Why do atoms share electrons in covalent bonds? Why do atoms form bonds? Why can carbon form so many compounds? Why are ionic bonds stronger than covalent? Does carbon form ionic or covalent bonds? What makes a covalent bond? Explain how the structure of the carbon atom affects the type ...
Elements forming ionic compounds attain noble gas electronic configuration by either gaining or losing electrons from their valence shells. Explain giving reason why carbon cannot attain such a configuration in this manner to form its compounds. Name the type of bonds formed in ionic compounds and in...
The lattice structure for both carbon and silicon is same with each of them having 4 bonding electrons c is an insulator wheres Si is semiconductor why View Solution The number of electrons in an insulator is of the same order as the number of electrons in a conductor. What is then the...
Rather than the lone pair of electrons contained in specific bonds (as in the valence-bond theory), the MO (molecular-orbital theory) theorizes that electrons exist in orbitals that are spread over the entire molecule. The MO theory explains molecules such as ozone and benzene, which cannot be...
So carbon's outer shell (n=2) has 4 electrons. The 2s subshell is full, but the 2p subshell can have 6 electrons, so when C bonds it tends to pick up the 4 electrons it needs to fill the shell, giving it a total of 8 valence electrons (mind you, there will not always be 8 ...
Explain why a carbon atom cannot form five bonds using sp3d hybrid orbitals. Describe the effect that non-bonding electron pairs might have on the molecular geometry. Use water as the example. How well does valence bond theory agree with the experimentally me...
The process is similar to how neon lights work: When the molecules and atoms get "excited" by electrons, they must return to their original energy (ground state) and do so by releasing the energy as photons (light). The color of the neon light depends on the gas mixture inside the ...
The basic principle of radiation therapy is to deliver energy to cancer cells through ionizing radiation. Radiation directly or indirectly interacts with the body's cells (when radiation passes through, its energy knocks out orbital electrons in atoms and separates them into cations, free electrons,...
The reason is simple. Some 15 years ago I wrote to Sir John Houghton, then chairman of IPCC’s climate “science” panel, and asked him why, given that direct warming by doubled CO2in the air was little more than 1 K, it was imagined that final warming was 3 or 4 K. Sir John...
In chemistry, a covalent bond is a chemical bond in which the outer shell electrons of the constituent atoms are shared between them when the molecule is formed. One example of a common molecule that has covalently bonded atoms is water....
