→Reactivity along Period 2
The [[reactivity]] decreases as you go across the [[Period (Chemistry)|period]]:
*The outer [[electron]]s are all roughly the same distance away from the [[Atomic Nucleus|nucleus]]
*The [[charge]] on the [[Atomic Nucleus|atomic nucleus]] increases as you move go across the [[period]]but the [[electron]] shielding caused by the two inner [[electron]]s remains the same.This causes the [[electron]]s to experience a greater [[force]] of [[attraction]] as you move along the [[period]], making it harder for the [[atom]]s to lose [[electron]]s and become [[ion]]s.
