Freely combine protons, neutrons, and electrons to create your own atom. Notes This simulation only provides tools for building atomic models and does not determine whether the completed atomic model is stable. For every number of … more
All atomic models showed only the electrons in the outermost shell. All chemical bonds are depicted as planar, but in reality, they can have three-dimensional structures. ‘In case of unstable, display in red’ may contain an … more
Neutralization reaction The reaction of an acid and a base to form water is called a neutralization reaction. When an acid and a base react, hydrogen ions from the acid (H+) and hydroxide ions from the … more
Free interactive science simulation(Virtual lab) written by JavaScript Simulates various natural phenomena Includes about Physics, Chemistry, Earth, Astronomy, Biology, Measurment, Mathmatics… No need to plugin add-ons Available on mobile devices and tablets also Free of charge … more
You can create ionic compounds by dragging and dropping atoms. Ion fragments that are no longer needed can be returned to their original location.
Why are the outermost electrons of atoms important? The outermost electrons of an atom are essential indicators of the properties of matter. Period 2 and 3 elements, such as carbon, oxygen, and nitrogen can exist in … more
You can create molecular structures by dragging the atoms. Atoms that no more needed can be returned to the periodic table.
Law of Definite Proportions In a reaction where hydrogen gas is burned to produce water, two hydrogen atoms combine with one oxygen atom. Hydrogen gas and oxygen gas always react in a ratio of 2:1 to … more
Arrange the element cards As Mendeleev did. You can move three or more consecutive cards as a group by dragging the middle. You can view it in full-screen mode by clicking the full-screen button. (There is … more
Ion Atoms are made up of an atomic nucleus and electrons. Electrons far from the atomic nucleus may easily fall off, or electrons from outside may enter. If a neutral atom loses an electron, the amount … more
2●\(\rightleftharpoons\)● Chemical equilibrium In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations that have no further tendency to change with time. In an equilibrium state at … more
* The gas molecules in the above simulation are all of the same type, and the color of the molecules is for identification purposes only. Kinetic Molecular Theory of Gases ‘Kinetic Theory of Gases’ is a … more
