Answer:
Rise in charge reduced the size due to rise in attraction between electron and nucleus.
Explanation:
Ion of magnesium is smaller than the atom of magnesium. As the nuclear charge increases, the attraction of electron to the nucleus increases in charged ions form of any element. Due to this increase in charge of magnesium ion, the size of ion reduces
No. of electrons in Mg = 12
No. of proton in Mg = 12
Where as
No. of electrons in Mg2+ = 12
No. of proton in Mg2+ = 10
Answer:1.
Explanation: This reaction is catalyzes by pyruvate dehydrogenase. Pyruvate being the end product of glycolysis has many fates after glycolysis,one of which is to enter the TCA(Tricarboxylic acid cycle) cycle. It is first converted to actetate by the action of pyruvate dehydrogenase. This enzyme converts pyruvate to acetate releasing CO2 and NADH because this oxidative decarboxylation of pyruvate is coupled with reduction of NAD+ which can feed into the electron transport chain.
Answer:
Hydrogen-1
Explanation:
Not sure what kind of explanation is needed for your question, because it doesnt specify.
The easiest should be:
Average mass of an element is calculated as the sum of the multiplication of each isotope by its percentage
And the mass of the hydrogen is 1, therefore the more abundant is hydrogen-1
