Response
To determine the bond type (ionic or covalent) for each compound:
\( \ce{PH3} \)
- Step 1: Identify elements. \( \ce{P} \) (nonmetal) and \( \ce{H} \) (nonmetal).
- Step 2: Nonmetal-nonmetal bonds are covalent. So \( \ce{PH3} \) is covalent.
\( \ce{CaO} \)
- Step 1: Identify elements. \( \ce{Ca} \) (metal) and \( \ce{O} \) (nonmetal).
- Step 2: Metal-nonmetal bonds are ionic. So \( \ce{CaO} \) is ionic.
\( \ce{P2Br4} \)
- Step 1: Identify elements. \( \ce{P} \) (nonmetal) and \( \ce{Br} \) (nonmetal).
- Step 2: Nonmetal-nonmetal bonds are covalent. So \( \ce{P2Br4} \) is covalent.
\( \ce{NH3} \)
- Step 1: Identify elements. \( \ce{N} \) (nonmetal) and \( \ce{H} \) (nonmetal).
- Step 2: Nonmetal-nonmetal bonds are covalent. So \( \ce{NH3} \) is covalent.
\( \ce{MgBr2} \)
- Step 1: Identify elements. \( \ce{Mg} \) (metal) and \( \ce{Br} \) (nonmetal).
- Step 2: Metal-nonmetal bonds are ionic. So \( \ce{MgBr2} \) is ionic.
\( \ce{Li2S} \)
- Step 1: Identify elements. \( \ce{Li} \) (metal) and \( \ce{S} \) (nonmetal).
- Step 2: Metal-nonmetal bonds are ionic. So \( \ce{Li2S} \) is ionic.
\( \ce{SiO2} \)
- Step 1: Identify elements. \( \ce{Si} \) (nonmetal) and \( \ce{O} \) (nonmetal).
- Step 2: Nonmetal-nonmetal bonds are covalent. So \( \ce{SiO2} \) is covalent.
\( \ce{BF3} \)
- Step 1: Identify elements. \( \ce{B} \) (nonmetal) and \( \ce{F} \) (nonmetal).
- Step 2: Nonmetal-nonmetal bonds are covalent. So \( \ce{BF3} \) is covalent.
