WebSummary: 2 p electrons are higher in energy than 2 s ones due to screening effects that result from electron-electron interactions. Explanations involving penetration of classical orbits or purely angular momentum … WebIn a B atom, a 1s electron has a greater Zeff than a 2s electron. Effective nuclear charge increases from left to right across a period on a periodic table. Across a period, as Zeff increases, atomic size increases. Effective nuclear charge does not depend on the number of electrons present in an atom.

WebAn electron in a 7s orbital has more energy than one in a 1s orbital because it is farther from the nucleus. it is surrounded by more electrons. its principle quantum number is higher. It actually has less energy because of inner-shell shielding. it is farther from the nucleus. WebThus, it is simple to determine the charge on such a negative ion: The charge is equal to the number of electrons that must be gained to fill the s and p orbitals of the parent atom. Oxygen, for example, has the electron configuration 1s 2 2s 2 2p 4, whereas the oxygen anion has the electron configuration of the noble gas neon (Ne), 1s 2 2s 2 2p 6.
