Electrons in an s orbital are more effective than those in other orbitals at shielding other electrons from the nuclear charge. Effective nuclear charge increases from left to right across a period on the periodic table. Across a period, as Z increases, atomic size increases, Effective nuclear charge does not depend on the number of electrons present in an atom. In a N atom, a ls clectron has a greater Za than a 2s electron. Als electron in a B atom has a smaller Z than a ls election in a lB

A metallic element reacts vigorously with water, evolving hydrogen gas. An excited atom of this element has its outer electron in the 3p orbital. When this electron drops to its ground state in the 3s orbital, light is emitted of wavelength 589 nm What is the identity of the element? Explain how you arrived at your answer. What is the color of the emitted light?

The energies of the orbitals in many elements have been determined. For the first two periods they have the following values: (a) Why do the orbital energies generally become more negative on proceeding across the second period? (b) How are these values related to the ionization energy and electron attachment enthalpy of the elements? (c) Use these energy values to explain the observation that the ionization energies of the first four second-period elements are in the order Li Be B C. (Data from J. B. Mann, T. L Meek, and L C. Allen: Journal of the American Chemical Society, Vol. 122, p. 2780. 2000.)
One bit of evidence that the quantum mechanical model is correct lies in the magnetic properties of matter. Atoms with unpaired electrons are attracted by magnetic fields and thus are said to exhibit pararamagnetism. The degree to which this effect is observed is directly related to the number of unpaired electrons present in the atom. Consider the ground-state electron configurations for Li, N, Ni, Te, Ba, and Hg. Which of these atoms would be expected to be paramagnetic, and how many unpaired electrons are present in each paramagnetic atom?
What main group in the periodic table has elements with the largest electron affinities for each period? What group of elements has only unstable negative ions?
