Chemical Bonding Flashcard

Front

What is 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.

What type of bonding occurs in water (H_2O)?

Back

Covalent bonding occurs in water.

Front

How many total atoms are present in 3 molecules of glucose (C_6H_{12}O_6)?

Back

There are 72 total atoms in 3 molecules of glucose.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.

Front

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 the difference between ionic and covalent compounds?

Back

Ionic compounds are formed by the transfer of electrons and consist of ions, while covalent compounds are formed by the sharing of electrons between atoms.
