Predicting Ionic Charge - Basic A Group Elements to Ions HS-PS1-1 Practice problems predicting basic ionic charges of groups 1A , 2A, 3A, 5A, 6A, and 7A elements. This sheet requires the students to reason how many electrons are gained or lost and what the charge and ionic symbols should be. See it on TpT

Here is a nice worksheet I made for my 9th grade Physical Science classes that reviews the group and period number trends of the periodic table. If you have taught your students OR need to teach them that the group # = the number of valence electrons in those elements’ atoms, and that the period # = the total number of energy levels of the atoms, then this is the worksheet for you! I have left a space for you to do an example with them before turning them loose on their own. Includes a key! See it on TpT

A nice worksheet for homework or simply class practice that covers classification of matter and conservation of mass. It includes matching as well as engaging classification questions that require higher order thinking skills. See it on TpT

Periodic Table - Groups vs. Periods Practice / Review Sheet - Using the Trends HS-PS1-1 Here is an excellent resource I made for practicing or reviewing the group vs. period trends, including numbers of valence electrons and numbers of energy levels. It is a two page student handout (1 pg. front and back) and a complete teacher’s key. See it on TpT

24 practice problems in counting atoms in compounds. First page focuses on compounds with formulas that do not have parenthesis or coefficients. The second sheet/back has 12 problems with parentheses and coefficients (both stoichiometric and in hydrates). Great homework or for teaching these skills. Designed as drill practice to reinforce instruction. Scaffolded for advanced students by requiring them to list compounds’ constituant atoms before counting as well as requiring them to look up compound names. You can modify this part of the assignment as you wish. Enjoy! Please review and follow!

This is hands down the ultimate worksheet for writing and naming ionic and covalent formulas. I get great results with it each year, and it is very versatile. This could be used as a class activity when teaching these skills, extra practice or homework, or even a quiz for advanced classes. See file preview for a sample with answers. 24 questions total that challenge students to classify the compound as ionic or covalent first, then they either write out the compound name or its chemical formula.

Spanish ELL Support for Density Practice Problems. I speak fluent Spanish, so this was translated for real, NOT using Google translate. 14 problemas de practica usando la formula para densidad para todos los variables. Disponible en ingles/Available in English

Challenge your students with these 24 practice problems for mass to moles and moles to mass conversions for elements (front) and compounds (back). This is perfect for teaching these skills, as extra practice for in class or for homework, or even as a quiz. Answer key included!

Challenge your students with these 14 original density problems where they solve for all variables in the density formula and more!

A station learning lab that incorporates the use of hands-on observation, YouTube video integration, and more about groups: Station 1: Alkali Metals – Chemical Reactivity Station 2: Alkaline Earth Metals – Atomic Radius Station 3: Transition Metals – Physical Properties Station 4: Carbon Family - Density Lab Station 5: Halogens – Melting Point Station 6: Noble Gases – Emission Spectra Minimal materials needed.

Here are 24 practice questions that ask students to classify each one as a physical property, physical change, chemical property, or chemical change. Complete with answer key! Spanish Version Available Here See it on TpT

This worksheet was designed to help my students get comfortable interpreting the numbers of valence electrons and energy levels for atoms using the group and period trends. It starts out with identifying numbers of energy levels and valence electrons, then requires students to rank elements using those numbers. Then it has students use the trends to identify both characteristics for the same elements. This is a quick activity to do together as a class or also works as a great homework assignment once the material is taught in class. See it on TpT
