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
There are three lone pairs present in chlorine atom
two bonds and eight lone pairs
There are no lone pairs and it's tetrahedral.
linear
There are two lone pairs in nitrogen triiodide (NI3). Each nitrogen atom in NI3 has one lone pair of electrons, making a total of two lone pairs in the molecule.
Carbon disulfide (CS2) has 2 lone pairs of electrons on the sulfur atom, giving a total of 2 lone pairs in the molecule.
There are 2 lone electron pairs in the NO2 ion. The nitrogen atom has one lone pair, and each oxygen atom has one lone pair, totaling to 2 lone pairs.
IF6+ cation has no lone pairs, the IF6- anion has one lone pair. SF6 has no lone pairs.
Lone-pair electrons, Bonded pairs of electrons
The Si has no lone pairs, but each F has 6 lone pairs. Thus 6 x 4 = 24 lone pairs, total.
The NO2- ion has one lone electron pair.
