Explanation:

1. An ancient study or art which attempted to combine science and philosophy to solve worldly problems is alchemy

2. A homogeneous mixture of elements with metals to form metallic solids is an alloy

3. The simplest unit of an element that still retains the properties of that element compound is an atom.

4. Two or more elements joined together such that the elements have lost their individual identity element is called a compound

5. A primary substance that cannot be divided into separate substance is an element

6. The group of elements that are good conductors of electricity and heat is called a metal

7. The group of elements that are poor conductors of electricity and heat are called non metals.
