Please help! Most elements' names end in the suffix -ium. This practice started around the year 1800, with many elements discovered before that having a more common name. However, some elements are more recently discovered and don't end in -ium. Do you notice any patterns for these elements? Brainliest is up for grabs!

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.

here are some of the ways in which chemical and nuclear reactions differ.
