Chemistry formula writing activity
The goal is not to be equipped to write names and formulas for ionic compounds, but to recognize trends in naming. Add one of the suggested remedies and note the colour change.
In chemistry it is helpful to be able to heat chemicals. Keep going until it goes back to the original colour. Make sure you ask lots of questions to keep them interested in the demonstration.
Chemical formula worksheet
A list of suggested unknown solids and solutions is provided in this resource, which will help students better understand how polarity, intermolecular forces, and solubility are related. Above 0. After building the binary molecules, students determine the type of bond that is present by watching the sharing or exchange of electrons between to two atoms. A molecule is a group of atoms that are chemically joined together. Mix them together and ask your students to suggest how they might be separated. Make sure you ask lots of questions to keep them interested in the demonstration. Examples of ionic, covalent, and polar covalent bonds are animated, and students are given a set of compounds to predict the bonding types. The element cards can be downloaded, printed, and laminated for pairs of students to participate in this hands on activity. When you heat them together, they glow bright red exothermic and a new substance iron sulfide is formed, which cannot easily be separated. Submit your lab in the proper lab writeup format outlined in Module 1. What happens to the metals?
Keep going until each group has visited every station. Start by writing the metal ion with its charge, followed by the nonmetal ion with its charge. Students use ion cards with height that is related to charge to build ionic compounds with balanced charges in the Constructing Ionic Compounds activity.
Do not be tempted to treat an acid burn with alkali or vice versa — you might make the situation worse.
