Answer:
For a hydrogen atom, H which has only one valence electron, the Lewis electron dot formula is with a single dot on the H atom.
For oxygen atom which has six valence electrons, the Lewis electron dot formula is shown with six dots around the O atom
For nitrogen atom with five valence electrons, the Lewis electron dot formula is shown with five dots around the N atom
For the hydrogen gas molecule, the Lewis electron dot formula is shown with two dots between the two H atoms which represents the bonding electrons.
For the oxygen gas molecule, the Lewis electron dot formula is shown with four dots between the two O atoms which represents the bonding electrons, and four other dots on each atom which represents the non-bonding electrons
For the nitrogen gas molecule, the Lewis electron dot formula is shown with six dots between the two N atoms which represents the bonding electrons, and two other dots on each atom which represents the non-bonding electrons
Explanation:
Lewis electron dot structures are structural formulas for molecules and polyatomic ions that represent all valence (outermost shell electrons involved in bonding with other atoms of the same or different elements) electrons in an atom of an element. It shows the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule. These electrons are represented with dots around the atom, thus the name Lewis electron dot formula.
The Lewis electron dot formula for the given atoms and molecules are explained below:
For a hydrogen atom, H which has only one valence electron, the Lewis electron dot formula is with a single dot on the H atom.
For oxygen atom which has six valence electrons, the Lewis electron dot formula is shown with six dots around the O atom
