What is a covalent bond?

Back

A covalent bond is a type of chemical bond where electrons are shared between atoms to fill their outer electron shells.

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed between a metal atom and a nonmetal atom, characterized by the transfer of electrons from one atom to another.

What type of bond typically has a high melting point?

Back

Ionic bonds typically have high melting points due to the strong electrostatic forces between the charged ions.

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

How do ionic bonds form?

Back

Ionic bonds form when electrons are transferred from a metal atom to a nonmetal atom, resulting in the formation of positively and negatively charged ions.

What is the difference between ionic and covalent bonds?

Back

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

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 around.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where the electrons are shared unequally between the two atoms, resulting in a molecule with a slight charge.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.
