Understanding Valence Electrons
* Valence Electrons: These are the electrons in the outermost energy level of an atom. They are the ones involved in chemical bonding.
* Sodium (Na): Sodium has an electron configuration of 2, 8, 1. This means it has 1 valence electron in its outermost shell.
Elements with the Same Number of Valence Electrons
Elements in the same group (vertical column) on the periodic table have the same number of valence electrons. Sodium is in Group 1 (also called Alkali Metals).
Therefore, there are many other elements that have the same number of outer electrons (1) as sodium. These elements include:
* Lithium (Li)
* Potassium (K)
* Rubidium (Rb)
* Cesium (Cs)
* Francium (Fr)
