Properties of Bonding Assessment

Select the false statement regarding the properties of bonding. [IPC.3C]

• Some metals readily lose one electron in order to attain an octet and form ionic bonds with nonmetals.

• Noble gases are not reactive and, typically, do not form bonds.

• Highly reactive nonmetals form ionic bonds with metals and covalent bonds with other nonmetals.

• Metals form covalent bonds with other metals.

Covalent bonds are formed when valence electrons are shared. Which element combinations demonstrate a covalent bond? Select TWO correct answers.

• Fr and Es

• Na and S

• P and Cl

• H and O

• Br and Mg

Consider the process of dissolution. Which statement correctly describes the dissolution of silicon in a solvent?

• Silicon dissolves in a solvent, forming a solution that is placed in group 4A, period 3.

• Silicon dissolves in a solvent, forming a solution that is placed in group 4A, period 2.

• Silicon dissolves in a solvent, forming a solution that is placed in group 2A, period 4.

• Silicon dissolves in a solvent, forming a solution that is placed in group 3A, period 4.

A metallic bond occurs between -

• One metal and one electron.

• One metal and one nonmetal.

• Two metals.

• Two nonmetals.

Which family tends to gain two electrons during a reaction?

• Oxygen family

• Alkali metals

• Noble gases

• Halogens

Given the atomic structure of Potassium (K), what can be predicted about its bonding? [IPC.4A]

• Potassium (K) is a highly reactive metal and will bond easily with another element because it has one valence electron to give up and become stable.

• Potassium (K) is a nonreactive metal and will not bond easily with another element because it has three valence electron orbitals.

• Potassium (K) is a nonreactive metal and will not bond easily with another element because it has a full valence electron orbital.

• Potassium (K) is a highly reactive metal and will bond easily with another.

Aluminum bonds with bromine to form AlBr₃. What happens to aluminum electrons? [Ipc-3A] Select one:

• The electrons are shared between aluminum and bromine.

• Aluminum will not bond with bromine.

• Aluminum gains electrons from bromine.

• Aluminum loses its electrons to bromine.

This Lewis dot structure could represent an atom for which of the following elements?

• B

• Si

• N

• Li

A student was making an aqueous solution using salt and water. Which of the following descriptions best explains the process of making the aqueous solution?

• Adding salt to the water makes the water more diluted.

• The water is the solute that dissolves into the salt that is acting as the solvent.

• The water is the solvent that dissolves into the salt that is acting as the solute.

• Salt will not dissolve into the water, and the salt will sink to the bottom of a container.

Which image best illustrates the dissolution process of a solute in water, resulting in the most concentrated solution?

• a.

• b.

• c.

• d.
