Triboelectricity
When you rub a balloon on a cat, it charged. Charged balloons can be attached to walls or cat. The charged balloon rolls down as it discharges after a certain period of time. Triboelectricity If you peel off a thin … more

Photoelectric Effect Experiment
Photoelectric Effect The photoelectric effect is the phenomenon that the electrons pop out when a light beam incident on a metal surface. It can be thought that the energy of light is transformed into the form of electrical energy. However, … more

Covalent Bond
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
Spectrum of Hydrogen Atom
Spectrum of hydrogen At the time of Rutherford’s experiments, chemists analyzed chemical components using spectroscopy, and physicists tried to find what kind of order in complex spectral lines. For example, a hydrogen arc tube containing hydrogen, a light element, shows … more
Electron Configuration of an Atom
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
