SF2
a. SF2: Sulfur difluoride
b. MgF2: Magnesium fluoride
c. SnCl2: Tin (II) chloride
d. PF5: Phosphorus pentafluoride
e. NO2: Nitrogen dioxide
f. SnO2: Tin (II) oxide
To name each of the following ionic compounds or binary molecules, you will need to determine the chemical formulas for the compounds first.
a. SF2: Sulfur difluoride
In this compound, sulfur (S) combines with two fluorine (F) atoms. Since fluorine is a halogen, it forms a covalent bond with sulfur. Therefore, the compound is a binary molecule.
b. MgF2: Magnesium fluoride
In this compound, magnesium (Mg) combines with two fluorine (F) atoms. Magnesium is a metal, and fluorine is a halogen, so magnesium forms a cation with a +2 charge (Mg2+), and each fluorine atom forms an anion with a -1 charge (F-). The charges balance out, resulting in an ionic compound. Therefore, the compound is an ionic compound.
c. SnCl2: Tin (II) chloride
In this compound, tin (Sn) combines with two chlorine (Cl) atoms. Tin can form multiple cations, but in this case, it has a +2 charge (Sn2+). Therefore, the compound is an ionic compound.
d. PF5: Phosphorus pentafluoride
In this compound, phosphorus (P) combines with five fluorine (F) atoms. Phosphorus can also form multiple cations, but in this case, it has a +5 charge (P5+). Therefore, the compound is an ionic compound.
e. NO2: Nitrogen dioxide
In this compound, nitrogen (N) combines with two oxygen (O) atoms. Both nitrogen and oxygen are nonmetals, so they form a covalent bond. Therefore, the compound is a binary molecule.
f. SnO2: Tin (II) oxide
In this compound, tin (Sn) combines with two oxygen (O) atoms. Tin can form multiple cations, but in this case, it has a +2 charge (Sn2+). Therefore, the compound is an ionic compound.
