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.
