Mountains of the British Isles and the Caledonian Mountains of
Scandinavia have the same rock composition as the Appalachian
Mountains. What does this tell us about the story of the past geology of
this part of Earth?

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
