Topic 6

Question 1

Molecular Compound

Answer 1

Usually formed by 2 non metallic elements.

They share electrons

Question 2

Ionic Compound

Answer 2

Formed from metallic and non-metallic elements.

One element gives electrons and the other takes. This forms ion(positively or negatively charged atoms.)

Question 3

Diatomic Molecule

Answer 3

Molecules that are made up of 2 atoms of the same element

Question 4

Naming Molecular Compounds

Answer 4

1. Write the entire name of the first element
2. Change the ending on the name of the second element to -ide
   3.Use a prefix to indicate the number of each type of element in the formula.
   ONLY MONO for the second element

Question 5

Naming Ionic Compounds

Answer 5

1. The name includes both elements in the compound, with the name of the metallic element first
2. The non metallic element is second. Its ending is changed to -ide
3. Subscripts indicate the ratio of ions in the compound.

Question 6

Common characteristics of Molecular Compounds

Answer 6

• They do not form ions in a solution
• Usually do not conduct electricity
• Solid, Liquid, or gas at room temp
• Have low boiling points and melting points and the attraction between the molecules are weak

Question 7

Common characteristics of Ionic Compounds

Answer 7

• They are very strong and have a high melting point because if strong ionic bonds
• They are solid at room temp
• Form ions in solution
• They are good conductors when they are in a solution
