Question

check
classify each of these compounds as ionic
nabr
sf₆
cobr₂
of₂
no₂

Explanation:

• NaBr: Sodium (Na) is a metal and bromine (Br) is a non - metal. Ionic compounds are formed between metals and non - metals. So, NaBr is ionic.
• SF₆: Both sulfur (S) and fluorine (F) are non - metals. Covalent compounds are formed between non - metals. So, SF₆ is covalent.
• CoBr₂: Cobalt (Co) is a metal and bromine (Br) is a non - metal. Ionic compounds are formed between metals and non - metals. So, CoBr₂ is ionic.
• OF₂: Both oxygen (O) and fluorine (F) are non - metals. Covalent compounds are formed between non - metals. So, OF₂ is covalent.
• NO₂: Both nitrogen (N) and oxygen (O) are non - metals. Covalent compounds are formed between non - metals. So, NO₂ is covalent.

Answer:

NaBr: Ionic
SF₆: Covalent
CoBr₂: Ionic
OF₂: Covalent
NO₂: Covalent
