Yes, it is true.
No. For an isotope of an element, the number of neutrons, not protons, in the nucleus of an atom of the isotope is equal to the isotopic mass number minus the atomic number. The atomic number itself is the number of protons in the nucleus.
The average number of neutrons that a specific element has is equivilent to the element's atomic mass minus the that elements atomic number. For example Helium has 2 neutrons because its atomic mass (4) minus the atomic number (2) is 2.
By subtracting the mass number and the atomic number, the number of neutrons can be calculated.

Atomic weight of an element is the number of protons plus neutrons in the nucleus, atomic number is the number of protons only.
Mass number minus atomic number = number of neutrons
Roughly, the number of neutrons. Note that the atomic mass is only approximately equal to the number of protons plus the number of neutrons - there is a relatively small discrepancy, due to the binding energy.
The number of protons and electrons is equal to the atomic number in a neutral atom.The number of protons is the mass number minus number of protons.
The number of neutrons is equal to the atomic mass of an isotope minus the atomic number (or the protons number) of the element. The atomic number of mendelevium is 101 and Md has isotopes with atomic masses between 245 and 260.
