Bahasa Melayu: Model Bohr dari atom hidrogen menggambarkan elektron-elektron bermuatan negatif mengorbit pada kulit atom dalam lintasan tertentu mengelilingi inti atom yang bermuatan positif. Ketika elektron meloncat dari satu orbit ke orbit lainnya selalu disertai dengan pemancaran atau penyerapan sejumlah energi elektromagnetik hf.

As a consequence, the model does not provide a clear insight about the space occupied by the model. In this aspect, ball-and-stick models are distinct from space-filling (calotte) models , where the sphere radii are proportional to the Van der Waals atomic radii in the same scale as the atom distances, and therefore show the occupied space but ...
Diffraction spikes are lines radiating from bright light sources, causing what is known as the starburst effect [1] or sunstars [2] in photographs and in vision. They are artifacts caused by light diffracting around the support vanes of the secondary mirror in reflecting telescopes , or edges of non-circular camera apertures , and around ...
