Order, Order All Electrons

Although the directions say to view a PowerPoint, it is not necessary in order to complete this assignment. Six fill in the blank questions survey the periodic table of elements. A chart follows in which, given the element symbol, young...

In this electron dot structures handout, new chemists read about electron arrangement and how to draw electron dot diagrams. They complete a chart with the mass number, atomic number, isotope notation, number of neutrons, and Bohr...

In this location of electrons worksheet, students read about the quantum mechanical model of the atom and the location of electrons. They complete a table given eleven elements with the sublevel notation, the Bohr notation and the...

In this electron worksheet, high schoolers read about how atoms lose and gain electrons and how they become ions. They are given a table with nine elements and they give the electron configuration, the number of electrons, the number of...

A periodic table of elements and ten accompanying questions comprise this chemistry handout. Learners survey the table to discover the relationship between group columns and valence electrons. They also associate energy levels to the...

Don't have an electron microscope? Have your classes build the next best thing! A hands-on lesson asks scholars to build a model of Transmission Electron Microscope (TEM). They then use their models to identify the function of each...

The National Chemistry Olympiad exams are comprehensive tests covering an entire  year of chemistry concepts. You can use them as practice for competing in the challenge, or simply as a review, or as an actual final exam for your general...

This compendious collection of slides leaves no questions when it comes to the concept of atomic size. Thorough and easy-to-read graphs, tables, and graphics explain atomic radii, the shielding effect, the octet rule, isoelectric...

Before determining which electrons are available for reactions, scientists identify each atom's electron configuration. An informative video from Socratica's chemistry playlist includes how to write electron configurations. It explains...

It's hard to keep track of electrons ... that's where electron configurations come to the rescue. A short video in the JFR Science series highlights electron configurations and how to write both condensed and expanded notation. It...
