A great way to understand chemistry is to use models representing atoms and molecules to see how they fit together. You will use plastic construction or building bricks, like LEGO bricks, as atoms of different elements. These models are based on the work ofMIT Edgerton CenterandLEGO. If you...
The electrons of the outermost energy level determine the energetic stability of the atom and its tendency to form chemical bonds with other atoms to form molecules.Under standard conditions, atoms fill the inner shells first, often resulting in a variable number of electrons in the outermost ...
