Product Code : SCL-AS-12489
Quick Answer: The Formation of Sodium Ion Model shows a neutral sodium atom losing its single outer-shell electron to become a positively charged sodium ion, Na+.
Last updated: October 2026
Key Features
- Sodium has atomic number 11 and one valence electron
- Demonstrates the loss of that outer electron
- Shows why one fewer electron than protons gives a positive charge
- Introduces cations and their role in ionic compounds

About This Product
Teachers locate the outer electron on the neutral atom, demonstrate its removal and then identify the resulting ion. The before-and-after comparison makes cation formation clear and sets up lessons on electron transfer, ionic bonding, charge balance and writing chemical formulas. The Formation of Sodium Ion Model is available for supply within India and for export to Gambia, Madagascar, Suriname, Timor-Leste and Rwanda.
Frequently Asked Questions
Q1. Why does sodium form a positive ion?
A neutral sodium atom has one electron in its outer shell. When it loses that electron, the ion has one fewer electron than protons, so it carries a single positive charge.
