Some common features of squids and other mollusks include a soft body with a muscular foot, a mantle that secretes a shell (if present), and a radula for feeding. They also have a visceral mass containing organs such as the heart, digestive system, and reproductive organs. Additionally, mollusks possess a mantle cavity that houses the gills and functions in respiration. However, not all mollusks have all these features, as there is a wide diversity within the phylum.
Rn has 86 electrons, Th is the closest to having an atomic mass of 230
