Solution
For Question 1, the best descriptions of the Periodic Table are:
- Provides information about the elements such as, names, symbols and atomic numbers
- Arrangement of elements according to increasing atomic number
- Classification of elements in terms of chemical and physical properties
- List of all the elements we know on Earth
The Periodic Table does not arrange elements according to increasing mass number or abundance on Earth. It also does not classify molecules, but elements.
For Question 2, the descriptions match with elements on the Periodic Table as follows:
- Metals: These are elements that are good conductors of heat and electricity, malleable, and ductile. They are located on the left side of the Periodic Table.
- Non-metals: These are elements that are poor conductors of heat and electricity. They are located on the right side of the Periodic Table.
- Semi-metals (also known as Metalloids): These are elements that have properties of both metals and non-metals. They are located on the staircase line that distinguishes metals from non-metals on the Periodic Table.
