Question

putting it all together
based on what you just learned, drag and drop the compounds into the chart as either ionic or covalent compounds:
*in ionic bonding metals their electrons to nonmetals so they all have 8.
*in covalent bonding nonmetals their electrons so they all have 8

Explanation:

Ionic compounds are formed when metals transfer electrons to non - metals. Covalent compounds are formed when non - metals share electrons.

• \(KCl\): \(K\) (metal) and \(Cl\) (non - metal), so it is ionic.
• \(N_{2}O_{5}\): \(N\) and \(O\) (both non - metals), so it is covalent.
• \(Fe_{2}O_{3}\): \(Fe\) (metal) and \(O\) (non - metal), so it is ionic.
• \(Cl_{2}\): \(Cl\) (non - metal), but it is a diatomic molecule of the same non - metal, not a compound formed by different non - metals sharing with a metal. However, if we consider the definition of covalent (sharing between non - metals), \(Cl_{2}\) has a covalent bond within the molecule. But since the task is about ionic vs covalent compounds (formed by different elements in most cases for the context of this problem), we focus on compounds formed by different elements.
• \(PH_{3}\): \(P\) and \(H\) (both non - metals), so it is covalent.
• \(SO_{2}\): \(S\) and \(O\) (both non - metals), so it is covalent.
• \(MgCl_{2}\): \(Mg\) (metal) and \(Cl\) (non - metal), so it is ionic.
• \(CuF_{2}\): \(Cu\) (metal) and \(F\) (non - metal), so it is ionic.
• \(Rb_{2}S\): \(Rb\) (metal) and \(S\) (non - metal), so it is ionic.
• \(SCl_{4}\): \(S\) and \(Cl\) (both non - metals), so it is covalent.
• \(CaF_{2}\): \(Ca\) (metal) and \(F\) (non - metal), so it is ionic.
• \(NaBr\): \(Na\) (metal) and \(Br\) (non - metal), so it is ionic.
• \(CS_{2}\): \(C\) and \(S\) (both non - metals), so it is covalent.
• \(CH_{3}Cl\): \(C\), \(H\), \(Cl\) (all non - metals), so it is covalent.

For the blanks:

• In ionic bonding, metals transfer their electrons to nonmetals so they all have 8 (electrons in the outer shell).
• In covalent bonding, nonmetals share their electrons so they all have 8 (electrons in the outer shell).

Answer:

Ionic Compounds: \(KCl\), \(Fe_{2}O_{3}\), \(MgCl_{2}\), \(CuF_{2}\), \(Rb_{2}S\), \(CaF_{2}\), \(NaBr\)
Covalent Compounds: \(N_{2}O_{5}\), \(PH_{3}\), \(SO_{2}\), \(SCl_{4}\), \(CS_{2}\), \(CH_{3}Cl\)
Blanks: transfer; share
