What is a pi bond?

Back

A pi bond is a type of covalent bond that is formed when two lobes of one involved atomic orbital overlap with two lobes of another in such a way that a region of electron density is formed above and below the line connecting the nuclei of the bonding atoms.

Front

Which molecule contains no pi bond?

Back

H2O (water) contains only sigma bonds.

Front

What type of bond is formed between two nonmetals?

Back

Covalent bond.

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, characterized by a 'sea of electrons' that are free to move, allowing for conductivity.

Front

What is resonance in chemistry?

Back

Resonance is a phenomenon where a molecule can be represented by two or more valid Lewis structures, indicating that the actual structure is a hybrid of these forms.

Front

Which molecule exhibits resonance?

Back

O3 (ozone) exhibits resonance.

Front

What is a chemical bond?

Back

A chemical bond is the force of attraction between atoms that holds them together as a stable molecule.

Front

What type of bond is likely to conduct electricity in solid form?

Back

Ionic bonds typically do not conduct electricity in solid form, but metallic bonds do.

Front

What elements generally compose an ionic bond?

Back

An ionic bond is generally formed between metals and nonmetals.

Front

What is the difference between covalent and ionic bonds?

Back

Covalent bonds involve the sharing of electrons between nonmetals, while ionic bonds involve the transfer of electrons from metals to nonmetals.
