Ionic & Covalent Bonding

Front

What is the definition of an ionic bond?

Back

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

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 type of elements typically form ionic bonds?

Back

Ionic bonds typically form between metals and nonmetals.

Front

What type of elements typically form covalent bonds?

Back

Covalent bonds typically form between nonmetals.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have eight valence electrons, achieving a stable electron configuration.

Front

What is the difference between a polar and nonpolar covalent bond?

Back

A polar covalent bond occurs when electrons are shared unequally between atoms, while a nonpolar covalent bond occurs when electrons are shared equally.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together by covalent bonds.

Front

What is the significance 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

What is a metallic bond?

Back

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

Front

What is an example of a molecule formed by covalent bonding?

Back

An example of a molecule formed by covalent bonding is water (H2O).
