Bonding Re-test

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs when one atom transfers electrons to another atom, resulting in the formation of charged ions that attract each other.

Front

Which elements typically form ionic bonds?

Back

Elements that are metals and nonmetals, such as sodium and chlorine or magnesium and oxygen, typically form ionic bonds.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is the Lewis dot structure?

Back

The Lewis dot structure is a diagram that represents the valence electrons of atoms within a molecule, showing how they are arranged and bonded.

Front

How do you determine the molecular geometry of a molecule?

Back

Molecular geometry can be determined using the VSEPR (Valence Shell Electron Pair Repulsion) theory, which considers the repulsion between electron pairs around a central atom.

Front

What is the molecular geometry of water (H2O)?

Back

The molecular geometry of water is bent due to the two lone pairs of electrons on the oxygen atom.

Front

What type of bond conducts electricity when dissolved in water?

Back

Ionic bonds conduct electricity when dissolved in water because they dissociate into ions that can move freely.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the formation of charged ions, while covalent bonds involve the sharing of electrons between atoms.

Front

What is the significance of electronegativity in bond formation?

Back

Electronegativity is a measure of an atom's ability to attract electrons; it helps determine whether a bond will be ionic or covalent based on the difference in electronegativity between the bonded atoms.

Front

What is the bond formed between phosphorus and chlorine?

Back

The bond formed between phosphorus and chlorine is a covalent bond.
