• nonmetal & nonmetal

• metalloid & metalloid

Covalent compounds are made up of...

• metal & metal

• metal & nonmetal

• nonmetal & nonmetal

• metalloid & metalloid

Ionic bonds result due to a _______ difference in electronegativity and covalent bonds result due to a ________ difference in electronegativity.

• large, small

• small, large

• medium, small

• small, medium

Electrons in an ionic bond are ___________ while electrons in a covalent bond are ___________

• shared, transferred

• transferred, shared

• shared, removed

• removed, shared

Covalent compounds are...

• solids

• gases

• all of the above

In order to name ionic compounds you name them...

• "as is"

• with prefixes

• with suffixes

• how you want to

In order to name covalent compounds you name them...

• "as is"

• with prefixes

• with suffixes

• how you want to

MgCl₂

• monomagensium dichloride

• magnesium dichloride

• magnesium chloride

• magnesium chlorine

Answer explanation

This is an ionic compound

Mg: metal

Cl: nonmetal

Name it "as is" with the full name of the metal and the -ide ending of the nonmetal

P₃Cl₈

• triphosphorous octachloride

• phosphorus octachlorine

• phosphorus chloride

• phosphorus chlorine

Answer explanation

P₃Cl₈ is a covalent compound

P=nonmetal

Cl=nonmetal

Covalent compounds are named using greek prefixes to indicate the subscript

3=tri

8=octa
