Atoms and Molecules Worksheets

The basic building block of all matter, atoms are at the core of all that we see, touch, smell, feel, and taste. Molecules are formed when two or more atoms link up. A reasonable knowledge of atoms and molecules is indispensable for us to demystify the universe. Both substantially informative and excitingly illustratory, our atoms and molecules worksheets for grade 5 through grade 8 take students through all relevant aspects of the topic with such delicate attention for detail that by the end of the worksheets, learners leave thoroughly educated.

Atoms and Molecules | Chart

Atoms and Molecules | Chart

With concise-yet-telling definitions and easy-to-grasp examples, this printable atoms and molecules chart for grade 5 and grade 6 is a perfect prelude to the topic. The illustrations help ease into the concept.

Atoms vs Molecules

Atoms vs Molecules

How are atoms different from molecules? Seeking to take the hassle out of the topic, this pdf chart tells between the two in terms of their definitions, components, stabilities, separations, and more.

Elements vs. Compounds | Chart

Elements vs. Compounds | Chart

Elements and compounds are different from each other in many ways. For one, an element is a simple substance, but a compound is a chemical substance. And there's more to it! This printable chart has it all.

Identify Elements, Compounds & Mixtures

Identify Elements, Compounds & Mixtures

Is water an element, or is it a compound? Don't freak out! Identify substances as elements, compounds, and heterogeneous or homogeneous mixtures with this worksheet for 5th grade and 6th grade.

Elements or Compounds? | Cut & Glue

Elements or Compounds? | Cut & Glue

This elements vs. compounds cut and glue activity enables students to brilliantly consolidate their knowledge. They cut out the molecular structures to sort and glue them under molecules or compounds.

Atomic Structure | Chart

Atomic Structure | Chart

It's high time we dug deep into an atom. In this printable, students broaden their horizons to know the structure of an atom that includes the nucleus, protons, neutrons, electrons, and electron shells.

Labeling the Atomic Structure

Labeling the Atomic Structure

Continue to excite grade 6 and grade 7 students with the task in this printable worksheet to label various parts of an atom, including the nucleus, a proton, a neutron, an electron.

Matching Molecular & Structural Formulas

Matching Molecular & Structural Formulas

With two distinct formulas for each compound in action, the interest in this worksheet becomes twofold. 7th grade and 8th grade learners are expected to match the structural formula to the molecular formula.

Calculating Atomicity

Calculating Atomicity

Atomicity is the number of atoms in the molecules of an element. In this 2-part atomicity worksheet, students interpret the atomicity of compounds first from their structures and then from their formulas.

Periodic Table

Periodic Table

The periodic table is an organized display of all the chemical elements. Go through these printable worksheets and activities that help comprehend the families, and groups of elements in the periodic table.

Electronic Configuration | Chart

Electronic Configuration | Chart

Electron configurations are the summary of where the electrons are around a nucleus. A perfect practice resource, this chart defines electronic configuration and illustrates it using the Aufbau Principle.

Identifying Electronic Configuration

Identifying Electronic Configuration

"SPDF" refers to the four different types of orbitals. In this grade 6 and grade 7 worksheet, children prove their mettle by correctly writing the electron configurations of elements using the SPDF notation.

Identifying Elements Based on Electronic Configuration

Identifying Elements Based on Electronic Configuration

Watch the SPDF notation at play yet again! In this pdf worksheet, though, the task for students is a little different. Let the young scientists identify the elements denoted by the given electronic configurations.

Hund's Rule | Orbital Filling Diagram

Hund's Rule | Orbital Filling Diagram

Hund's Rule clearly defines the behavior of unpaired valence shell electrons. In this printable exercise with six elements, high school students are tasked with drawing the Hund's Rule orbital diagram for each element.

Calculating Valency Electrons

Calculating Valency Electrons

Both transferable and shareable, valence electrons are the electrons in the outermost shell of an atom. In this pdf, middle school students write the electron configuration and write the valence electrons of each element.

Bohr Model Diagram

Bohr Model Diagram

Proposed by the Danish physicist Niels Bohr, the Bohr model is a household name in Chemistry. Children in grade 6, grade 7, and grade 8 draw a Bohr model for each element and identify the element represented by each Bohr Model.

Lewis Dot Structure

Lewis Dot Structure

A Lewis structure is one where element symbols represent atoms, and dots represent their electrons. In this worksheet, students draw the Lewis dot structure for each element, molecule, and compound.

Answer the Following

Answer the Following

The questions in this printable exercise include defining the laws of conversation of mass and constant proportions, explaining the two types of ions, and telling between isotopes and isobars.
