Thus, the number of protons in an atom identifies it as an atom of a particular element. The number of protons in an atom is referred to as the atomic number. 因此,原子中的质子数决定了原子的种类。原子中的质子数等于其原子序数(元素序数)。 The information provided by the periodic table for...
There's a huge amount of theory around electron orbitals, but to understand light there is just one key fact to understand: An electron has a natural orbit that it occupies, but if you energize an atom, you can move its electrons to higher orbitals. A photon is produced whenever an ...
The activity at the boundary between some of these plates is the primary catalyst for magma production. Where the different plates meet, they typically interact in one of four ways: If the two plates are moving away from each other, an ocean ridge or continental ridge forms, depending on ...
A bionic arm is an artificial limb with electronically controlled moving parts. They are typically made out of materials like carbon fiber and silicone, and often include myoelectric sensors and motors.

Next, Niels Bohr applied Planck's ideas to refine the model of an atom. Earlier scientists had demonstrated that atoms consist of positively charged nuclei surrounded by electrons orbiting like planets, but they couldn't explain why electrons didn't simply spiral into the nucleus. In 1913, Bohr...
Antimicrobial resistance (AMR) is an urgent public health threat. Advancements in artificial intelligence (AI) and increases in computational power have resulted in the adoption of AI for biological tasks. This review explores the application of AI in ba
In addition to this, the team also discovered the role of light intensity in the molecular assembly process. Prof. Yagai explains, “We identified that the intensity of visible light potentially affected the timing of the assembly. Strong visible light promoted rapid assembly while minimizing the ...
