Ionic compound

The video tutorial explains the nature of non-metal elements and uses sodium chloride as a classic example of ionic bonding. It describes how ionic compounds form large, ordered crystalline solids with ions arranged in a lattice. These compounds are characterized by being hard, brittle, and having high melting and boiling points.

What is a classic example of a compound formed by combining non-metal elements?

• Sodium chloride

• Water

• Carbon dioxide

• Methane

How do ionic compounds differ from covalently bonded compounds in terms of structure?

• They have no definite shape

• They are always gaseous

• They form large ordered crystalline solids

• They form discrete molecules

What is the arrangement of ions in ionic compounds?

• Randomly scattered

• In a gaseous form

• In a lattice

• In a liquid form

Which of the following is a characteristic of ionic compounds?

• Hard and brittle

• Low melting points

• Soft and flexible

• Easily vaporized

What can be said about the melting and boiling points of ionic compounds?

• They have low melting and boiling points

• They have high melting and boiling points

• They do not melt or boil

• They have variable melting and boiling points
