What is an Ionic Compound?!?

This video tutorial explains how to identify ionic compounds by understanding the role of cations and anions, as well as the presence of metals and nonmetals. It emphasizes the importance of prior knowledge about atoms, ions, elements, compounds, and the periodic table. The video provides examples like NaCl, MgF2, and Al2O3 to illustrate the concepts, highlighting the significance of the periodic table in determining the nature of elements involved in forming ionic compounds.

What is the primary difference between an atom and an ion?

• An atom has a charge, while an ion is neutral.

• An atom is neutral, while an ion has a charge.

• An atom is a compound, while an ion is an element.

• An atom is larger than an ion.

Which of the following best describes an ionic compound?

• A compound made of two identical elements.

• A compound made of a cation and an anion.

• A compound made of two nonmetals.

• A compound made of two metals.

What is the role of the periodic table in identifying ionic compounds?

• It lists all possible ionic compounds.

• It provides the atomic mass of elements.

• It shows which elements are metals and nonmetals.

• It helps identify the charge of ions.

Why is NaCl considered an ionic compound?

• It is made of two metals.

• It is made of two nonmetals.

• It is made of identical elements.

• It is made of a metal and a nonmetal.

Which of the following is true about MgF2?

• It is not an ionic compound.

• It is made of two nonmetals.

• It is made of two metals.

• It is made of a metal and a nonmetal.
