Atomic Structure of Elements

Preferred Language

Overview

Atoms are the smallest particles of an element that take part in chemical reactions without division. Each atom is made up of tiny particles called fundamental particles of subatomic particles or elementary particles. They are protons, neutrons and electrons. These particles can neither be created nor destroyed. Thus, an atom consists of sub-atomic particles. The targeted people of this model are the teachers and students of Grade 8, 9, 10 or students who are interested to learn about the topic “Atomic structure of elements”. Utilizing this model can help students with visual disabilities have a better concept of the atomic structure. Students can feel the model and identify how many electrons, protons and neutrons are present in the model and its symbol.

1. Start exploring the model from the top-left corner. You will find the name of the element written in braille.
2. Just below the name of the element, in the middle of the cardboard you will find the thread kept in round shape and you can find round shaped objects in different places of thread called “Beads”.
3. "Threads" are kept to represent the shell or orbit of atomic structure and “Beads” are kept to represent the electrons in that atomic structure.
4. In the center part of atomic structure, you can find the braille writing to represent the number of protons and neutrons which is assumed to be found in the center of atomic structure.
5. Just below the atomic structure on the left side you can find the braille writing representing Symbol, number of electrons, number of protons, number of neutrons simultaneously.
