Lewis Structures or Electron Dot Structures
2019/12/8· Lewis structures, also known as electron dot structures, are named after Gilbert N. Lewis, who described them in a 1916 article titled, "The Atom and the Molecule." Lewis structures depict the bonds between atoms of a molecule, as well as any unbonded electron

structures and physical properties of period 3 elements
2020/8/18· Silicon is a non-metal, and has a giant covalent structure exactly the same as carbon in diamond - hence the high melting point. You have to break strong covalent bonds in order to melt it. There are no obviously free electrons in the structure, and although it conducts electricity, it doesn''t do so in the same way as metals.
