，原句为“子曰：“有教无类”。不管什么人都可以受到教育，不因为贫富、贵贱、智愚、善恶等原因把一些人排除在教育对象之外。此教育理念为孔子所倡导，在教育对象问题上，孔子明确提出了“有教无类”的思想。“有教无类”的意思是无分贵族与平民，不分国界与华夷，只要有心向学，都可以入学受教 ...
Identify the atom whose electron configuration is [Ar]4s^23d^6. Write the one or two letter symbol for the element. How many unpaired electrons are there in the ground state of this atom? Write the electron configuration for oxygen and state the number o...

The cathode, the positive post of the fuel cell, has channels etched into it that distribute the oxygen to the surface of the catalyst. It also conducts the electrons back from the external circuit to the catalyst, where they can recombine with the hydrogen ions and oxygen to form water. ...
oxygen-hydrogen (O - H) The chemical bonds between the atoms are shared pairs of electrons. Chemical bonds are much like springs: They can bend and stretch. These properties are important in detecting ethanol in a sample by infrared (IR) spectroscopy. Read More Types of Devices: Intoxilyze...
This is due to using a single, aligned silicon crystal, resulting in an easier flow for the electrons generated through the photovoltaic effect. Polycrystalline cells have shards of silicon aligned in many directions, making electricity flow slightly more difficult. However, solar modules made with ...
There are many different ways to produce photons, but all of them use the same mechanism inside an atom to do it. This mechanism involves the energizing of electrons orbiting each atom's nucleus. How Nuclear Radiation Works describes protons, neutrons and electrons in some detail. For example,...
Firstly, photosystem II oxidizes H2O to oxygen using the energy from sunlight captured by chlorophyll. This process, also known as photolysis of water or splitting of the H20 molecule, produces excited electrons. Simultaneously, the oxidizing agent NADP+ is reduced to NADPH, and oxygen is released...
Before we can consider that question, it helps to ask something much more fundamental: how exactly do electric cars work? What's so good about them anyway—and what are the drawbacks? Can you really go to work powered by a few buzzing electrons? Let's take a closer look!
