GEOGEBRA APPLET


This Geogebra applet is designed to demonstrate the revolution of particles in circular orbits. In this applet, we have taken an example of Magnesium atom having 12 electrons revolving in three orbits at different speeds. In the first orbit, there are 2 electrons. In the second there are 8 electrons whereas in the third shell there are 2 electrons. The outer most shell is called the valence shell. The electrons present in the outer most shell take part in the formation of a bond. Mostly Magnesium forms an electrovalent or Ionic bond.

Speeds of electrons in the three shells
The speed of electrons depends upon their distance from the nucleus. The electrons in the first shell experience greatest force so to overcome this force they are moving at very high speeds. As they move away from the nucleus their speed decreases.

Usefulness
Our project can be helpful in explaining the structure of an atom with the electrons revolving in the shells at different speeds. Since impractical to show the structure of an atom in a science lab this applet may work as a good replacement.
This applet can provide a good introduction for a science teacher while initiating her lesson. We have so many elements on earth’s crust and this project can encourage other students to form similar models for other elements and try more challenging animations.

MAGNESIUM ATOM

Atom has come from the Greek word atomos. Atom is considered as the most smallest particle so using geogebra we have made an atom of magnesium in this project we have used variety of ways of mathematics like calculating the speed, counting the electrons, protons and nucleus. In this project we have also shown electrons revolving around the nucleus which are in different colour and different sizes.

We created the atom by first making a circle and then orbits inside it and made points which are revolving using animation and made the nucleus with points which are coloured.
Challenges we faced:
Although this was an interesting project, we still faced quite a few challenges. First of all it was difficult to show the animation that is revolution of electrons.
