electrons are able to come relatively close to each other because, the electrons are transferred from one element to another and they bonds due to opposite charges. they involve metal bonding to non-metals stronger the bond types.
There are a few different reasons why electrical forces dominate between atoms that are close together. These atoms want to become stable so they share energy for example.
They dominate because the attraction forces between these two atoms are stronger than the repulsive force.
Oxygen is much more electronegative and has greater affinity for the electrons.
Oxygen is more electronegative; meaning that it has a 'liking' for electrons since it would like to fill up it's valency. Therefore it seeks to pull the electron between itself and carbon more strongly.
similarity: both have bonds involving four shared electrons. differences: c=o is polar; c=c is not polar.
Two electrons are transferred between calcium and oxygen to form calcium oxide.
yes, an oxygen atom have the same number of valence electrons as a selenium atom.
Plants incorporate inorganic carbon (carbon dioxide) into organic compounds by the Calvin Cycle (light-independent reactions). However, the Calvin Cycle does not release oxygen. The oxygen produced in photosynthesis is actually released in the first stages of light-dependent reactions. Plant photosynthesis depends on an acyclical electron flow, and therefore to replenish electrons lost by the photosystems, water is split into protons, electrons, and oxygen to supply electrons to the photosystems. The protons are used to generate the proton gradient. The oxygen, which has no further use, is released from the plant. Therefore, the oxygen produced by photosynthesis is not from carbon dioxide, by from water.
Usually, electrons are more attracted to atoms of elements that are located farther to the right and closer to the top of the periodic table; they are closer to the oxygen atoms than they are to the carbon atom. ~Ayanna91~
4 electrons.
Valence electrons are shared between oxygen atoms, Four valence electrons are shared.
Carbon would share electrons with the oxygen to form carbon monoxide or carbon dioxide.
The bond between carbon and oxygen is moderately strong. This results from the fact that oxygen has a stronger attraction for electrons (in other words a higher electronegativity) than carbon does, so if carbon shares its electrons with oxygen, there is much less energy expended upon pulling the electrons away from a carbon atom, than the energy that is gained by giving them to an oxygen atom.
The structure of CO2 is like: O=C=O In this structure, the bonded pair of electrons is shown as the lines between oxygen and carbon atoms. So, two electrons from each oxygen atom and four electrons from the carbon atom takes part in the bonding.
this is a strange bond that forms (for example) with CO, carbon monoxide when the octet rule cannot be satsified by ordinary means. covalent bonds require all atoms get a full orbital of electrons. they share the valence electrons to do so. Carbon has 4 valence electrons, oxygen has six. to combine them together, with carbon dioxide, it's easy to see how the carbon shares two valence electrons with each oxygen, and the oxygen shares two valence electrons back to the central carbon, both oxygen and carbon share 8 electrons with carbon being double bonded to both oxygens. with carbon monoxide, carbon shares 2 electrons in a double bond to oxygen because oxygen only needs to get 2 electrons. this leaves carbon "short" electrons. carbon has 4 valence electrons, borrows 2 back in the double bond from oxygen, but this leaves only six for carbon which is unstable. so... oxygen shares a pair of its unbonded electrons with the carbon as well, the coordinate covalent bond. usually electrons are shared by both atoms to form a bond. the C=O double bond does not make carbon stable, so the carbon octet is made possible by oxygen sharing 2 of its electrons, but both of these electrons are "oxygen" only electrons.
The answer is c. Valence electrons are shared between oxygen atoms & D. Four valence eletrons are shared
If you take O2 the bond between them where electrons are shared equally; there is no electronegativity difference between them whereas if you take CO (carbon monoxide) the bonds are made between electronegative difference element in which case Ois more electronegative than C.
Oxygen is more electronegative; meaning that it has a 'liking' for electrons since it would like to fill up it's valency. Therefore it seeks to pull the electron between itself and carbon more strongly.
non-polar covalent
Two electrons 'at one side' of carbon are shared with 2 electrons of one oxygen atom, forming a double bond (each bond is formed one pair of electrons), at the other side the same is happening to the other two 'carbon' electrons with the second O atom. Usually each pair of electrons is drawn by a short line (horizontally, sometimes also vertically) to draw the molecular bonding structure: For carbon dioxide O=C=O or in dots (one for each electron) O::C::O
