New cards

What are the steps to figuring out Electron Config using the periodic table?

Steps

  1. Start at H

  2. Move through the rows, top to bottom, left to right until you get to your given element

  3. Each box adds one electron

  4. Electrons go in orbital listed for that row

New cards

What are the two exceptions to Electron Config?

  1. Chromium

  2. Copper

5
New cards

Why is Chromium an exception to electron configs?

Chromium takes on this configuration because a half-filled orbital has extra stability.

6
New cards

Why is Copper an exception to electron configs?

Copper takes on this configuration because a totally filled orbital has extra stability.
