The Periodic table is organized according to Atomic
Number,
So the answer is 2nd OPTION
Atomic number is nothing but the number of protons/electrons in an atom.
here it is to emphasized that in a neutral atom the number of both electrons and protons are equal.
The periodic table is arranged in accordance with atomic number because the properties of elements are periodic(that means they follow certain fashion) in accordance to the number of electrons in the outer shell ( aka Valency shell)

The atomic mass of magnesium on the periodic table is based on three isotopes, ^24_12Mg, ^25_12Mg, and^26_12Mg. If a fourth isotope is discovered, it would change the abundances of all the others, and it would change the molar mass listed on the periodic table. Calculate the molar mass of magnesium, based on the masses and abundances given below.[^23_12Mg mass = 22.9862, abundance 22.50%] [^24_12Mg mass = 23.9850, abundance 62.49%] [^25_12Mg mass = 24.9858, abundance 10.20%]^26_12Mg mass = 25.9826, abundance 4.810%]
