in naming a binary molecular compound, the number of atoms of each element present in the molecule is indicated by
oxygen is in the formula
what does an -ite or -ate ending in a polyatomic ion mean
nonmetallic elements
binary molecular compounds are made of two
a binary IONIC compound consist of a metal and a nonmetal, while a binary MOLECULAR compound consist of two nonmetallic elements
compare the compositions of binary ionic and binary molecular compounds
prefixes are used when writing the names of binary molecular compounds, such as carbon tetraccloride. The prefix tells how many atoms of an element are present in each molecule of the compound. You then write the symbol an dhte subscript according to the prefixes. Ex: CCl4
given the name of a binary molecular compound, describe how to write its formula. Use carbon tetrachloride as an example.
