Protons, Neutrons and Electrons

Young scholars discuss how small they must cut something before it is no longer fundamentally the same. An online activity challenges and engages pupils in learning about the periodic table. Two hands-on activities cover elements and...

Three separate worksheets are rolled into this resource. The first focuses on atomic structure. The second reviews the concept of molar mass. The third relates atomic structure to element light spectra. These are definitely aimed at high...

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 resource would...

Up and atom! After labeling the parts of an atom, young chemists answer 16 diagram-based questions that deal with protons, neutrons, electrons, and atomic number.

The difference between atomic mass and atomic number can be confusing for some young chemists. Help your class better understand the concepts by allowing them to sketch an atom on paper and then discuss their experience. Upon completion...

Perfect for reviewing atomic components, this worksheet simply consists of a large, easy-to-read chart of 11 elements. Chemistry learners fill in the missing element symbol, number of protons, neutrons, and electrons, the atomic mass and...

Atoms may make up everything, but what are they made of? The narrator asks patrons at a local park what atoms are in an interview-style video. He then creates an atomic model and adds a neutron to it, opening the discussion to isotopes.

Just because we can't see an atom doesn't mean we can't study it! The video examines the makeup of the atom. It explains the roles of the protons, neutrons, and electrons. 

Learners are able to discuss the difference between a proton, a neutron and an electron. They also can explain the difference between an ionic and a covalent bond. Students know the main structure of atoms and molecules. Student are able...

What does an atom look like? The instructor in a tutorial video models how to use the periodic table to determine the number of subatomic particles. He then uses the number of electrons to create an orbital diagram. Finally, Groves...
