Distribution of Electrons in the Electron Shells
Distribution of Electrons in the Electron Shells (Product Code: SCI-923/117) is a laminated wall chart used to teach how electrons are arranged in shells around the nucleus of an atom, in secondary-school and college chemistry and physics classes. At 70 cm x 100 cm it gives students a shared reference while they write electronic configurations and connect them to the periodic table. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Electron Shells Chart Used For?
In the shell model, electrons occupy energy levels labelled K, L, M and N, working outwards from the nucleus. At school level the first shell holds up to two electrons and the next shells fill in turn, giving configurations such as 2, 8, 1 for sodium or 2, 8, 7 for chlorine. The electrons in the outermost shell, the valence electrons, decide how an element bonds and which group of the periodic table it belongs to.
Teachers use the chart when introducing atomic structure, when explaining why elements in the same group behave alike, and as a lead-in to ionic and covalent bonding, where atoms gain, lose or share outer electrons. Students can build the same arrangements with atom models and compare them with the configurations discussed in class. It sits naturally beside the periodic table in any school chemistry lab.
OEM Manufacturer
ScienceLab, the trading name of Jain Scientific Equipments Private Limited, is the OEM that manufactures the Distribution of Electrons in the Electron Shells chart at its own licensed factory at Saha, Ambala, Haryana. Buying direct gives schools, colleges, dealers and importers one point of contact for quotations, repeat copies and questions about the artwork, instead of a chain of resellers. The chart is shipped factory-direct within India and to international markets. See the ScienceLab profile.

Frequently Asked Questions
What size is the Distribution of Electrons in the Electron Shells chart?
The Distribution of Electrons in the Electron Shells chart is 70 cm x 100 cm, laminated and designed for wall mounting in classrooms and laboratories. It is a convenient size to hang beside a periodic table on the chemistry wall.
Which elements does the chart cover?
The product listing for the Distribution of Electrons in the Electron Shells chart does not state how many elements are shown or whether sub-shells are included. Ask us to confirm the content and language before ordering if your syllabus needs a particular level of detail.
How many electrons can each shell hold?
In the model taught with the Distribution of Electrons in the Electron Shells chart, the first (K) shell holds up to two electrons and the second (L) shell up to eight. At school level the third shell is usually filled to eight before the fourth begins.
Why are valence electrons important?
Valence electrons, the outer-shell electrons discussed with the Distribution of Electrons in the Electron Shells chart, determine how an atom bonds and reacts. Elements with the same number of valence electrons sit in the same group and show similar chemical behaviour.
Who manufactures the Distribution of Electrons in the Electron Shells chart?
The Distribution of Electrons in the Electron Shells chart is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Quotations are provided directly by the manufacturer.
Can the chart be ordered for several classrooms or for export?
Yes. The Distribution of Electrons in the Electron Shells chart can be quoted in multiple copies for several classrooms, for school tenders, and for dealers and importers in India and international markets. Send the quantity and destination through our contact page.
