Question

classify the following substances as an ionic compound or a covalent compound. select the single best answer. compound types of compound ch4 covalent ionic rbcl covalent ionic bf3 covalent ionic bacl2 covalent ionic sro covalent ionic

Explanation:

Step1: Recall compound - type rules

Ionic compounds usually form between metals and non - metals. Covalent compounds form between non - metals.

Step2: Analyze CH₄

Carbon and hydrogen are non - metals. So, CH₄ is covalent.

Step3: Analyze RbCl

Rubidium (Rb) is a metal and chlorine (Cl) is a non - metal. So, RbCl is ionic.

Step4: Analyze BF₃

Boron (B) and fluorine (F) are non - metals. So, BF₃ is covalent.

Step5: Analyze BaCl₂

Barium (Ba) is a metal and chlorine (Cl) is a non - metal. So, BaCl₂ is ionic.

Step6: Analyze SrO

Strontium (Sr) is a metal and oxygen (O) is a non - metal. So, SrO is ionic.

Answer:

CH₄: covalent
RbCl: ionic
BF₃: covalent
BaCl₂: ionic
SrO: ionic
