Isotopes have the same number of protons so they both have 17 and a different amount of neutrons which is why the mass number is different
Its been almost a year since i've been in chemistry, so sorry if its not right. Cs, Ba, Rb, Sr, Xe. I think that the levels of ionozation increase from the bottom left corner of the periodic table and increase as you go up and to the right
The number of repetition of the Beta oxidation requires to fully convert 18 carbon activated fatty acid to Acetyl COA molecule is NINE.
Beta oxidation of fatty acid involves oxidative removal of successive two carbon units in the form of acetlyl COA, starting from the carboxyl end of the fatty acyl chain. Thus, a fatty acid which has 18 carbons will have to undergo nine repetition of beta oxidation before it is reduced to an acetyl COA.
