2 Estimate the approximate Zeff felt by a valence electron of carbon and oxygen. Assume that the shielding of electrons within the same shell is negligible. C: O:
The shielding of electrons gives rise to an effective nuclear charge, Zeff which explains why boron is larger than oxygen. Estimate the approximate Zeff felt by valence electron of boron and oxygen, respectively?A. +5 and +8B. +3 and +6C. +5 and +6D. +3 and +8E. +1 and +4
Estimate the approximate Zeff felt by an electron in the 3s orbital of Mg. Estimate the approximate Zeff felt by an electron in the 2p orbital of Mg. (Use approximation, not Slater's rule)
calculate the Zeff for the valence electrons in the atoms Li to Ne using (a) the assumption that shielding constant equals the number of inner shell electrons and (b) Slater's rules. Plot both sets of results on the same graph and discuss.
Arrange Se, K, and Ga in terms of increasing Zeff values acting on a valence electron. Assume that the valence electrons contribute nothing to the Zeff values. (Use the appropriate <, =, or > symbol to separate substances in the list.)
Calculate the Zeff for the valence electrons in the atoms Li to Ne using (a) the assumption that o equals the number of inner-shell electrons and (b) Slater's rules. Plot both sets of results on the same graph and discuss.
QUESTION 8 The effective nuclear charge felt by a valence electron in an atom is less than the atom's actual nuclear charge only when valence electrons are in the excited state. because core electrons are closer to the nucleus than the valence electrons. because valence electrons are more attracted to each other than the core electrons. o because core electrons partially shield the valence electrons from the charge of the nucleus.
In the Cr6+ cation, what is the effective charge felt by a valence electron? In the Ga+ cation, in its ground state, how many electrons have ml = +1 ?
Part A) What value do you estimate for Zeff experienced by the outermost electron in both Na and K by assuming core electrons contribute 1.00 and valence electronscontribute 0.00 to the screening constant?Part B) What values do you estimate for Zeff using Slater's rules?Part C) Which approach gives a more accurate estimate of Zeff ?1. The first method.2. The second (Slater) method.Part D) Does either method of approximation account for the gradual increase in Zeff that occurs upon moving down...
