![]() ![]() In this case, the molecule that has been created is NaCl, known as sodium chloride or, more commonly, table salt. They have formed a molecule, which is the name of a substance formed from the combination of atoms. This charged bond is known as an ionic bond.īy forming an ionic bond, the sodium and chlorine are not separate atoms anymore. When metals and non-metals chemically react, the atoms will tend to form. The charged sodium and chlorine atoms become attracted to each other and form a bond. As with magnets, positive and negative charges in atoms are attracted to each other. The chlorine atom now has more electrons, which have a negative charge, than protons, so it now has a negative charge. Metals tend to form cations (positive ions) by donating electrons. Because protons have a positive charge, the sodium atom now has a positive charge. American Association of Chemistry Teachers 1-302 1 Name: Activity: Ionic Bonding Puzzle Background Ionic compounds are made up of a metal and a non-metal, when the atoms react they form ions (charged atoms). However, the sodium atom now has more protons than electrons. So, the chlorine atom will take the sodium’s electron and both atoms are happy. The chlorine atom has an outer shell with 7 electrons and only needs one more to fill its shell. It can do this by taking electrons from the shells of other atoms or by giving away electrons until it loses its outermost shell and a full inner shell takes its place.įor example, the sodium atom has an outer shell with only 1 electron, which it wants to get rid of. Introduction - When metals and non-metals chemically react, the atoms will tend to form ions or charged. However, atoms want to have an outermost shell that is completely full of electrons. 6-2L Class Exercise - Ionic Bonding Puzzle Lab. Atoms are made of a nucleus (a core or center) that contains particles called protons and outer shells made of electrons.Īn atom always has an equal number of protons and electrons. Elements include substances like oxygen, nitrogen, and carbon. In this activity you will create models of ionic compounds and identify the chemical formula of the molecules you have created. Ionic bonds are also known as electrovalent bonds.Įverything in the universe is made of atoms, the smallest possible form of an element. of why atoms form ions, and how ionic compounds form by ionic bonding. Repeat steps 5-11 to finish the data sheet for all ionic bonds.An ionic bond is a chemical bond formed when one atom gives up one or more electrons to another atom. A fun logic puzzle which tests learners recollection of the relationship between. It is important that you cut them out precisely so that they fit together well. You may want to use card stock or some color of paper other than white but this is not necessary. In the last box, write out the chemical formula for the molecule using symbols and subscripts. Activities Using Ion Puzzle Pieces Print out the pieces (8 pages). (How many of each made a perfect rectangle?) 11. In the 4th box, calculate how many of each ion is needed to balance the molecule out to a zero charge. If they do not make a perfect rectangle, then add another piece with the same names until you get a perfect rectangle. Write out only the charge of each ion with a + or – sign in front of the number in the 3rd box. ![]() Teacher Preparation: 1 hour (the first time) Lesson: 50 minutes. Ionic Bonding Polyatomic ions Naming ionic compounds Electron dot structures Time. This activity supports students’ understanding of. ![]() Write the ion symbol and charge from each of the models in the second box. Use electron dot diagrams to show how ionic compounds form Name ionic compounds Chemistry Topics. In the first box, write the metal ion name from the model, then write the non-metal ion name under it. Pull one of each ion model for the elements listed. What happens when you put any +1 and -1 ion model together? It shows a balanced ionic molecule by creating a perfect rectangle. Think about why some have “outies” and some have “innies”. Notice the shape and charge of each ion model in each group. Lay all of them out on the table according to the group number they belong to on the periodic table. Youll receive 2 points for each correctly built molecule. Ionic Bonding Puzzle Lab In this activity you will create models of ionic compounds and identify the chemical formula of the molecules you have created. In this game, your challenge is to create a compound by combining individual ions. ![]()
