What else can I help you with?
Why does the repulsion between lone pairs are stronger than the repulsion between bonding pairs or between one bonding pair and a lone pair?
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?
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.
Why are prefixes used in naming covalent compounds?
The same atoms can combine in more than one ratio.
What is the molecular geometry of o2f2 or diflouride oxide?
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.
What is the number of lone electron pairs in the NO2 ion?
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.
How many pairs of congruent sides are there in a parallelogram?
2 pairs, the sides opposite each other are congruent to each other
Will pairs of electrons attract or repel each other?
Pairs of electrons will repel each other due to their negative charges.
Does pairs of a triangle bisect each other?
They can but need not.
True or false the closest capital cities to each other are Canberra and Sydney?
Out of Australia's capital cities, Canberra and Sydney are closest to each other.
What pairs of animals help each other?
pigeons make each other build nest and keep eggs warm
What two pairs have equal sides that are parallel to each other?
Rectangle
What is a nucleotide that pairs with guanine?
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.
Is canberra and sydney the closest capital cities to each other?
Queanbeyan, on the eastern border of Canberra, is the closest city.The closest capital city is Sydney.
What do electrons exist as?
Electrons exist as pairs. Although, electrons hate each other, and only go as pairs as a last resort.
How many pairs of parallel lines do a squarehave?
A square has 2 pairs of parallel lines, and those are the sides opposite from each other.
What 2 Australian cities are closest to each other?
Melbourne and Adelaide
What are alternate exterior angles?
they are angles that are usually parallel and that crossed the line that are oppsite from each other
