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.
Which occupies a greater about of space free electron pairs or bonding pairs?
bonding pairs, the electrons from each ion reach to the other nuclei because of the inter magnetic force attracting the two atoms. Because the ions must reach to another atoms orbital they require more space than a free electron in a single atom.
How many lone pairs of electrons exist on the central atom in oxygen O?
SIMPLY-The element Oxygen can either capture two electrons or share two electso just for the more techy side......ns.The Electron Structure of OxygenOxygen atoms have 8 protons and therefore 8 electrons in their neutral state. If we follow the subshell filling guide for elements, we end up with this: 1s2 2s2 2p4. This tells us that Oxygen has two shells of electrons. The first is holds only two electrons and is completely filled. The second contains six electrons, with space for another two electrons to make the full complement of 8 which is necessary for stability. As these outer shell electrons are arranged in pairs, we get the electron dot diagram for Oxygen as shown to the left. We can see from this that Oxygen will want to either capture two electrons or share two electrons to achieve stability.We can see a more detailed image of the electron structure of the Oxygen element below. Subshells are indicated by the black horizontal lines. The numbers in brackets show the maximum number of electrons that can be placed in that subshell is the number given in brackets.
What has the strongest repulsion bonding pairs or lone pairs?
Lone pairs typically have the greater repulsion because lone pairs want to be as far apart from one another as possible, even more so than bonding pairs. This is because the lone pairs consist of free-moving electrons.
What is negative ionisation?
Negative ionisation is usually the result, in ionic bonding, of adding one or more electrons to an atom, molecule or even an negative ion. The last of these goes more negative.
