Type the chemical symbol for the following elements and classify them as a representative, transition, noble gas, or inner transition element. Note: an element may be classified in more than one way. Choose the most specific answer if there is more than one possible answer. a) 1s22s22p63s23p64s23d7 symbol: classification: b) 1s22s22p63s23p6 symbol: classification: c) 1s22s22p63s23p64s23d104p5 symbol: classification: d) On a piece of paper draw the orbital diagram of the atom whose electron configuration is shown in part c). Answer the following questions by looking at the orbital diagram: i) How many valence electrons are present? ii) How many unpaired electrons are present

d) On a piece of paper draw the orbital diagram of the atom whose electron configuration is shown in part c). Answer the following questions by looking at the orbital diagram:
i) How many valence electrons are present?
ii) How many unpaired electrons are present
s,p,d,f denotes the orbitals where electron fills up from lower energy orbital to higher energy orbital. At first, one electron enters in each of the orbitals, after being half-filled pairing takes place.
