Exam Day Review

Front

What type of bonding can be described as 'I give, I get'?

Back

Ionic bonding is characterized by the transfer of electrons from one atom to another, resulting in the formation of charged ions.

Front

What is the formula to calculate density?

Back

Density = Mass / Volume.

Front

What is the density of a substance if a bar of copper has a mass of 216g and a volume of 24cm³?

Back

The density of copper is 8.9g/cm³.

Front

Identify the type of bond in the compound CF₄.

Back

CF₄ is a covalent compound, formed by the sharing of electrons between carbon and fluorine.

Front

What is a bond between a metal and a nonmetal called?

Back

An ionic bond.

Front

If an atom of oxygen has a charge of -2, how many electrons does it have?

Back

An atom of oxygen with a -2 charge has 10 electrons.

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 is an ionic bond?

Back

An ionic bond is formed when one atom donates an electron to another atom, resulting in the attraction between oppositely charged ions.

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 the significance of the octet rule in bonding?

Back

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