The Three E's - Exciting Energetic Electrons

Ready for a lab with a lot of razzle-dazzle? Young chemists observe flame tests of common salts through an always-popular activity. The updated resource focuses on observation skills, collaboration, and green chemistry practices.

Scientists used flame tests to identify elements long before the invention of emission spectroscopy. Young chemists observe a flame test of five metal cations in the fourth lesson of an 11-part series. Individuals then work...

It's electronic! Pupils uncover elements and their electron configurations as they explore mass, groupings, correct charges, and sliding theory. Young scientists learn creative ways to remember various elements and correctly...

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...

How can you tell the difference between chemical compounds, when so many of them are white and powdery? The fifth installment in a series of ten videos exposes learners to flame tests and formation of insoluble compounds as methods...

High schoolers perform flame tests on 12 elements. In this flame tests lesson plan, students experiment with elements to observe their visible light spectra emitted as electrons jump from one energy level to another. High schoolers...

Flame tests determine if there is a specific metal in a chemical compound. Young forensic scientists review their understanding of flame tests and hydroxide precipitates by solving puzzles. The timed review encourages mastery.

This is an online exercise in which chemistry learners answer a series of multiple choice questions about bonding. Topics addressed include ionic and covalent bonds, electronegativity, ions, valence electrons, resonance structure, and...

A review of the electron configurations and orbital notations with a focus on K, Ca, and Sc. [12:33]

Let the true colors shine through. Pupils conduct a flame test to identify an unknown element. Class members calculate and prepare specific molarity solutions of three chemicals. Using their observations of the colors emitted, they...
