The use of carbon disulfide for extraction of fats, oils, andwaxeshas been largely discontinued in favour of other solvents that are less toxic and flammable. The use of carbon disulfide in making rayon and cellophane depends upon its reaction withcelluloseandcaustic sodato form colloidal solutions...
The carbon group elements (Group 14), with four electrons, occupy a middle position. Elements to the left of Group 14 have fewer than four electrons in the valence shell and tend to lose them (with their negative charges) to become positively charged ions, represented by the symbol for ...
