.2 Chem Unit 5 Review

Front

How many valence electrons are in Carbon?

Back

Carbon has 4 valence electrons.

Front

What type of bond is formed between Oxygen and Hydrogen?

Back

A polar bond is formed between Oxygen and Hydrogen.

Front

Which of the following elements must occur diatomic in elemental form?

Back

Iodine occurs diatomic in elemental form.

Front

What is a double bond in chemistry?

Back

A double bond is a type of chemical bond where two pairs of electrons are shared between two atoms.

Front

What is the Lewis Dot structure?

Back

The Lewis Dot structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

What is the octet rule?

Back

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

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 is a polar molecule?

Back

A polar molecule has a partial positive charge on one side and a partial negative charge on the other side due to unequal sharing of electrons.

Front

What are diatomic molecules?

Back

Diatomic molecules are molecules composed of only two atoms, which can be of the same or different chemical elements.

Front

What is the significance of the periodic table in chemistry?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.
