0, Cbonds to 3 H and to C. Second C triple bonds to N .
H
H C-C---N:
H
i think it can either have 1 lone pair in a resonance form with a double bond or 0 when there is a triple bond between the 2 c's
One
Two lone pair
No lone pairs on the N in the nitrate anion (NO3^-)
Four pairs of electrons. Neon has a full octet.
IF6+ cation has no lone pairs, the IF6- anion has one lone pair. SF6 has no lone pairs.
The Si has no lone pairs, but each F has 6 lone pairs. Thus 6 x 4 = 24 lone pairs, total.
3 Lone pairs and one unpaired electron
Three bonds and no lone pairs.
One
No lone pairs
The lone pairs are on the bromine atom- 3 in all.
3 bond pairs and no lone pairs
two bonds and eight lone pairs
Two lone pair
No lone pairs on the N in the nitrate anion (NO3^-)
There are three lone pairs present in chlorine atom
Four pairs of electrons. Neon has a full octet.
