Take online Tutorial of Electron Configuration Chemists write electron configurations (EC) to define and communicate the arrangement of electrons around the nucleus of atoms. This notation helps in predicting how atoms will join together to form chemical bonds and their behavior. Well, we have observed there are some kids who face difficulties to calculate it. In this post we are specially describing some of the effective ways that assist a kid to understand it and calculate it carefully.
What are electron configurations?
The cells in our bodies are masters of quantum physics. They have figured out the complex dance of atoms and electrons, and they use this knowledge to make an endlessly complex series of signaling pathways and genetic circuits. We, however, are not nearly as good at quantum mechanics, and so we must use careful notation if we wish to keep track of all the complex situations that the electrons in our bodies obtain themselves in. Electron configurations are a clear way of writing down the locations of all of the electrons in an atom. As we know, the positively-charged protons in the nucleus of an atom tend to attract negatively-charged electrons. While these electrons all stick within the atom due to the attraction to the protons, they also mutually repel each other, making them spread out around the nucleus in regular patterns. This appears in beautiful geometric structures called orbital’s that show the distinct regions around the nucleus that each electron traces out. The orbital’s show identifiable “addresses” for each electron around an atom. Imagine the electrons as being tenants in one of several blocks of studio apartments located near a nice park. The electrons all need to live near the nucleus, but they can’t all live in the same place. Instead, some electrons get to live in the homes nearest to the nucleus, but as the number of electrons that want to live near a given nucleus enhance, the further out some of them have to move since homes closer to the nucleus fill up. This explains a trend is seen in the periodic table.
Elements with a small atomic number tend to have most of their electrons living in orbital’s close the nucleus. As we move further down the periodic table, orbitals and energy levels further out from the nucleus start to fill up with electrons. Apart all, now you can learn this complex method with electron configuration videos online.
