Electron Configuration Flashcards: All 118 Elements
Practice neutral-atom ground-state electron configurations for every named element, with NIST-based shorthand and clearly labeled predictions.
O ovom špilu
These 131 English flashcards practice neutral-atom ground-state electron configurations for all 118 currently named elements, from hydrogen through oganesson. Every element-to-configuration card includes the name, symbol, and atomic number. Thirteen extra reverse cards ask for the element behind a selected high-value irregular configuration.
What’s included
- 118 element-to-configuration cards in noble-gas shorthand.
- 13 configuration-to-element cards for Cr, Cu, Nb, Mo, Ru, Rh, Pd, Ag, Ce, Gd, Pt, Au, and Cm.
- A sequence by increasing atomic number, with each reverse card placed at least six unrelated cards after its matching forward card.
- The requested answer first on every back, with source qualifiers appended for lawrencium and the predicted elements 109–118.
- NIST ASD ground-shell assignments through hassium. Meitnerium through oganesson are labeled as PubChem/LANL predictions; lawrencium follows NIST’s current
7p¹assignment.
What’s excluded
The deck does not include full expanded configurations, ions, excited states, orbital-box diagrams, quantum numbers, derivation drills, oxidation states, or other element properties. It also avoids automatic reverse cards and separate name, symbol, and atomic-number permutations for every element.
Sources and reuse
The primary factual sources are the NIST Atomic Spectra Database, its ground-shell guidance, and the NIST periodic table. PubChem’s element pages expose property-level sources and provide the stated LANL prediction convention for elements 109–118. For roentgenium, this deck follows the exact PubChem element entry and LANL page, which both predict [Rn] 5f¹⁴ 6d⁹ 7s²; PubChem’s downloadable table instead lists [Rn] 5f¹⁴ 6d¹⁰ 7s¹. This documented source disagreement is not treated as a second accepted answer. IUPAC confirms the current names and symbols.
The questions, answers, selection, order, and cover were produced independently. No competitor cards, prose, tables, logos, or trade dress were copied. The CC0 label covers only the original wording, organization, metadata, and generated media that Open Study Contributor can license; it does not claim ownership of scientific facts or source material.
