Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...

In this atomic weight and ions worksheet, students answer questions about isotopes of atoms and how it relates to atomic weight. They also write out oxidation or reduction reactions for given atoms undergoing loss or gain of electrons.

Although the focus of this worksheet is the neutron, you cannot talke about them without also dealing with protons and electrons! Chemistry kids fill in a table of 14 elements, identifying the mass, atomic number, isotopic symbol, and...

In this atom worksheet, chemists learn how to determine the number of protons, neutrons and electrons in an atom using the atomic mass and atomic number. They complete a chart of the subatomic particles and use marbles to represent...

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...

Atomic theory, experiments that contributed to our knowledge of matter, atomic structure, isotopes, and ions are covered in these 33 slides. Quality diagrams and labeled charts will help activate understanding. The presentation concludes...

In this formulas and equations worksheet, chemistry apprentices write the chemical formulas given the names. They calculate percent composition, balance equations, and calculate the mass of a substance present in a fertilizer. This is a...

This PowerPoint is a comprehensive review of all the facts related to an atom's basic structure and function. What makes this unique is that it is geared toward an audience of junior geologists. After introducing the periodic table of...

In chemistry, the mole is a unit of measurement, much like a millimeter or liter. After learning about moles, scholars learn various equations relating to mass, volume, and concentration. They review each of these equations in a few...

In this elements worksheet, students review the information that is found on a periodic table including atomic mass, chemical symbol, atomic, number, and electron configuration. This worksheet has 7 fill in the blank questions.

Referring to the periodic table of elements, nuclear physics learners determine the resulting elements of alpha and beta decay. Answers are given in atomic notation, showing the atomic symbol, mass, atomic number, and emission particles....

It's electronic! Pupils uncover elements and their electron configurations as they explore mass, groupings, correct charges, and sliding theory. Young scientists learn creative ways to remember various elements and correctly...

For this chemistry worksheet, students use the periodic table of elements in order to identify the common elements. The detail is very detailed.

Is your class in a quandary over quantum numbers? Change things up by adding games to the mix! Science scholars discover the shape, number of electrons, and number of orbitals in the s, p, and d sub-shells using an interactive.

Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.

Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.

This activity allows young scholars to gain an understanding of the relationship between the mass and relative abundance of an isotope and its effect on the average atomic mass of the element. Students will be given a random sample of...

You will be presented with three different isotopes of the same element. See if you can calculate the atom's average relative mass.
