For the list of elements provided, the atomic symbol and the number of neutrons in the nucleus of each atom is:

Barium’s symbol is Ba and the number of protons is 56

Carbon’s symbol is C and the number of protons is 6

Fluorine symbol is F and the number of protons is 9

Europium symbol is Eu and the number of protons is 88

Bismuth symbol is Bi and the number of protons is 125

Hydrogen symbol is H and the number of protons is 0

Magnesium symbol is Mg and the number of protons is 12

Mercury symbol is Hg and the number of protons is 120

(The number of neutrons is calculated by subtracting the atomic number from the atomic mass, as atomic number is the number of protons and atomic mass is the sum of the neutrons and protons in the nucleus)
