a让我难过的人 ,我会让你好过吗? Let my sad person, I can let you feel better?[translate] ahow many electrons are there in an iron atom? 多少个电子有没有在铁原子?[translate]
There are core electrons and valence electrons. The core electrons are close to the nucleus and do not participate in bonding. On the contrary, valence electrons are present in the outermost shell and take part in bonding. Answer and Explanation: ...
One way to measure and compare a magnet's "strength" is to see how many staples it can pick up. What is the difference between an iron and an aluminum core for the magnet? For example, roll up some aluminum foil tightly and use it as the core for your magnet in place of the nail...
While this is happening, the moving electrons also create a magnetic field. If you take the batteries out of your remote, it will likely retain a small magnetic charge. You couldn't pick up a car with your remote, but maybe you can pick up some small iron filings or even a paper clip...
Resistance is central to traditional soldering irons and to the Cold Heat iron. Electricity moves more easily through substances with lots of free electrons, like copper, than it does through substances with fewer free electrons, like carbon. In other words, substances like carbon have greater resi...
How many excess electrons are on the sock? If spin is not included, how many different wave functions correspond to the first excited level n = 2 for hydrogen? 1. 1 state 2. 5 states 3. 3 states 4. 2 states 5. 4 states How does faster-moving water between two ...
atoms have their electrons ripped off. These electrons are then able to traverse the gap, attracted by the positive electrode and in doing so, collide with other gas molecules and release more electrons. Eventually an avalanche of electrons occurs (all of this happening in a split second) and...
rely on the free flow of electrons through the electrolyte's crystal matrix. Displacing the electrolyte to deposit it in crystals elsewhere disrupts that electrical flow, and so does coronal discharge: the strange behavior of electronsaround corners and sharp edges, such as those of dendrite ...
Iron, for example, has four unpaired electrons with the same spin. Because they have no opposing fields to cancel their effects, these electrons have an orbital magnetic moment. The magnetic moment is a vector— it has a magnitude and a direction. It's related to both the magnetic field ...
“If we figure out how to harness this effectively and efficiently, this is it. This is the end. This is the solution,” an expert tells us.
