Quick Answer:The Formation of Sodium Ion Model is a chemistry model that shows a sodium atom losing the one electron in its outermost shell to become the positively charged sodium ion, Na+. It is used to teach cation formation and valency.

How It Is Used
The teacher identifies the sodium atom, points to its single outer electron and removes that indicator to form Na+. Learners then discuss why losing the electron leaves a stable arrangement, and how the sodium ion goes on to take part in ionic bonding.
Frequently Asked Questions
What change does the Formation of Sodium Ion Model show?
