Front

What is the significance of the electron configuration in determining an element's chemical properties?

Back

It determines how an element interacts with other elements and its reactivity.

Front

What is the Aufbau principle in electron configuration?

Back

Electrons fill the lowest energy orbitals first before moving to higher energy levels.

Front

What is Hund's rule in electron configuration?

Back

Every orbital in a subshell is singly occupied before any orbital is doubly occupied.
