30 paź 2017 · This document discusses ions and how they are formed. It explains that atoms become ions by gaining or losing electrons to obtain a full outer electron shell. Atoms that gain electrons become negatively charged ions and atoms that lose electrons become positively charged ions.
7 lip 2018 · It discusses the rules for naming binary ionic compounds that contain metals and nonmetals (types I and II), binary covalent compounds between two nonmetals (type III), compounds containing polyatomic ions, and acids. Examples of applying the naming conventions are provided throughout.
I. Metals that form more than one ion, such as iron, add a Roman numeral to the name to indicate the charge: Fe 2+ is called iron (II) and Fe 3+ is called iron (III)
Naming Ions. The name of a monatomic cation is simply the name of the element followed by the word ion. Thus, Na + is the sodium ion, Al 3+ is the aluminum ion, Ca 2+ is the calcium ion, and so forth. We have seen that some elements lose different numbers of electrons, producing ions of different charges (Figure 3.3 "Predicting Ionic Charges ...
Naming Polyatomic Ions • The name of the oxoanion ion changes when the number of oxygen atoms bonded to the central atom changes. Can you see any patterns? 20 Trends for Polyatomic Ions Figure 3.17 21 These are the ions listed on your in-class handout. You must memorize the ones in bold on the handout. 22 3.3 Formulas for Ionic Compounds

We have seen that some elements lose different numbers of electrons, producing ions of different charges.
Atoms of different elements differ by the number of protons in their nucleus. All atoms of an element have the same number of protons. The number of protons in an atom of an element is called its atomic number. The atomic number is indicated on most periodic tables above the element symbol.
