Answer 2

Answer: The correct answer is metal and non-metal.

Explanation:

Elements are mainly divided into 3 classes in the periodic table.

1.) Metals: The element which lie on the left side of the periodic table are mainly metals. These elements loose electron easily and form positively charged species. These elements are present in the highest proportion in the periodic table.

2.) Non-metals: The elements which lie on the right side of the periodic table are considered as non-metals. These elements gain electrons easily and form negatively charged species.

3.) Metalloids: These lie between metals and non-metals and show the properties of both metals and non-metals.

Copper lie in the period 4 and group 11 of the periodic table and it can easily loose electron and hence, it is considered as a metal.

Chlorine lie in the period 3 and group 17 of the periodic table and it can easily gain electron and hence, considered as a non-metal.

Therefore, the correct answer is metal and non-metal.
