Good point, I recall learning how to use litmus paper back in high school. I am currently taking a few organic chemistry courses and I have to refer to the periodic table so often, I put an app on the tablet. It's really amazing all the useful information contained in the table. Organic chem puts more emphasis on how molecules interact and the primary elements are hydrogen, oxygen, sulfur, phosphorus and carbon. I need to refer to the periodic table so I know the atoms valance. I am also wondering if the upcoming chemists, pharmacist and doctors are knowledgeable on how basic chemistry works or do they just follow some manual.
I appreciate your support, thank you. Upvoted
Another important property of atoms in organic molecules is the concept of electronegativity. If you understand that electrons are strongly attracted by certain elements (e.g., N, O, Cl, etc.) and easily lost by other elements (e.g., H, Na, Si, Zn, Mg, Ca, etc.), then it helps to predict the properties of a structure and predict how it will react.
Thanks for the link.
How can one forget about electronegativity. Yes I have heard the term many times during my studies. Fluorine being the most electronegative. Another concept is resonance, I understand what it is but I am still learning. I get that it lowers the overall energy level. I had a quiz recently to draw up all the resonance forms of a molecule, I think there were 6 and I could only find 3. I still have some learning to do.
I have an app called "The Elements by Theodore Gray" that really brings the Periodic Table to life...very cool!
