What takes up more space a lone pair or a single bond?
A lone pair
Why the repulsion caused by lone pair is greater than bonding pair?
lone pair has more electrons than bond pair
Why will atoms join together?
Atoms join together to become more stable. For example, a lone Na+ (sodium ion) will bond with a lone Cl- (Chlorine Ion) to form the stable compound NaCl (table salt).
A sponge and a bar of soap occupy the same amount of space but the soap is much more dense than the sponge.?
Yes that is right.
What are postulates of vsepr theory?
1: Both the lone pairs asa well as the bond pairs participate in determining the geometery of the molecules 2: The electron pairs are arranged around the central polyvalent atom so as to remain at a miximum distance apart to avoid repulsions 3: The electron pairs of lone pairs occupy more space then the bond pairs from ncert:- 1)The shape of a molecule depends upon the number of valence shell electron pairs (bonded or nonbonded) around the central atom. 2)Pairs of electrons in the valence shell repel one another since their electron clouds are negatively charged. 3)These pairs of electrons tend to occupy such positions in space that minimise repulsion and thus maximise distance between them. 3)The valence shell is taken as a sphere with the electron pairs localising on the spherical surface at maximum distance from one another. 4)A multiple bond is treated as if it is a single electron pair and the two or three electron pairs of a multiple bond are treated as a single super pair. 5) Where two or more resonance structures can represent a molecule, the VSEPR model is applicable

A lone pair
Why does a lone pair of electrons occupy more space on an atom?
It doesn't exactly occupy more space, but it has a different shape to a bond pair. In a bond pair we have two positive nuclei, with most of the density of the bonding electron pair between the atoms. The outer nucleus attracts the bond pair outwards from the central atom. In a lone pair there is only the central atom to attract the electrons, so they are pulled in more than the bond pair, producing a fatter, squatter shape. This means that more of the electron density is near the central atom than with a bond pair, which makes it more effective at repelling the other electron pairs. Thus there is a difference in the amount of repulsion between different sorts of pair, meaning that he angles between them are different too, in the order, from greatest to least, lone pair-lone pair, lone pair-bond pair, bond pair-bond pair.
Why does the presence of lone pairs contribute to the polarity of a water molecule?
How do lone pairs around the central atom affect the polarity of the molecule?
Why is it that the bond angle for CBr4 is 109.5?
That is the tetrahedral angle. Each bromine is equivalent and carbon has no lone pairs. Therefore they have to be distributed evenly in space (in 3d space, so it is more than 90 degrees!)
When a fluid increases does its particles occupy less space?
Liquids, solids and gasses EXPAND when heated- the particles occupy more space.
Why the lone pair-lone pair repulsion is more than bond pair-bond pair?
In bonded pairs of electrons the repulsion of the negative charges is somewhat reduce by the positive charge of the bonded atom's nucleus. Lone pairs do not have this.
What occurs when two or more waves occupy the same space at the same time-?
When two or more waves occupy the same space at the same time, an interference pattern is created.
Why the repulsion caused by lone pair is greater than bonding pair?
lone pair has more electrons than bond pair
Why does air occupy more space when heated?
air expands whenheated
Do solid occupy space?
Yes, a solid, liquid, gas as well as the other states of matter all occupies space. 2. But the space occupied by gases and liquids is not necessarily of fixed dimensions.
Why does air have more nitrogen than oxygen?
because it is light in weight there for occupy more space
Does Green occupy more space in the spectrum visible to the human eye?
Yes, it does!
