Chemistry

Why is it important to know characteristics that matter undergoes in chemistry? How can we analyze the relationships between chemical and physical changes and properties? Extension Questions: What is the study of Chemistry? Who are some of the important people who have contributed to the field? How do regular Americans interact with Chemistry around them?
How can we understand the historical development of the Periodic Table and apply its predictive power?
Extension Questions: Describe different chemical principles and systems. How does the layout of the periodic table allow you predict other element's properties? Consider all types and groups of elements.

Why is it important to know and understand the historical development of atomic theory?
Extension Questions: How does the atom relate to the elements of the periodic table? What are your most common models and how do they relate to the current atomic model? What theories don’t hold true today if any?
How do atoms combine to form ionic, covalent, and metallic bonds?
How can we write and balance chemical equations using the law of conservation of mass?

The retention factor of an ion is 0.10 .

Explanation:

Retention factor is defined as ratio of distance of distance traveled by solute to the distance traveled by solvent on chromatogram.

We have:
