Explain how the number of electrons in an energy level affects bond formation.
Klio2033 [76]

Hi,

The answer is very simple and of basic nature, let us get into the basics.

We have studied since very long that atoms form chemical bonds with other atoms because they want to get stable. They can get stable through octet or duplet rule that means that atoms needs to have two (in the shell nearest to nucleus) and eight electrons in the outer most shell.

So, if an atom already has enough number of electrons that it is obeying octet or duplet rule, it means that the atom is stable. It will tend not to form a chemical bond with other atom by sharing, losing or gaining electrons. Now, the electrons in outer most shell are called valence electrons and they are distributed in sub-energy levels, s and p respectively. S orbital can accommodate only two electrons, while P can accommodate 6 electrons, d can accommodate 10 electrons while f orbital can accommodate 14 electrons. So, we can say that the bond formation is the most important property of an atom and it is strongly effected by number of electrons in an energy level.

In addition, number of electrons in outer most shell also effect many other properties of an atom like shielding or screening effect, metallic or non-metallic nature that also effects the chemical bonding of atoms. Since, metallic nature of an atom is due to its ability to lose outermost shell's electrons. Therefore, the whole phenomenon of chemical bonding is linked with number of electrons in outer most shell.


Hope it helps!

Why might it be advantageous for a storage polysaccharide to have a branched-chain structure instead of a linear structure?
Vlada [557]
<span>The branched chain is more advantageous due to the increased availability of carbon ends to be hydrolyzed. The "branched" or many ended (more than two) polysaccharide molecule can liberate more free glucose for utilization than the linear polysaccharide chain with only two defined ends. All glucose molecules broken down for energy will continue to be hydrolyzed until it gets to the final monomer. If two polysaccharides with the same glucose molecules are side by side, the branched-chain structure will always be utilized faster than the linear structure.</span>
