Write the formula for each molecular compound. a. phosphorus trichloride b. chlorine monoxide c. disulfur tetrafluoride

Verified step by step guidance

1. insert step 1> Identify the elements involved in the compound. In this case, the elements are chlorine (Cl) and oxygen (O).
2. insert step 2> Determine the prefixes used in the name of the compound. The prefix 'mono-' indicates one atom of the element it precedes.
3. insert step 3> Write the chemical symbol for chlorine, which is 'Cl'.
4. insert step 4> Write the chemical symbol for oxygen, which is 'O'.
5. insert step 5> Combine the symbols with the appropriate subscripts based on the prefixes. Since 'mono-' indicates one atom, the formula is ClO.

Key Concepts

Molecular Compounds

Molecular compounds are formed when two or more nonmetals bond together by sharing electrons. They are characterized by covalent bonds, which involve the sharing of electron pairs between atoms. The properties of molecular compounds, such as their state at room temperature and solubility, differ significantly from ionic compounds, which are formed from metal and nonmetal ions.

Naming Conventions

The naming of molecular compounds follows specific conventions, often using prefixes to indicate the number of atoms of each element present in the compound. For example, 'mono-' indicates one, 'di-' indicates two, and so forth. In the case of chlorine monoxide, the prefix 'mono-' is used for the single oxygen atom, while chlorine retains its elemental name.

Chemical Formulas

A chemical formula represents the composition of a compound using symbols for the elements and numerical subscripts to indicate the number of atoms of each element. For molecular compounds, the formula reflects the actual number of atoms in a molecule. In the case of chlorine monoxide, the formula is ClO, indicating one chlorine atom and one oxygen atom.
