Atomic Structure and Notation Lesson - Google Slides and PowerPoint Lesson by Teach Simple

About this resource

What's inside this resource

A Google Slides and PowerPoint chemistry lesson walks students through atomic structure — protons, neutrons, and electrons and their charge, mass, and location — before covering atomic number, atomic mass, isotopes, calculating a weighted average atomic mass, and periodic-table notation with superscript mass number and subscript atomic number. The student slide deck presents the same content as fill-in-the-blank cloze notes, while a parallel teacher version of the slides and a matching PDF supply every blank filled in, including worked 'Check Your Understanding' problems such as finding an atom's protons, neutrons, and electrons from its atomic number and mass number. A companion 'Bill Nye: Atoms' worksheet asks 14 short questions tied to the referenced video, provided in both blank and fully answered versions. A separate printable Word outline offers the same cloze notes for students who prefer paper over slides. Once students can read atomic mass and isotope notation from the periodic table, mole conversion practice applies those same atomic mass values to stoichiometry calculations.

In the classroom

Teaching tips & learning objectives

Learning objectives

Identify the charge, relative mass, and location of protons, neutrons, and electrons in an atom
Determine an element's number of protons, neutrons, and electrons from its atomic number and mass number
Calculate the weighted average atomic mass of an element from its isotopes and their abundances
Read and interpret periodic-table notation, including atomic number, mass number, and chemical symbol

Teaching tips

Use the student cloze-deck for guided note-taking, then reveal the completed teacher deck to check answers as a class.
Assign the 'Check Your Understanding' problems as independent practice after modeling the worked isotope example.
Pair the 'Bill Nye: Atoms' worksheet with the referenced video for a video-response comprehension check separate from the slide content.
Remove the 'Special Bonus Resource' promotional page before distributing to students, since it links to the seller's external site rather than lesson content.

Skills covered

Atomic structure identification — students classify protons, neutrons, and electrons by charge, mass, and location within the atom.
Atomic mass calculation — students compute a weighted average atomic mass from isotope abundances, e.g. (4×0.5)+(5×0.4)+(6×0.1)=4.6.
Periodic notation interpretation — students read atomic number and mass number from standard element notation to find proton, neutron, and electron counts.
Video-based science comprehension — students answer content questions after watching a referenced video on atomic theory.

Good to know

Questions teachers ask about this resource

How does the lesson differentiate between the student and teacher versions of the slides?

The student deck leaves key terms and answers blank as cloze notes to fill in during the lesson, while the teacher deck and matching PDF present the identical slides with every blank completed.

What does the 'Bill Nye: Atoms' worksheet assume students have already done?

It assumes students have watched a specific referenced Bill Nye video on atoms, since questions such as describing the water-splitting experiment are only answerable after viewing that video.
