Science Simulations
Energy band and band gap of atom According to Niels Bohr’s atomic model, electrons subordinate to an atomic nucleus do not have continuous energy. Electrons can only have sparsely defined energies. This is why lines in the atomic model represent … more
The discovery process of the atom Democritus (Ancient Greece) – Predict the presence of an atom Dalton (UK, 1800) – Applied atomic chemistry Krux (Britain, late 19th century) – Invented a cathode ray tube to explain various phenomena of electrons … more
Each click on the screen increases or decreases by 10 times. The structure of the atom The matter is composed of atoms such as hydrogen, carbon, nitrogen, and oxygen, and the size of the atom is about 10-10m. Atoms consist … more
Radioactive decay The radioactive material can collapse its own nucleus structure. At the same time, the nucleus emits some small particles or energy to the outside. The emitted particles and radioactive energy can cause damage to the human body. In … more
Discovery of nuclei At the beginning of the 20th century, little was known about atoms’ structure, except that atoms contain electrons. At the time, the atom was thought to be as a model of pudding containing raisins. According to this … more
The energy level of the atom Atoms are made up of an atomic nucleus and electrons that revolve around the nucleus. In Bohr’s atomic model, electrons can change their position by receiving energy (mainly light energy). But what’s unique is … more
* This simulation take the spectral data from NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY. When heat is applied to the atoms, some electrons can have high energy levels and fall to the lower levels. Some electrons emit as much energy … more
Orbital An atom has an atomic nucleus with a (+) charge at the center and electrons with a negative charge around it. Electrons are arranged according to certain rules (wave functions), which are called ‘orbitals.’ In an atom, electrons form … more
This simulation assumed that a candle emits all its energy in only one specific wavelength. The power of the candle is assumed to be 50W. The emitted wave diagram is for understanding only and does not represent the actual wavelength … more
Why we can’t see atoms under an optical microscope? The process by which we see objects is based on light. Therefore, the resolution of object recognition depends on the light. Just as a tool must be precise to open a … more
