The electron-dot structure of sodium atom is 'Na-dot' or 'Na.'
One dot is one valence electron.
The valence electrons are either lost to another atom or the sodium atom gains valence electrons, it really depends on if what the sodium atom is bonding with has a lot or a little of valence electrons. The structure doesn't change though, just the number of valence electrons change. The nucleus is never changed when an ion is formed.
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.
the structure is as follows: Na + -:O:H ( I couldn't insert it in this box, but Oxygen (O) has 2 electrons above it and 2 electrons below it to fufil the octet.)
No. A cesium atom is larger both in terms of atomic mass and atomic radius.
A sodium ion differs from a sodium atom in that the sodium ion has a missing electron electron. It has a positive charge, as opposed to the atom, which is neutral.
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.

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.
There is none because there are no bonds in an atom.
The Lewis structure of an atom gives a clear illustration of the valence electrons.

The Lewis dot structure for cyanide has a C atom triple bonded to an N atom. each atom then has a pair of dots on the unattached sides.
The Lewis structure of carbononitridic chloride, or NCCl is as follows: A N atom is triple bonded to a C atom. The C atom is single bonded to a Cl atom. The N has one lone pair and the Cl has 3.
