In this set of practice problems, we will go over the atomic structure, subatomic particles, determining the number of protons, neutrons, and electrons, as well as writing correct chemical formulas. Check Also Subatomic particles and Isotopes Naming Monatomic and … Read more
These practice problems on naming ionic compounds such as acids, bases, and salts are based on the material we covered in the previous post. You need to know the names o monatomic (monoatomic) and polyatomic ions as well as some … Read more
There are a few definitions of acids and bases which we covered in an earlier post. Although it is not always accurate, you can recognize acids when you see an H with any of the anions you learned so far. … Read more
Naming molecular compounds is similar to naming ionic compounds in that we treat the first element as if it is a cation, while the second element is an anion. This means the name of the first element is what it … Read more
In the previous post, we talked about naming monatomic (monoatomic) and polyatomic ions. Once you know the names of the common ions, it is not difficult to name ionic compounds as we only need to put the names of the … Read more
Naming Monoatomic Cations and Anions For naming purposes, ions can be divided into two types: monatomic (monoatomic) and polyatomic ions. Monatomic ions are formed when an element gains or loses an electron(s). Metals tend to lose electron(s) and become cations (positively charged … Read more
Percentage composition shows the amount of each element in a compound expressed as a mass percent. To calculate the percentage of an element, multiply its molar mass and the subscript which shows how many moles of it are present in … Read more

What is the Mole? The mole is just a number like a dozen, a hundred, or a million. By definition, a mole is the number of atoms in a 12-g sample of 12C isotope which happens to be 6.022 x … Read more
Atomic Mass Because atoms and molecules are extremely small and we cannot weigh and work with them directly, there are a few ways you will see expressing their masses. This may be confusing at first but doing some practice and … Read more
