What is the difference between core electrons and valence electrons? Why do we emphasize the valence electrons in an atom when discussing atomic properties? What is the relationship between valence electrons and elements in the same group of the periodic table?
Answer to relevant QuestionsThe periodic table consists of four blocks of elements that correspond to s, p, d, and f orbitals being filled. After f orbitals come g and h orbitals. In theory, if a g block and an h block of elements existed, how long ...Write the expected ground-state electron configuration for the following. a. The element with one unpaired 5p electron that forms a covalent compound with fluorine. b. The (as yet undiscovered) alkaline earth metal after ...Give possible values for the quantum numbers of the valence electrons in an atom of titanium (Ti). Explain why the first ionization energy tends to increase as one proceeds from left to right across a period. Why is the first ionization energy of aluminum lower than that of magnesium and the first ionization energy of ...Three elements have the electron configurations 1s22s22p63s23p6, 1s22s22p63s2, and 1s22s22p63s23p64s1. The first ionization energies of these elements (not in the same order) are 0.419, 0.735, and 1.527 MJ/ mol. The atomic ...
