You determine the number of valence electrons for Beryllium (Be) by looking at its group number on the periodic table.
Determining Valence Electrons for Beryllium
Valence electrons are the electrons in the outermost shell of an atom and determine its chemical properties. Here's how to find them for Beryllium (Be):
- Locate Beryllium (Be) on the Periodic Table: Beryllium is in Group 2 (also known as Group IIA or the alkaline earth metals).
- Group Number Equals Valence Electrons: Elements in Group 2 have two valence electrons.
Therefore, Beryllium (Be) has two valence electrons. These two electrons are available for bonding with other elements.
