The purpose of this experiment was to explore the properties of chemical substances that can be used to identify the types of bonds in a chemical substance using a laboratory procedure. The two types of bonds being identified were ionic and covalent. Based on a substance’s properties, how can you determine whether its bonds are ionic or covalent? This is the question I posed before starting the experiment.

Each chemical compounds has a certain percentage of ionic character in its bonds and the remaining percentage as covalent bonds. The only compounds that are accepted as being 100 percent covalent are the chemical combinations that happen between two similar atoms.However if atoms are different in the compound it will present a certain percentage of ionicity in its

Concept 2.1 Matter consists of chemical elements in pure form and in combinations called compounds

I think the course is very informative and practical. I enjoy your input given trough our weekly meetings and the ideas and opinions that are posted from other teachers in the discussion section. My only concern is the amount of reading assignments that we need to have done every week. It might be that I need to organize my self better. Overall I am enjoying the class. Thank you for the kindness and flexibility that you offer us in case of emergencies or difficult situations.

In chemistry, chemists determine which bond belongs to which molecule have. Electronegativity values are used as well to help determine which bond belongs to which molecule. The bonds scientists use are: covalent bonds, which is when the electrons are shared equally, Polar covalent bonds this is when the electrons are shared unequally, and ionic bonds which are when electrons are transferred from one atom to the other. The difference between the ionic and covalent bonds are: ionic bonds have electrons that are shared between atoms, while covalent bonds have electrons that are shared equally or unequally inside one molecule. Ionic Bonds are formed when a complete transfer of valence electrons between atoms happens. An example of an ionic bond

The two types of bonds that hold atoms within a compound together are ionic and covalent bonds.

There're two types molecular molecules, diatomic or polyatomic. Most commonly molecular elements exist as diatomic molecules meaning they consist of two atoms. An example of Diatomic molecules would be hydrogen H2 or Oxegen O2. Secondly, polyatomic molecules consist of many atoms, more than two. An example of a polyatomic molecule would be sulfur which exist as S8. Polyatomic molecules are not common.

Molecules are categorised by two groups, molecules not consisting of carbon atoms are known as inorganic, and these inorganic molecules generally either dissolve in water or react with water in order to release ions which are commonly known as electrolytes. However, molecules containing both carbon and hydrogen atoms are known as organic but the organic

Also, many organic compounds are carbon compounds, and organic compounds exist as mostly mixtures, and there are various techniques to “purity”. Organic compounds are characterized by a variety of chemical tests that are called “wet methods”. Examples of some organic molecules

I think that this course was scheduled very well and taking a course in under two weeks has definitely been a struggle at times trying to retain so much information yet staying focused on one course at a time is nice. As far as improvements to make this course better, I can not think of anything that I would change to make it better. This is my fourth online course to take through Blinn Community College and I would say that this is the best paced course and most interesting course I have taken so far.

My overall experience in this course was wonderful, as I enjoyed doing and administering the assessment tools provided to us. The new assessment materials have impacted me each week’s lecture tremendously. The in-class exercises were practical and assessment tools were spot on although some of the manuals were not useful. The reading material were spot on, as it was coordinated with each week’s lectures. The weekly reading assignments and reflection papers were helpful.

Atoms are the basis of everything we know of, but molecules are what atoms tend to
