A) How many core electrons and valence electrons make up a
carbon atom?Core electrons _______________Valance electrons _______________B) What kind of orbitals are carbon’s valence electrons in? (It
may be helpful to draw an orbital diagram.)

For each of the following main group elements, determine the
number of valence electrons an atom of that element has. Use
numerals (1, 2, 3, etc.), not words, to indicate the number of
valence electrons.
Calcium: _____________valence electrons
Carbon: _____________ valence electrons
Arsenic: _____________ valence electrons
Neon: ______________valence electrons

A Rydberg atom is an atom whose
valence electrons are in states with a very large principal quantum
number n. This means it has a probability cloud with a
large amplitude a large distance from the nucleus. Evidence of such
atoms has been detected by radio astronomers in the form of
radiation from diffuse hydrogen gas in intersellar space. In fact,
there is no theoritical limit on the size an atom can attain,
provided it is free from outside influences....
