All the atoms and ions with ten electrons along with their symbols and charge are to be listed, and the chemical formulas of various compounds that can be formed by combining them are to be written. Concept Introduction: An atom is a pure and indivisible unit of an element that has no charge on it. The number of electrons and protons in a neutral gaseous atom is equal. If the number of electrons in an atom is more than the number of protons, then the atom is termed as an ion with a negative charge. If the number of electrons in an atom is less than the number of protons, then the ion is considered to be positively charged.

Concept Introduction:

An atom is a pure and indivisible unit of an element that has no charge on it. The number of electrons and protons in a neutral gaseous atom is equal. If the number of electrons in an atom is more than the number of protons, then the atom is termed as an ion with a negative charge. If the number of electrons in an atom is less than the number of protons, then the ion is considered to be positively charged.

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.

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.

Now that we have a reference for many of the common polyatomic ions, let's look at how to write the chemical formulas for compounds that contain them. There are two main things to keep in mind: If a compound contains more than one polyatomic ion of the same type, we need to place parentheses around the ion's formula beforeusing a subscript to indicate how many ions of that type are in the compound. The overall charge for the ionic compound must be neutral, which means the sum of the charges from the cations and anions should add up to zero.We can use this rule to figure out the formula of an ionic compound when we know the charge on the anion and the cation. This rule can also be useful for deducing the charge of an ion when the chemical formula for the ionic compound is known. Example: Write the chemical formula for calcium hydroxide (calcium and hydroxide). Calcium is an alkaline earth metal in Group 2 on the periodic table, so it forms ions with a 2+ charge.
