7) Choose the statement that is TRUE. A) f electrons completely shield valence electrons from nuclear charge. B) Valence electrons partially shield one another from nuclear charge. C) Valence electrons experience the most shielding in an atom. D) According to Slater's Rules, shielding ranges from 0.3 to 1. E) Core electrons have the strongest attraction to the nucleus. F) All of the above are correct. ID: exal num Dept 8) Place the following in order from lowest to hightest metallic character. R6 G K Na A) K<Cs Na < Rb B) Na <K<Rb<CS c) Cs<K<Na <Rb D) Na < Rb <Cs<K E) Cs <Rb<K <Na F) K<Cs < Rb < Na fo You pro Tes 9) Which of the following statements is FALSE? Trai ans Sca imr A) Spin quantum number reflects the intrinsic angular momentum of an electron B) The electrons involved in bonding called valence electrons. C) Repulsion of one electron by other electrons is known as shielding. D) No two electrons in an atom can have the same four quantum numbers. E) An atom or ion that contains unpaired electrons is attracted to an external magnetic field F) Electrons have only one of spin or orbital angular momentum

Answer 1

shielding effect, describes the decrease in attraction between an electron and the nucleus in any atom with more than one electron shell. The more electron shells there are, the greater the shielding effect experienced by the outermost electrons.
