This is a riddle. Whoever gets it right first gets a brainliest and 100 points. I ebb and flow freely through my rocky container although usually in one direction slowly. I have many exits but a single entrance from where I come. I am denser than most liquids. occasionally, my name changes and people run from me in terror.

What is my name?

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.

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.
