Sal does a phenomenal job introducing students to the atom, and the history that goes along with how we understand and view atoms today. Students are introduced to the atomic number, and how elements are organized into the periodic table...

Nothing says organization quite like a table. The third lesson in a six-part Mixtures and Solutions unit teaches young scientists about elements and the periodic table. They learn how the periodic table is organized and about the...

In this countdown challenge worksheet, 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.

For this chemistry worksheet, students identify and name the number of neutrons, electrons, and protons for each. Then they illustrate how the electrons are arranged in a cloud. Students also find the relative number of atoms in the two...

In this atomic structure instructional activity, students answer eleven short answer questions about the structure of atoms including the number of protons, neutrons and electrons. Students indicate the differences in isotopes of atoms...

In this elementary particle mass activity, learners calculate the mass of elementary particles in kilograms and million electron Volts. Students solve 4 problems finding Top Quark mass, total quark mass of a proton and Strange Quark mass.

In the atom worksheet, students read a story about the "Atoms Family" and are given descriptions of the structures of atoms through the story. Students interpret the descriptions by drawing the described atom structure, they name of the...

In this Bohr model diagram worksheet, students draw the Bohr diagram for 6 elements. They show the number of electrons in each energy level and the total number of protons and neutrons in the nucleus.

In this masses of atoms worksheet, students complete a chart of 7 isotopes with their isotope symbol, atomic mass, atomic number, and the number of protons, neutrons and electrons. They calculate the average atomic mass of two elements.

In this chemistry instructional activity, 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...

In this atom worksheet, students read about the structure of the atom including its subatomic particles and John Dalton's theory of the atom. Students also read about the differences between atoms, molecules and compounds. They answer 30...

In this average atomic mass instructional activity, students read about how the protons and neutrons make up the atomic mass of an element. They find the average atomic mass given four problems.
