10 lone pairs, 1 on N, 3 on each of the 3 Cl atoms (3*3=9+1=10)
The number 18.
Two pairs: 1 and 26 2 and 13
12 and 18 have three factor pairs.
Factor pairs are just the factors of a number listed in a different way. The factors of 20 are 1, 2, 4, 5, 10, 20 The factor pairs of 20 are (20,1)(10,2)(5,4)
36, for one.
1
two bonds and eight lone pairs
There will be a total of 10 lone pairs of electrons. In NI3, each I will have 3 lone pairs (total of 9) and the N will also have 1 lone pair, for a grand total of 10 lone pairs.
There are three lone pairs present in chlorine atom
There are no lone pairs and it's tetrahedral.
linear
IF6+ cation has no lone pairs, the IF6- anion has one lone pair. SF6 has no lone pairs.
14 ve- so 7 bonds/lone pairs. Cl will have three sets of lone pairs on it and F will have three sets of lone pairs on it. There is a single bond between Cl and F 1 bond, 6 lone pairs = total number of ve-
NO2 only has one lone electron
