1How do you write abbv. electron configurations?
[noble gas] and then rest of the configuration for element
2anomalus electron configurations
electron does not follow expected electron configuration and moves an energy level down, which makes the element more stable
3What elements tend to display anomalus electron configurations?
transition metals and elements near the bottom of the periodic table
4Hund's rule
^ is first, then v
5degenerate
orbitals at the same energy level
6aufbau/ building-up principle
elements in ground state "build up" in energy levels
7core electrons
occupy full shells and generally ignored due to stability
8valence electrons
electrons on the outer shell
9What do valence electrons dictate?
properties and reactivity of atoms and molecues
10d electrons are valence only for what elemental group?
transition metals
