Which of the following pairs of prefixes are closest to each other in size?
Repulsion between lone pairs is stronger because they are closer to the nucleus and repel more strongly than bonding pairs. Lone pairs have less electron-cloud shielding compared to bonding pairs, resulting in increased repulsion. This leads to lone pairs pushing each other apart more forcefully than bonding pairs do.
In a molecule of nitrogen (N2), the nitrogen atoms are bonded to each other by a triple covalent bond. This means that each nitrogen atom shares three pairs of electrons with the other nitrogen atom, creating a strong bond between them.
The molecular geometry of O2F2 (dioxygen difluoride) or difluoride oxide is bent/angular with an O-F-O bond angle of about 103 degrees. This is due to the presence of two lone pairs on the central oxygen atom, which repel the bonding pairs, leading to a bent molecular shape.
The same atoms can combine in more than one ratio.
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.
2 pairs, the sides opposite each other are congruent to each other
Pairs of electrons will repel each other due to their negative charges.
They can but need not.
Out of Australia's capital cities, Canberra and Sydney are closest to each other.

In DNA, nucleotide cytosine and guanine pairs with each other. Nucleotide adenine and thymine also pairs with each other. However in RNA, the thymine is not present, so in its place, uracil pairs with adenine.
Queanbeyan, on the eastern border of Canberra, is the closest city.The closest capital city is Sydney.
Melbourne and Adelaide
Electrons exist as pairs. Although, electrons hate each other, and only go as pairs as a last resort.
A square has 2 pairs of parallel lines, and those are the sides opposite from each other.
