H:Si:H (left and right side) H:Si:H (top and bottom) Silicon forms covalent bonds with 4 hydrogens. This completes the octet of silicon which has 4 valence electrons. Hydrogen is also stable because it needs 2 valence electrons to stabilize its "octet" because it only has a 1s orbital.

Silicon has 4 valence electrons, and hydrogen each has 1 valence electron. Silicon is in the center, with each of the four hydrogens around it. Silicon bonds once with each hydrogen. H | H-Si-H | H

I uploaded a jpg of the acetate ion Lewis structure to imageshack. Just click the "related link" below and you should see it. Many people draw Lewis Structures with minor variations, but this should give you the basic idea.
Calcium hydride, or CaH2, forms an orthorhombic lattice structure. For a Lewis structure of a single CaH2 molecule, simply place the Ca atom in the center single bonded to two H atoms.
carbon, germanium, tin, lead

lewis structure of Cl2O7
Lewis structure was created in 1916.
What is Lewis Structure for the bicarbonate ion
Yes, XeF4, or xenon tetrafluoride, has a Lewis structure.
No, not exactly. It is an ionic compound so it would not have a Lewis dot structure. However, the carbonate anion, CO3^2- does have a Lewis dot structure.
Potassium oxide (K2O) is an ionic compound, not a molecule, and does not have a Lewis structure.
