The focus on ion formation is what atoms do to become stable, so this lesson is the first to access the Cross Cutting Concept of Stability and Change. In particular, we are setting up the high school level that states students will understand " Much of science deals with constructing explanations of how things change and how they remain stable. I got this worksheet from a colleague, who found it online.

Unfortunately, I have not been able to find it myself to give proper credit for its creation. If you know the origin of this work, please let me know so I can provide them the proper credit.

This video shows how we begin the lesson on the differences between atoms and ions. This is done via the document camera after all students have a paper and have put their names on the paper. After modeling for the whole class, I give students time to work with a partner to become more comfortable with the process. Students may choose a partner from a different table and move to the lab space, or work with a partner at their current table.

I remind students of our Bohr-Rutherford models from a couple days ago as a way to help them make the neutral atom drawing faster. I point out the reminders on the top of the page regarding how cations and anions are formed. I encourage them to write down that cations are formed by neutral atoms with valence electrons, and anions are formed by elements with valence electrons.

While students are working, I circulate the room to provide reinforcement, and answer questions. Whenever possible, I refer students back to the hints at the top of the page, their Bohr-Rutherford diagrams, and their Valence Electron notes.

I am trying to foster some independence in my students and break their need to always ask me questions. When we are close to the end of partner time, I give a two minute warning before we return to our seats at the front tables and check in. When we stop the action, I ask all students to find Phosphorus on page 2. I ask students to walk us through the process, asking for different information from each table. Now I pause and ask " How does this Phosphorus atom obey the octet rule and fill its valence shell?

I then prompt " How do we know when elements will give up or gain electrons? When we make our ion diagram, I encourage students to use a different symbol for the gained electrons, either an "X" or a checkmark.An ion is an atom or group of atoms with a positive or negative charge.

Ions form when atoms lose or gain electrons to obtain a full outer shell:. Metal atoms lose electrons from their outer shell when they form ions:. For elements in groups 1, 2 and 3, the number of electrons lost is the same as the group number. The outer shells of non-metal atoms gain electrons when they form ions:.

For elements in groups 6 and 7, the charge on the ion is equal to 8 minus group number. Sulfur is in group 6 of the periodic table. What is the charge on its ions, and is the charge positive or negative? The charge is negative, since sulfur is a non-metal.

Iodine is in group 7. The charge is negative, since iodine is a non-metal. Forming ions An ion is an atom or group of atoms with a positive or negative charge. Ions form when atoms lose or gain electrons to obtain a full outer shell: metal atoms lose electrons to form positively charged ions non-metal atoms gain electrons to form negatively charged ions Forming positive ions Metal atoms lose electrons from their outer shell when they form ions: the ions are positive, because they have more protons than electrons the ions formed have full outer shells the ions have the electronic structure of a noble gas group 0 elementwith a full outer shell For elements in groups 1, 2 and 3, the number of electrons lost is the same as the group number.

A sodium atom loses one electron to form a sodium ion Forming negative ions The outer shells of non-metal atoms gain electrons when they form ions: the ions formed are negative, because they have more electrons than protons the ions have the electronic structure of a noble gas group 0 elementwith a full outer shell For elements in groups 6 and 7, the charge on the ion is equal to 8 minus group number. An oxygen atom gains two electrons to form an oxide ion curriculum-key-fact.
