For this worksheet about molar mass, students find the molar mass or formula for 10 chemical compounds. This worksheet is printable and the answers are not available.

This science presentation focuses on the elements in the periodic table. It begins with the parts of an atom, explaining atomic mass and atomic number, valence electrons, and isotopes. Then it moves on to discuss various ways of...

For this chemistry worksheet, students determine which compound is the most acidic in each multiple choice question. Then they determine what the major product would be in each of the reactions stated on the sheet.

Words, words, words! This presentation uses plenty of them to define the atom, outline the history of what we know about atoms, and explain atomic and mass numbers. That's all! Informative, but not interesting, this slide show would be...

Guide your chemistry class through the periodic table so that they are able to identify atomic radii, electronegativity, and ionization energy. Give them three metals to place in water to observe reactivity. Teach them to write electron...

Neat! Show your physics class exactly how Ernest Rutherford fired alpha particles at a piece of gold foil and so determined that most of an atom is composed of empty space. Not just a slide show, but almost an animation, this...

In this isotopes worksheet, students review mass number, molecular notation, electron attraction, and electron orbits. This worksheet has 5 matching and 5 short answer questions.

In this elements worksheet, learners determine the atomic number, mass, number, electrons, protons, and neutrons for elements. Students review the electromagnetic spectrum. This worksheet has 1 graphic organizer and 13 multiple choice...

In this isotopes review sheet, students determine the atomic mass for three elements and they answer questions about isotopes.

For this chemistry worksheet, students use the clues given at the bottom of the sheet to solve the crossword puzzle on the Periodic Table. They describe the number of protons and electrons some elements posses, as well as identify their...

In this periodic table worksheet, students fill in missing information such as atomic number, atomic mass, family name, etc. using the periodic table as their reference.

In this problem solving worksheet, students are given five problems including calculating volume given the dimensions of a pool, determining the number of subatomic particles in an atom, filling in a table with chemical names and...

In this chemistry learning exercise, students read about atoms, their charges, and their parts; protons and neutrons. They examine how to determine atomic weight by looking at an example. They work online as they practice finding the...

In this thermochemistry worksheet, students indicate whether the given processes are endothermic or exothermic reactions. Students complete the phase change diagram as well as define a given set of vocabulary words. Students calculate...

In this early atomic theory worksheet, students answer 4 questions about the Law of Definite Proportions, the Law of Conservation of Mass and Dalton's Laws. Students are given 5 statements to determine if each true statement supports or...

In this countdown challenge learning exercise, students find the 10 common elements from the human body, earth's crust, and ancient times and color code them. Students fill the atomic number of the elements in a given periodic table.

In this atomic particles worksheet, students complete an elements chart comparing atomic number, mass number, protons, neutrons, and electrons. Students write the electron configuration for atoms. This worksheet has 1 graphic organizer...

Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this...

Young scholars investigate relative mass using 8 different items. In this relative masses lesson plan, students discuss as a class John Dalton's atomic theory. They take the masses of the 8 items and record their data. They discuss...

In this atomic structure instructional activity, students draw a helium atom and show the subatomic particles. They also answer questions about the Bohr model, Dalton's atomic theory and the energy of electrons based on their location in...

In this chemistry worksheet, students examine the periodic table and how it is used in the context of interpreting compounds and their structure.

In this atoms worksheet, high schoolers review atoms, atomic number, and mass number. Students determine what happens when atoms become radioactive. This worksheet has 8 fill in the blank and 9 short answer questions.
