Chemical bonds

Front

What is a chemical bond?

Back

A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds. It involves the sharing or transfer of electrons.

Front

What are the two main types of chemical bonds?

Back

The two main types of chemical bonds are ionic bonds and covalent bonds.

Front

What is an ionic bond?

Back

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

Front

What is a covalent bond?

Back

A covalent bond is formed when two atoms share one or more pairs of electrons.

Front

What is the role of valence electrons in bonding?

Back

Valence electrons are the outermost electrons of an atom and are involved in forming bonds with other atoms.

Front

How do ionic bonds affect the stability of elements?

Back

Ionic bonds make elements more stable by allowing them to achieve a full outer electron shell.

Front

What happens to an atom with one valence electron when it bonds?

Back

An atom with one valence electron is more likely to lose that electron to achieve a full outer shell.

Front

What is the difference between polar and non-polar covalent bonds?

Back

Polar covalent bonds involve unequal sharing of electrons, while non-polar covalent bonds involve equal sharing of electrons.

Front

What is a metallic bond?

Back

A metallic bond is a type of bond that occurs between metal atoms, where electrons are shared in a 'sea of electrons' allowing for conductivity.

Front

What is the significance of electron transfer in ionic bonding?

Back

Electron transfer in ionic bonding leads to the formation of ions, which are attracted to each other due to opposite charges.
