Question
molecular compounds
non - metal atoms can share electrons with other non - metal atoms including hydrogen. this is how molecular compounds are formed.
table 2.3 lists some examples of common molecular compounds.
molecular compounds have the following properties:
. they may be solids, liquids, or gases at room temperature.
. they have lower melting points than ionic compounds.
. they do not conduct electric current when they are melted or dissolved in water, except in the case of certain acids.
- identify the types of atoms in each compound. then state whether each compound is ionic or molecular. use the periodic table to help you. (you do not have to know the names of these compounds or their properties to do this.)

- what type of elements combine to form ionic compounds?
- what type of elements combine to form molecular compounds?
Step1: Recall element - type rules
Metals are on the left - hand side and middle of the periodic table, non - metals on the right. Ionic compounds form between metals and non - metals, molecular compounds between non - metals.
Step2: Analyze $MgBr_2$
$Mg$ (magnesium) is a metal, $Br$ (bromine) is a non - metal. So it is an ionic compound. Types: metal (Mg), non - metal (Br).
Step3: Analyze $PH_3$
$P$ (phosphorus) and $H$ (hydrogen) are non - metals. So it is a molecular compound. Types: non - metal (P), non - metal (H).
Step4: Analyze $P_4O_{10}$
$P$ (phosphorus) and $O$ (oxygen) are non - metals. So it is a molecular compound. Types: non - metal (P), non - metal (O).
Step5: Analyze $NaI$
$Na$ (sodium) is a metal, $I$ (iodine) is a non - metal. So it is an ionic compound. Types: metal (Na), non - metal (I).
Step6: Analyze $SiF_4$
$Si$ (silicon) and $F$ (fluorine) are non - metals. So it is a molecular compound. Types: non - metal (Si), non - metal (F).
Step7: Analyze $Ag_3P$
$Ag$ (silver) is a metal, $P$ (phosphorus) is a non - metal. So it is an ionic compound. Types: metal (Ag), non - metal (P).
Step8: Analyze $O_2F_2$
$O$ (oxygen) and $F$ (fluorine) are non - metals. So it is a molecular compound. Types: non - metal (O), non - metal (F).
Step9: Analyze $C_8H_{18}$
$C$ (carbon) and $H$ (hydrogen) are non - metals. So it is a molecular compound. Types: non - metal (C), non - metal (H).
| Chemical Formula | Types (metal or non - metal) | Ionic or molecular |
|---|---|---|
| $PH_3$ | Non - metal (P), Non - metal (H) | Molecular |
| $P_4O_{10}$ | Non - metal (P), Non - metal (O) | Molecular |
| $NaI$ | Metal (Na), Non - metal (I) | Ionic |
| $SiF_4$ | Non - metal (Si), Non - metal (F) | Molecular |
| $Ag_3P$ | Metal (Ag), Non - metal (P) | Ionic |
| $O_2F_2$ | Non - metal (O), Non - metal (F) | Molecular |
| $C_8H_{18}$ | Non - metal (C), Non - metal (H) | Molecular |
