Multiple Select

Which of the following is an ionic compound?

How do we know if a compound is ionic or covalent?

Multiple Select

What are the properties of ionic compounds?

• low melting and boiling point

• high melting and boiling point

• can conduct electricity in aqueous solution

• poor electrical conductor in liquid form

Properties of Ionic Compounds

• high melting and boiling point

• can conduct electricity when they are dissolved in water

• hard, rigid, and brittle

• generally soluble in water

• form crystals

Multiple Choice

How do we determine if a compound is ionic or covalent?

• in binary ionic compounds, it is composed of a metal and a non-metal

• in binary ionic compound, it is composed of two non metals

• in binary ionic compounds, it is composed of two metals

Ionic compounds

are composed of a positive ion (cation) and a negative ion (anion)

Multiple Choice

Which of the following is an example of binary ionic compound?

• CaCl₂

• H₂O

• O₂

• Fe(OH)₃

Binary Ionic Compound

A binary ionic compound is a compound composed of a monatomic metal cation and a monatomic nonmetal anion. The metal cation is named first, followed by the nonmetal anion.

Multiple Choice

Which of the following is NOT an example of binary ionic compound?

• AlF₃

• Co₂O₃

• ZnBr₂

• NH₄Cl

Ternary Ionic Compound

 A ternary ionic compound is an ionic compound composed of three elements. In a typical ternary ionic compound, there is still one type of cation and one type of anion involved. The cation, the anion, or both, are polyatomic ions.

Multiple Choice

Which of the following is NOT an example of a polyatomic ion?

• NH₄⁺_

• Cr₂O₇^2-

• SO₄^2-

• CO₂

Multiple Choice

How do we name ionic compounds?

• We name first the cation before the anion

• We name anion first before the cation

Rules in naming ionic compounds

1. name first the cation before the anion

2. for those with 2 or more oxidation, we identify the oxidation in writing the name of the compound

example: Copper (II) oxide or Copper (I) oxide
