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

15 question worksheet with detailed instructions in which the student has to either write the formula or correctly name different covalent compounds. Excellent to teach the skill or as extra practice or homework. See it on TpT

Writing Neutral Formulas for Binary Ionic Compounds - Practice Problems 2 examples and 10 practice problems! Directions include common charges for elements in groups 1-7 as well as an explanation that transition metals are named in compounds with their roman numeral being equal to their ionic charge. This is excellent practice to get this skill taught fast! See it on TpT

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.

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

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!

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 includes 2 examples and 11 practice problems for balancing chemical equations. See it on TpT

Challenge your students with naming the 14 ionic compounds in this worksheet designed to help develop and reinforce the skill post-instruction. See it on TpT

Challenge your students’ understanding of the Law of Conservation of Mass with this great worksheet that has 2 elaborated examples and 8 original practice problems. It also includes an elaborated answer key. Enjoy! HS-PS1-7 See it on TpT

Bohr Model Paper Lab - Draw or Cut & Paste Particles + Neutral Atom Info This can be modified to fit your students’ needs. It’s a paper lab on creating Bohr models that are full-page along with looking up information on neutral atoms of whatever elements you assign the students to complete. 3 energy levels included should accommodate atomic numbers 1-20.

Chemical Bonds Lab: Growing Ionic Crystals! Solutions, Solubility, Saturation This is a lab designed for 7-9th grades where students pick either halite, epsomite, or alum to grow crystals with. The student handout is comprehensive and thorough. Every year I do this lab the kids have a blast. It is designed for the teacher to do the heating for super saturation. I personally use a large griddle of my own to heat several beakers at a time. I recently acquired access to several hot plates and ran this lab by allowing students to do their own heating. It works either way! See it on TpT

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.
