it´s actually Lithium and fluorine / Magnesium and Chlorine / Beryllium and Nitrogen
Higher value- mass number
Lower value- atomic number/ number of proton
Given :
An atom Iodine.
To Find :
How many electrons will an iodine atom donate or accept, based on its number of valence electrons :
A.donate seven electrons
B.accept one electron
C.donate one electron
D.accept seven electrons
Solution :
We know, valence electron in Iodine is 7 electrons.
So, it is easy for iodine to accept 1 electron rather than giving all 7 electrons to another element.
Therefore, Iodine will accept one electron ( Option B.).
Hence, this is the required solution.
I believe the answer is 4 carbons. Glycolysis involves break down of glucose to two molecules of pyruvic acid (3 carbons) under aerobic conditions. At the end of glycolysis the two pyruvate molecules undergoes pyruvate oxidation to capture the remaining energy in the form of ATP. A carboxyl group is removed from pyruvate and released in the form carbon dioxide, leaving a two carbon molecule which forms Acetyl-CoA (2 molecules). Acetyl-CoA then serves as a fuel for the citric acid cycle in the next stage of cellular respiration.
