Unit 5 Review

Front

How are ionic bonds formed?

Back

Ionic bonds are formed through the transfer of electrons from one atom to another.

Front

How many valence electrons does Oxygen (O) have?

Back

Oxygen has 6 valence electrons.

Front

NH3 is a (n) ____________ compound.

Back

NH3 is a covalent polar compound.

Front

Put the following in order of increasing ionization energy: Strontium, Aluminum, Indium.

Back

The order of increasing ionization energy is Strontium, Indium, Aluminum.

Front

An atom of Neon complies with the Octet Rule because it has ___ electrons in its outer shell.

Back

Neon has 8 electrons in its outer shell.

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 8 electrons.

Front

Define covalent bond.

Back

A covalent bond is a chemical bond formed by the sharing of electrons between two atoms.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

What is a polar covalent bond?

Back

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