WebIn a Be atom, a 1s electron has a greater Z eff than a 2s electron. Across a period, as Z eff increases, atomic size decreases. Electrons in a p orbital are more effective than those in other orbitals at shielding other electrons from the nuclear charge. A 1s electron is a Be atom has a smaller Z eff than a 1s electron in a Li atom. WebA greater nuclear charge will result in a greater attraction to the 1s electrons, and therefore more energy will be required to remove those electrons. Question 8 120 seconds Q. A sample containing atoms of C and F was analyze using x-ray photoelectron spectroscopy.

WebHydrogen has just one electron, so it has a single spot in the 1s 1s orbital occupied. This can be written out in a shorthand form called an electron configuration as 1s^ 1 1s1, where the superscripted 1 refers to the one electron in the 1s 1s orbital. Helium has two electrons, so it can completely fill the 1s 1s orbital with its two electrons.
