Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. Some atoms can be stable with an octet even though their valence shell is the 3n shell, which can hold up to 18 electrons.
Answer:
<h2>ATP, RNA, NAD and DNA.</h2>
Explanation:
A nitrogenous base; it is an organic molecule containing a nitrogen, carbon and other atoms that has the chemical properties of a base that is why they are called as bases. The nitrogenous bases are; i) adenine, ii) guanine, iii) thymine, iv) uracil and v)cytosine.
Adenine is a nitrogenous base which is found in ATP, RNA. NAD, FAD and DNA. adenine pairs with thymine in DNA synthesis.
First step is to balance the amount of atoms on each side
So for example if my equation that I have to balance is : Br2 -> Br-
First thing I would have to do would be :
Br2 -> 2Br-
Then I would have to balance the charges on both sides. So because there is a -2 charge on the right side I will have to add a -2 charge onto the right side as well. I would do this by :
Br2 + 2e- -> 2Br-
And now you can see the amount of atoms and the charges are balanced... So your overall reaction is now balanced too.
