Just added a new feature to most of the quizzes - pop-up periodic table! If your students happen to misplace their periodic table or you've activated tab-switch detection on an assignment, they can now use this instead. The pop-up calculator works alongside it, too! #chemed #iteachchem
A screenshot from ChemQuiz.net shows the new pop-up periodic table feature, which displays all of the elements with their element numbers, symbols and masses as well as different colors for each category (metals, metalloids, nonmetals and unknowns) A screenshot from ChemQuiz.net shows the new pop-up periodic table feature when the mouse is hovering over the square for element 26, which has expanded and is showing the element name "iron" instead of its element symbol A screenshot from ChemQuiz.net shows the new pop-up periodic table feature alongside the existing pop-up calculator feature

Tivy High School is a ChemQuiz.net school that's located in Kerrville TX, which was devastated by flooding this past July. Please consider helping their public school by donating to the Kerrville Public School Foundation, which gives out teaching grants and student scholarships! #chemsky #iteachchem

The August ChemQuiz.net newsletter is out! It includes information about the new PES and Coulomb's Law quizzes, as well as other new features across the site such as requiring students to round their answers using correct sig figs. Check it out! #chemsky #iteachchem mailchi.mp/chemquiz.net...
A screenshot of the PES Quiz at ChemQuiz.net shows a photoelectron spectroscopy graph below the question, "Which electron subshell is identified by the arrow in the following PES spectrum?" A screenshot of the Coulomb's Law Quiz at ChemQuiz.net shows a diagram of an atom below the question, "The atomic radius of polonium (Z = 84) is 1.35 × 10^-10 m. What is the magnitude of the electric force on its outermost electron?" A screenshot of the pop-up calculator that is now available on most of the quizzes on ChemQuiz.net

Just added the Coulomb's Law Quiz to ChemQuiz.net! Borrowed from PhysQuiz.net, the quiz now features diagrams and a new question type to calculate the force between an atom's nucleus and its outermost electron. Check it out & let me know what you think! chemquiz.net/cou #chemed #iteachchem #chemsky
A screenshot from the Coulomb's Law Quiz at ChemQuiz.net (https://chemquiz.net/cou/) shows a diagram of a polonium nucleus and its outermost electron with the question, "The atomic radius of polonium (Z = 84) is 1.35 × 10^-10 m. What is the magnitude of the electric force on its outermost electron?" A screenshot from the Coulomb's Law Quiz at ChemQuiz.net (https://chemquiz.net/cou/) shows a diagram of an iodine nucleus and its outermost electron with the question, "The nucleus of iodine (Z = 53) exerts -9.22 × 10^-7 N of force on its outermost electron. What is the atomic radius of iodine?" A screenshot from the Coulomb's Law Quiz at ChemQuiz.net (https://chemquiz.net/cou/) shows a diagram of a polonium nucleus and its outermost electron with the question, "Two charged particles, q1 = 3 × 10^-6 C and q2 = -1 × 10^-7 C, are arranged in such a way that they each experience -830 N of force. What is the distance between them?" A screenshot from the Coulomb's Law Quiz at ChemQuiz.net (https://chemquiz.net/cou/) shows a diagram of a polonium nucleus and its outermost electron with the question, "Three charged particles are placed in a line. The first particle has a charge of -7.2 x 10^-5 C and is found to the left of the other two. The second particle has a charge of 8.60 × 10^-4 C and is 1.90 x 10^-5 m to the right of the first particle. The third particle has a charge of 3 × 10^-6 C and is 7.0 × 10^-5 m to the right of the first particle. What is the magnitude of the force on the third particle?"
