Chemical Bonding Review

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.

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a nonmetal.

Front

What is a covalent bond?

Back

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

Front

How do you determine the number of valence electrons in an atom?

Back

The number of valence electrons can be determined by looking at the group number of the element in the periodic table.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What type of bond is formed between two nonmetals?

Back

A covalent bond is formed between two nonmetals.

Front

What is the chemical formula for aluminum oxide?

Back

The chemical formula for aluminum oxide is Al₂O₃.

Front

How many total atoms are in the compound Al₂O₃?

Back

There are 5 total atoms in the compound Al₂O₃ (2 Aluminum and 3 Oxygen).

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 slight charge difference.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of covalent bond where the electrons are shared equally between the two atoms.
