Exploring Ionic Bond Formation

This video tutorial by Mr. Andersen covers the essentials of ionic bonding, contrasting it with covalent bonding. It explains how electrons are transferred between atoms, using sodium chloride as a primary example. The video details the formation of cations and anions, and how their charges affect ionic bonding. It introduces Coulomb's law to explain the stability of ionic solids and discusses lattice energy's role in determining the strength of ionic compounds. The tutorial concludes by connecting microscopic structures to macroscopic properties.

What is the main difference between ionic and covalent bonding?

• Covalent bonding involves transferring electrons.

• Ionic bonding involves sharing electrons.

• Ionic bonding involves transferring electrons.

• Covalent bonding involves losing electrons.

In the formation of sodium chloride, what happens to the electron from sodium?

• It is shared with chlorine.

• It remains with sodium.

• It is transferred to chlorine.

• It is lost to the environment.

What charge does a sodium ion have after losing an electron?

• Positive

• Neutral

• Negative

• No charge

What is the term used for a positively charged ion?

• Neutron

• Cation

• Proton

• Anion

What determines the strength of an ionic bond according to Coulomb's law?

• Both the charge and distance between the ions

• The charge of the ions

• The size of the ions

• The distance between the ions

What happens to lattice energy when the size of the ion decreases?

• It remains the same

• It fluctuates

• It decreases

• It increases

How does the size of the fluorine ion compare to the chlorine ion?

• Fluorine ion is neutral

• They are the same size

• Fluorine ion is smaller

• Fluorine ion is larger

What happens to lattice energy when the size of the ion increases?

• It fluctuates

• It remains the same

• It decreases

• It increases

What is the effect of increasing the charge on the lattice energy?

• It fluctuates

• It increases

• It remains the same

• It decreases

Which compound would have a higher lattice energy, sodium chloride or barium oxide?

• Neither have lattice energy

• Both have the same lattice energy

• Barium oxide

• Sodium chloride
