What is Hund's Rule?

Back

Hund's Rule states that electrons will fill degenerate (equal energy) orbitals singly before pairing up in any orbital.

FLASHCARD QUESTION

Front

How do you determine the group of elements with similar chemical properties?

Back

Elements in the same group (vertical column) of the periodic table have similar chemical properties due to having the same number of valence electrons.

FLASHCARD QUESTION

Front

What are the alkali metals?

Back

Alkali metals are the elements in Group 1 of the periodic table, which include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). They are known for being highly reactive.

FLASHCARD QUESTION

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties, allowing for the prediction of element behavior.
