Electron Configuration and Orbital Filling

The video tutorial explains how to find the electron configuration for hydrogen by using the periodic table to determine the number of electrons. Hydrogen, having one electron, is placed in the 1s orbital. The tutorial also briefly mentions how to proceed with electron configurations for other elements by filling the 2s, 2p, and 3s orbitals sequentially.

What information do we use from the periodic table to determine the number of electrons in an element?

• The element's group number

• The element's atomic mass

• The element's period number

• The element's atomic number

Why is hydrogen's electron configuration considered simple?

• It has only one electron

• It has a complex orbital structure

• It shares electrons with other elements

• It has a full outer shell

Which orbital is filled first when determining the electron configuration for hydrogen?

• 3s orbital

• 2s orbital

• 2p orbital

• 1s orbital

How many electrons can the 's' orbital hold?

• Four

• One

• Two

• Three

After filling the 1s orbital, which orbital is filled next for elements beyond hydrogen?

• 2s orbital

• 3s orbital

• 2p orbital

• 3p orbital

What is the next step in electron configuration after filling the 2s orbital?

• Fill the 2p orbital

• Fill the 3p orbital

• Fill the 1s orbital

• Fill the 3s orbital
