An electron configuration is a method of indicating the arrangement of electrons about a nucleus. A typical electron configuration consists of numbers, letters, and superscripts with the following format: A number indicates the energy level (The number is called the principal quantum number.).
We will also look at how electrons are positioned and concept of orbital diagrams and how to determine valence shell configurations and what this means about the nature of the atom. Students will learn how to display valence shells with Lewis Dot diagrams.
use the electron-shell model to assign a simple electron-shell configuration to an atom or ion, interpret shell diagrams in order to identify potential atoms and ions, explain the relative stability of the shells in order to correctly fill electron shells with electrons in the correct order.
30 sie 2018 · This is a collection of the electron shell diagrams of all 118 elements. Each element’s atom is shown with the number of protons in the nucleus with shells of electrons filled by energy levels. The lowest energy level is closest to the nucleus.
Diagram Labeling – Visual aids where students label parts of an atom (e.g., electrons, nucleus, protons, neutrons) or differentiate between diagrams of individual atoms, molecules of elements, and compounds.
What is an element? What is a compound? What is an atom? What are subatomic particles? What is a proton? What is a neutron? -pure substance where all atoms are the same -cannot be broken down -can be a molecule -made up of two or more kinds of atoms [molecule] -atoms can be separated if enough energy is supplied -the smallest unit of matter
