figure.4 has two models of CH5+ and text says first model has
valence of 6 which I don't understand.
according to equation above. shouldn't valence be
valence = 4-0=0 or valence=5+1(I'm not sure... because there
are one electron in hydrogen)=6??

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.
