the atomic number is on the Periodic Table of elements... its the very top number in the box above the symbol so it's 63, don't let the 151 fool you or trip up your mental footing... all the atomic numbers are there...
The mass number of 151Eu. Its atomic number is 63, which means it has 53 protons in its atomic nuclei. No. of neutrons = mass no. - atomic no.
151 - 63 = 88
So 151Eu has a mass number of 151, atomic number of 63, and 88 neutrons.
The symbol for europium is 'Eu'. It is a lanthanide element , a no. 63 in the Periodic Table.
Eu, which is unusually clear for an elemental symbol. But then, Europium is one of the recently discovered elements, and had never acquired a handful of names in other languages.
"Eu"
Eu. For all element symbols the first letter is capitalized and the second is lowercased

It is not, The mass number is (A). The symbol for atomic mass is (ma)
Nitrogen has a gram atomic mass of 14.0067, an atomic number of 7, and the chemical symbol N.
the symbol scientists use to represent the atomic mass number is the letter U.
The element symbol represents one mole of element , atomic number represents number of protons, atomic mass represents sum of protons and neutrons.
Titanium, atomic number 22 with an Atomic Mass of 47.867 amu, is represented with the symbol Ti.
