Electron Configurations Video Workbook: Explanation, Examples, & Practice @wbreslyn

Uploaded May 2024 | Updated September 2026, 2 weeks ago

This video on writing electron configurations for the elements accompanies the guide at Breslyn.org . You'll learn faster and remember longer is you watch the video and do the electron configuration practice problems as you watch.

One of the quickest ways to write electron configurations is to remember the trend for the orbital blocks on the Periodic Table. This way you'll be able to figure out the last term in an configuration for an element just by knowing its position on the Periodic Table.

Remember that when we write electron configurations we are generating a description of how electrons are arranged around the nucleus of an atom. Based on this information we can determine considerable information about how the atom might react to form chemical bonds, it's charge when forming ionic compounds, and other valuable information.

Electron Configurations Video Workbook: Explanation, Examples, & Practice

$Convert 6.5 L to mL (6.5 Liters to Milliliters) To convert 6.5 liters (L) to milliliters (mL), you can use the following steps. Note that the L will cancel out as you perform the conversion, leaving only mL: Conversion Factor: 1 liter (L) = 1000 milliliters (mL) Start with the quantity you want to convert (6.5 L) and set up a ratio where the original unit (L) is in the denominator and the target unit (mL) is in the numerator, using the conversion factor: Conversion factor: 1000 mL / 1 L Write the quantity you want to convert (6.5 L) as a fraction over 1: 6.5 L / 1 Multiply this fraction by the conversion factor: (6.5 L / 1) * (1000 mL / 1 L) Notice that the units of liters (L) in the numerator and denominator cancel out, leaving only the units of milliliters (mL): (6.5 * 1000) / (1 * 1) mL = 6500 / 1 mL = 6500 mL So, 6.5 L is equivalent to 6500 milliliters. The units of liters cancel out during the conversion process, leaving only milliliters as the final unit.$

$Convert 4.0 L to mL (4 Liters to Milliliters) To convert 4 liters (L) to milliliters (mL), you can use the following steps. Note that the L will cancel out as you perform the conversion, leaving only mL: Conversion Factor: 1 liter (L) = 1000 milliliters (mL) Start with the quantity you want to convert (4 L) and set up a ratio where the original unit (L) is in the denominator and the target unit (mL) is in the numerator, using the conversion factor: Conversion factor: 1000 mL / 1 L Write the quantity you want to convert (4 L) as a fraction over 1: 4 L / 1 Multiply this fraction by the conversion factor: (4 L / 1) * (1000 mL / 1 L) Notice that the units of liters (L) in the numerator and denominator cancel out, leaving only the units of milliliters (mL): (4 * 1000) / (1 * 1) mL = 4000 / 1 mL = 4000 mL So, 4 L is equivalent to 4000 milliliters. The units of liters cancel out during the conversion process, leaving only milliliters as the final unit.$
