Chemical Bonds Practice Flashcard

Front

What occurs in an ionic bond?

Back

Oppositely charged ions attract.

Front

What type of ions do elements on the LEFT side of the periodic table most likely form?

Back

Positive ions.

Front

What is a characteristic of ionic compounds in solid form?

Back

They are poor electrical conductors.

Front

What happens to ionic compounds when dissolved in water?

Back

They become strong electrical conductors.

Front

What type of bond has an unequal sharing of electrons?

Back

Polar covalent bond.

Front

In covalent bonds, how are valence electrons shared?

Back

They are shared, but attracted to the element with the higher electronegativity.

Front

What is the difference between polar covalent and nonpolar covalent bonds?

Back

Polar covalent bonds have unequal sharing of electrons, while nonpolar covalent bonds have equal sharing.

Front

What type of bond involves the transfer of electrons from one atom to another?

Back

Ionic bond.

Front

What is electronegativity?

Back

The tendency of an atom to attract electrons in a bond.

Front

What type of bond is formed between two nonmetals?

Back
