GED® Science: Atoms, Elements & the Periodic Table (Deep Dive)
A deep dive into the building blocks of matter, expanding the single 'Atoms, Elements & the Periodic Table' lesson from the GED® Physical Science course into a full mini-course. You'll explore the structure of the atom, learn to read an element box and count protons, neutrons, and electrons, see how electrons fill shells, understand how the periodic table is organized, and tell elements from compounds and ions from isotopes. Plain language, all-new labeled diagrams, common-misconception warnings, and GED®-style practice with full explanations.
