Does N2H2 have any lone pairs?
Yes, N2H2 has lone pairs. Each nitrogen atom in N2H2 has one lone pair of electrons.
How many lone pairs in NO3?
There are no lone pairs in the nitrate ion (NO3-). The nitrogen atom forms three sigma bonds with oxygen atoms, leaving no non-bonding pairs of electrons.
How many lone pairs does Ge have?
Germanium (Ge) has 2 lone pairs of electrons.
How many molecules total do nf3 has around the central atom?
In NF3, the Nitrogen atom has 5 valence electrons and each Fluorine atom shares 1 more electron with Nitrogen. That makes 8 electrons (4 pairs of electrons) around Nitrogen. Betweent the four electron pairs, 3 pairs are bonded with Fluorine and the other one is a lone pair. Therefore around the central atom Nitrogen, there are three Fluorine atoms and a lone electron pair.
When two nitrogen atoms bond-they share three pairs of valence electrons. Why does this happen?
It happens so that each nitrogen atom can have 8 electrons (an octet), which is a stable form. It results in a nitrogen triple bonded to another nitrogen, and then each nitrogen has a lone pair of electrons. :N triple bond N:
