Read:
An Ion is a charged atom, # protons ≠ # electrons. On page three, paragraph one states, “The prefix poly- means many and atomic refers to atoms, so a polyatomic ion is an ion that contains more than one atom. This differentiates polyatomic ions from monatomic ions, which contain only one atom.” Ions that contain only one atom are called monoatomic ions. Ions that contain more than one atom are called polyatomic ions. A monatomic ion is a single charged atom, with the number of protons not equal to the number of electrons. A polyatomic ion is a group of covalently-bonded atoms, with the total number of protons not equal to the total number of electrons.

How could we use the image of the ionic compounds to elaborate on the question that is answered in the image attached? How does that image show polyatomic and monoatomic ions?
Fill in the blank with the correct response:
Recall the rules for naming cations, anions, and ionic compounds.Cations are named according to the following rules.
•
When a cation is made from a metal atom, it is given the same name as the metal. For example, K+ is called the potassium ion, and Mg2+ is called the magnesium ion.
•
Certain metals, particularly transition metals, can form multiple cations, each with a different charge. In that case, the name of the metal is followed by a (______________) letter or number or Roman numeral (enclosed in parentheses) that indicates the amount of charge. For example, tin can form the cations Sn2+ and Sn4+. Sn2+ is called the tin(II) ion and Sn4+ is called the tin(IV) ion. Mercury is unique in that it can form the cations Hg22+ and Hg2+. Hg22+ is called the mercury(I) ion and Hg2+ is called the mercury(II) ion.
•
Some polyatomic cations are formed from nonmetal atoms, and they are named with the suffix -ium.…

If you know that each copper atom (radius = 128 pm) has a mass of 1.055 1022 g (you will learn in Chapter 2 how to find the mass of one atom), how many atoms are there in this cube? What fraction of the cube is filled with atoms? (Or conversely, how much of the lattice is empty space?) Why is there empty space in the lattice?

You have learned something about the cations sodium (Na+), calcium (Ca2+), and potassium (K+) in this chapter. Use your knowledge of the definition of a cation to identify other examples from the periodic table.arrow_forwardIons that form from one atom on the Periodic Table are call monatomic ions. However not all ionic bonds are formed with monatomic ions, polyatomic ions can form ionic bonds as well. The prefix poly- means many and atomic refers to atoms, so a polyatomic ion is an ion that contains more than one atom. This differentiates polyatomic ions from monatomic ions, which contain only one atom. Examples of monatomic ions include Na+, Fe3+, Cl-, and many, many others. We can think about polyatomic ions by comparing them to monatomic ions. A monatomic ion is an atom that has been ionized by gaining or losing electrons. The ion has a net charge because the total number of electrons is not balanced by the total number of protons in the nucleus. Thus, compared to the neutral atom, we have extra electrons—in the case of a negatively charged anion—or not enough electrons—in the case of a positively charged cation. For example, a neutral chlorine atom has an atomic number of 17, which means it has 17…arrow_forward
