periodic table, a tool used by chemists to organize elements based on their properties. Elements are arranged in rows (periods) and columns (groups or families) according to their atomic number, which is the number of protons in thenucleus of an atom. Elements in the same group often share similar chemical properties because they have the samenumber of valence electrons. For example, the alkali metals in Group 1 are all highly reactive with water. Which of thefollowing best describes the organization of the periodic table?A) Elements are arranged alphabetically based on their names.B) Elements are arranged in order of increasing atomic number, with similar properties recurring in groups.C) Elements are arranged by their density, with heavier elements placed at the top.D) Elements are arranged based on the date of their discovery.

Ions 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…

In an alien world, a different periodic table exists. It is organized similar to the periodic table in our world, just smaller. The first group contains the alkali metals, the second group the alkaline earth metals, there are a few transition metals, and then some non-metals. The periodic table is shown below in picture form, and a table is given with molar masses and common ionic charges. Also in the table is a list of common ion groups (similar to carbonate, nitrate, etc. in our world.)

There was a part missing from the first one. This activity is structured as a game, wherein your challenge is to create correct ionic compound formulas by combining individual ions based on their charges. Once you correctly connect the atoms in the interactive website, a common use for that compound will be revealed. In the chart, record both the correct formula for each of seven ionic compounds and their common uses as revealed by the interactive program.
