So the Hydrogens, they're OK, they all have 2 valence electrons. Nitrogen needs eight valence electrons for a full outer shell, or an octet, and Nitrogen has 8. So we're good. That is the structure for NH4+, the ammonium ion.

For the NO2- Lewis structure, calculate the total number of valence electrons for the NO2- molecule. After determining how many valence electrons there are in NO2-, place them around the central atom to complete the octets. There are a total of 18 valence electrons for the Lewis structure for NO2-.

Skeletal structure of N2 is given below. Each nitrogen atoms contribute 5 electrons and hence total number of valence electrons is 10. Each bond contributes two electrons. 2 electrons are reduced from the total number of valence electrons and the remaining 8 distributed on atoms so that it obeys octet rule.

Nitrogen has a total of 5 valence electrons, so doubling that, we would have a total of 10 valence electrons with two nitrogen atoms. The octet requires an atom to have 8 total electrons in order to have a full valence shell, therefore it needs to have a triple bond.

Answer and Explanation: The formula for ammonium iodide is NH4 I. Ammonium iodide is an ionic compound, which means that both ammonium and iodine have a charge.

Because NH4+ is a positive ion (called a cation) that means it lost one electron. When we write the Lewis structure for NH4+ we need to subtract one valence electron from out total. For the NH4+ Lewis structure we have a total of 8 valence electrons to work with.

For the peroxide ion, Oxygen has six valence electrons.

So number of valence electrons in chloride ion is 8.

Drawing the Lewis Structure for NO3- (Nitrate Ion) There are 24 valence electrons available for the Lewis structure for NO3-.

NH3 or commonly known as Ammonia is held together with covalent bonds, not ionic. This means that they're sharing electron pairs. The molecule is polarized with a slight positive charge on the H3 side and conversely a slight negative charge on the Nitrogen side.

Ammonia is a Lewis base, accepting proton to form ammonium ion as it has tendency to donate an electron pair. Hence it has a high proton affinity and C is correct answer.

For N2O4, we have a total of 34 valence electrons. N is the least electronegative.

Nitrogen is neither a cation nor an anion because it is an atom and atoms are electrically neutral. Nitrogen has five valence electrons and it needs...

The cyanide ion formula is CN–. That gives us ten valence electrons in total to work with.

So the valence shell will have 6+2=8 electrons in the case of oxide ion. Hence valence electrons of oxide ion is 8.

Ammonia (NH3), shown in the middle, has a lone pair of electrons, and since nitrogen is more electronegative than hydrogen, the nitrogen atom has a partial negative charge (red color). In this diagram, NH3 acts as a Lewis base,when it donates its lone pair of electrons to BF3.
