Science Simulations
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 error. Chemical Bonding Except … 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 a very stable state … more
You can create molecular structures by dragging the atoms. Atoms that no more needed can be returned to the periodic table.
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 of (+) charge becomes … more
Formation and energy of the ionic bonds Metal atoms have strong properties to lose electrons and become cations. On the contrary, non-metallic atoms have strong properties to obtain electrons and become anions. As these two particles approach each other, electrons … more
What is Covalent Bond? The covalent bond is a bond formed by atoms. Each atom creates an electron pair and shares it. Because each other’s electrons are shared in pairs, the number of electrons involved in sharing is always even. … more
Looking through the VR device, you can observe the 3-dimensional molecular bonding structure of ice.
Press the ‘C’ button to add carbon, press the ‘H’ button to add a hydrogen atom, and press the ‘O’ button to add an oxygen atom. The added atoms are randomly placed and may not give the correct shape. You … more
Surface tension Surface tension is a type of force that acts to minimize the surface of liquids. Liquid molecules are pulling together with other molecules around them. This force is called a ‘cohesive force.’ On the other hand, molecules on … more
Formation and energy of the ionic bonds Metal atoms have strong properties to lose electrons and become cations. On the contrary, non-metallic atoms have strong properties to obtain electrons and become anions. As these two particles approach each other, electrons … more
The ductility and malleability of metal When a force is applied to a metal crystal, the metal atom layer is pushed, and the atomic arrangement changes. But at this time, the free electrons move and maintain the bond between the … more
