 1s 2 2s 2 2p 6 3s 2 3p 2: phosphorus: 15: 1s 2 2s 2 2p 6 3s 2 3p 3: sulfur: 16: 1s 2 2s 2 2p 6 3s 2 3p 4: chlorine: 17: 1s 2 2s 2 2p 6 3s 2 3p 5: argon: 18: 1s 2 2s 2 2p 6 3s 2 3p 6 Potassium (K) atom has 19 electrons. The full electron configuration of Potassium (K) is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 1. The abbreviated form - [Ar]4s 1 - means the electron configuration of Argon (Ar), plus one electron in the 4s orbital.

Since everything up to the 6p 6 is the same electron configuration as the noble gas radon, The 2S is slightly lower in energy than the 2P's and thus fills first; the 2P's are all equal to each other in energy. The 2S orbital is shaped like a sphere; the three 2P's are each shaped like a dumbell, intersecting at their centers at right angles to each other. Sodium (Na) is the first element to use the third energy level. It follows from Equation ( [e13.128]) that the modulus squared of the dipole moment for the 2P → 1S transition takes the same value d2 = 215 310 (ea0)2 for m = 0, 1, or − 1. Clearly, the transition rate is independent of the quantum number m.
