Do you also struggle with chemical formulas in chemistry? Then, examine the categorization of elements on the periodic table to get a better understanding of chemical formulas. Also, improve your understanding on the origins of standardized element categorization, as well as how it covers newly discovered elements and those yet to be discovered. Furthermore, learn about various periodic trends related to elements based on their physical properties. You will analyze different aspects of electrons of atoms covering valency, configurations, and dot formulas. Do you also want to learn about interesting ways of predicting the charges, electron configurations, and physical properties of elements based on their respective groups or periods? Then, enrol into the High School Chemistry: Atoms, Molecules, and Ions course right now to discuss specific methods for each prediction based on the periodic table.
Are you a student who wishes to avoid the problems when balancing chemical equations many chemistry students deal with? Or a teacher who wants to have your students grasp the basics of chemical formulas? To successfully pass this second certificate in a series of Regents exams in Chemistry there are fundamental requirements in formula writing that must be passed. This covers aspects of ions, atoms, and compounds all related by the periodic table. This course will carefully teach you the basics of each aspect using simple details for your understanding. Your understanding of these basics will be very useful in helping you recall the correct classifications of both monatomic and polyatomic ions based on their distinct properties. This will also aid your ability to name chemical formulas for common monatomic ions, polyatomic ions, binary ionic compounds, and molecular compounds. In addition, you will improve your ability in writing ions and compounds with ease as correctly expected by chemists in the field.

It is common in science to predict and use many hypotheses to better understand observations and situations through evidence. The evidence that is specially used in formulas, atoms, and ions in chemistry are the chemical reaction equations you have learnt. As for moles in chemistry, they are the evidence used in stoichiometry covering empirical formulas, molecular formulas, and even mass-volume calculations. These concepts are all combined to aid simple predictions on ionic compounds that are soluble in water together with conventional solubility rules set in the world of chemistry. It is also very typical in science to understand all types of changes including the microscopic ones chemistry tends to observe more. This course outlines general observations of both physical and chemical changes together with their properties. Start this course today to learn all about formula writing and the periodic table especially useful to your Regent exam in chemistry!
