Lewis dot formula
Lewis dot structures show how an atom's electrons work together in a certain molecule. They also show what a certain molecule will look like.
There is no such ion like AlH4-!? This molecule can exist only bonded with atom, for example Lithium, where Lithium is bonded for Aluminium and fourth Hydrogen atom is connected for Lithium.
bond length between 2 atoms
The Lewis structure for SiH3- is very simple. The Si atom is treated like a C atom. It will be placed in the center, with three H atoms single bonded to it, and a -1 formal charge indicated at the Si atom.
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.
There is none because there are no bonds in an atom.
This is an ionic compound. Sodium is positively charged and is paired with the negatively charged BH4 molecule, which, in Lewis dot structure form, comprises a boron atom connected to four H atoms.
The Lewis structure of an atom gives a clear illustration of the valence electrons.

Two covalent bonds attach both Oxygen atoms to the Carbon atom. You should have figured that out using the Lewis structure.
The Lewis structure for OF2 is:.. .. ..:F-O-F:'' '' ''We know that this is the best structure because the formal charge on each atom is 0, and the overall charge of the molecule is 0. Even without formal charge calculations we can predict this structure because we know that Halogens, such as Fluorine, never form double bonds.
The correct Lewis Structure for the oxygen atom will be an 'O' with two dots above and below, with one dot on the left and on the right sides.
