Chemistry / Elements and Compounds. Substances can be divided into pure substances and mixed substances. Pure substances can be further divided into elements and compounds.

Notice what the rule says: the maximum covalency of 2nd-period elements. It doesn't say for all elements in the 2nd period, but rather, when considering each element. Carbon is the atom that can make four bonds at once, e.g. in CH_4 and other hydrocarbons. Not fluorine. On the other hand, Br and I can make more than four bonds, as they can pool in (n-1)d orbitals to form hypervalent. chem 121 molecules, compounds, and chap 3 assign chemical equations write the best answer, including units when necessary, to each question on the appropriate line on the answer sheet. for true/false questions, write the word true or false on the answer sheet. clearly show all work on a separate sheet of paper
