In this ions worksheet, students answer a variety of questions about anions and cations as well as the octet rule and valence electrons. Types of questions include fill in the blanks, true and false and matching. They solve 3 problems including drawing Lewis structures, writing the number of electrons lost or gained in ions and describing metal and nonmetal ions.
Students perform flame tests on salts and record the electron configurations for various cations. They analyze and record the results using spectroscopes.
In this anions and cations learning exercise, students combine eight anions with eleven cations to form molecules. Students name the ions, the chemical name and the formula for each.
Students conduct an experiment in which they systematically separate cations from a mixture of substances. They use the following types of reactions to do so: precipitation, acids and bases, oxidation and reduction. They compare a standard solution to a waste-water solution to determine which cations are present.
In this naming compounds activity, students read through guidelines on naming different types of chemical ions and compounds then practice naming on their own. The naming compounds handout includes 100 practice problems in which they name ions, combine pairs of ions to make new formulas, write the ions and chemical formulas for compound names, name molecular compounds, name acids, and finish with naming additional chemical compounds by applying all they have studied in the packet.
In this solubility worksheet, students answer post activity questions about the lab work they completed with ionic compounds. They write sentences about solubility of cations from their lab work. They write chemical reactions for their experiments and they write net ionic equations.
In this compounds activity, students write the chemical formulas for ionic compounds given cations and anions. They are also given cations and anions and identify the number of cations and anions needed to write the appropriate chemical formula.
Here is an all-encompassing lesson on naming chemical compounds and writing formulas. It begins by using a color-coded periodic table to teach about the element groups: metals, transition metals, non-metals, and metalloids. Anions and cations are explained. Ionic and molecular compounds are compared. Finally, the viewers are taught how to name and write chemical formulas for them. This comprehensive PowerPoint even provides opportunities for practicing names and formulas.
Chemistry students review the trends found in the organization of the periodic table by completing this worksheet. They determine which of the given atoms has the largest ionic radius and which is the most electronegative. This worksheet has 6 matching, 4 true or false, 10 fill in the blank, and 2 problems to solve. It is neatly formatted and pertinent to any general chemistry curriculum.
In this ionic compounds worksheet, students complete two tables with the chemical formulas given the cations and anions that bond.
More of an instructional handout than a practical worksheet, this resource explains how to predict the pH of salt solutions. It notes that most cations are acidic, whereas most anions are basic. To determine the pH of a solution, this information is necessary and is used to determine whether or not excess hydrogen or hydroxy ions result in a reaction. This is a useful reference sheet for your chemistry learners, or if you display it on a screen, a supportive outline to your lecture.
There are three cation solutions to be tested in this lab guide. Young scientists will get practice using a wire loop and using it to perform a flame test.
In this ions worksheet, students answer 5 questions and then fill in a chart with 16 elements. They identify the element's charge and symbol, if it's a metal or non-metal and if it's an anion or cation.
The heading that tops this assignment is humourous, but specifically directed at a group of chemistry kids who apparently did not perform very well on an exam. The questions that follow are meant to review concepts that they need additional practice with. You could use the questions as a review for your own class, but you might want to replace the blurb at the top with something more personal. The topics covered by the multiple choice questions include binary molecular compounds, oxidation states, anions and cations, and writing molecular formulas.
Binary compounds are explained with the periodic table, atomic charges, and examples. Viewers are taught to name binary compounds and then are presented with a chart of cations and ions. Finally, they see a few photos of forms of silicon dioxide. There is also a slide with invalid links. It seems that the slides would make more sense to be shown from the end to the beginning. Rearrange them for the best presentation.
In this ionic compounds worksheet, students fill in 8 blanks with the appropriate terms, they determine if 4 statements are true or false, they match 4 terms with their definition and they name and write the formulas of compounds. Students use polyatomic ions for compounds and write formulas for binary compounds.
Students explore how to show evidence of subshells and electron filling on the visual scale. They examine subshell filling and evaluate unknowns based on the atomic emission spectrum. Students design an experiment to identify colors of metal cations.
In this compounds worksheet, students review how to name inorganic compounds and then complete 2 graphic organizers naming the cations and anions.
In this compounds worksheet, students explain how a neutral atom becomes a cation and why ionic compounds have high melting and boiling points. This worksheet has 6 short answer questions.
