Question

Which answer choices correctly describe properties of covalent compounds? Select all that apply.

Answer 1

Answer:

Explanation:

A covalent compound is made when two or more nonmetal atoms bond by sharing valence electrons. The shared valence electrons between two nonmetal atoms is called a covalent bond. Covalent bonds are formed when two atoms begin sharing electrons

Answer 2

Question:

Which answer choices correctly describe properties of covalent compounds?

Select all that apply.

The electrons in covalent compounds are less mobile than the electrons in ionic compounds.

Covalent compounds' bonds are weaker than ionic compounds' bonds when placed in water.

Electricity is easily conducted in covalent compounds.

Covalent compounds' bonds are not broken apart when placed in water.

Answer:

Two statements that describes are:  

• The electrons in covalent compounds are less mobile than the electrons in ionic compounds.

• Covalent compounds' bonds are not broken apart when placed in water.

Explanation:

Covalent compounds are non-metals that are bonded together. They are generally made up of two electrons which are shared by two atoms. These compounds are formed through sharing of electrons and ionic compounds are formed by transferring of electrons. Thus, electrons in the covalent compound are less mobile.

Covalent compounds break apart into molecules when dissolving in water because they are non-polar. Thus, when mixed in the water they don’t break apart rather form their own separate layer.
